Public-key cryptography
 
44:57
Public-key cryptography, also known as asymmetric cryptography, is a class of cryptographic algorithms which require two separate keys, one of which is secret (or private) and one of which is public. Although different, the two parts of this key pair are mathematically linked. The public key is used to encrypt plaintext or to verify a digital signature; whereas the private key is used to decrypt ciphertext or to create a digital signature. The term "asymmetric" stems from the use of different keys to perform these opposite functions, each the inverse of the other -- as contrasted with conventional ("symmetric") cryptography which relies on the same key to perform both. Public-key algorithms are based on mathematical problems which currently admit no efficient solution that are inherent in certain integer factorization, discrete logarithm, and elliptic curve relationships. It is computationally easy for a user to generate their own public and private key-pair and to use them for encryption and decryption. The strength lies in the fact that it is "impossible" (computationally infeasible) for a properly generated private key to be determined from its corresponding public key. Thus the public key may be published without compromising security, whereas the private key must not be revealed to anyone not authorized to read messages or perform digital signatures. Public key algorithms, unlike symmetric key algorithms, do not require a secure initial exchange of one (or more) secret keys between the parties. This video is targeted to blind users.

IoT Device Identification for O-MI/O-DF
 
03:01
Paper info: "MeDI: Measurement-based Device Identification Framework for Internet of Things" Narges Yousefnezhad, Manik Madhikermi, Kary Främling Department of Computer Science, Aalto University, Espoo, Finland Abstract—IoT systems may provide information from different sensors that may reveal potentially confidential data, such as a person’s presence or not. The primary question to address is how we can identify the sensors and other devices in a reliable way before receiving data from them and using or sharing it. In other words, we need to verify the identity of sensors and devices. A malicious device could claim that it is the legitimate sensor and trigger security problems. For instance, it might send false data about the environment, harmfully affecting the outputs and behavior of the system. For this purpose, using only primary identity values such as IP address, MAC address, and even the public-key cryptography key pair is not enough since IPs can be dynamic, MACs can be spoofed, and cryptography key pairs can be stolen. Therefore, the server requires supplementary security considerations such as contextual features to verify the device identity. This paper presents a measurement-based method to detect and alert false data reports during the reception process by means of sensor behavior. As a proof of concept, we develop a classification-based methodology for device identification, which can be implemented in a real IoT scenario. Description (more information): The reference implementation (Otaniemi3D) of open messaging standards (O-MI/O-DF) is developed by Aalto University and an example scenario (EV charging) is provided as a proof of concept. This research paper provides device-side identification using sensor measurements and classification methods.
NDSS 2018 - Mind Your Keys? A Security Evaluation of Java Keystores
 
17:21
SESSION 2B: Crypto: 01 Mind Your Keys? A Security Evaluation of Java Keystores SUMMARY Cryptography is complex and variegate and requires to combine different algorithms and mechanisms in nontrivial ways. This complexity is often source of vulnerabilities. Secure key management is one of the most critical aspects, since leaking a cryptographic key vanishes any advantage of using cryptography. In this paper we analyze Java keystores, the standard way to manage and securely store keys in Java applications. We consider seven keystore implementations from Oracle JDK and Bouncy Castle, a widespread cryptographic library. We describe, in detail, how the various keystores enforce confidentiality and integrity of the stored keys through password based cryptography and we show that many of the implementations do not adhere to state-of-the-art cryptographic standards. We investigate the resistance to offline attacks and we show that, for non-compliant keystores, brute-forcing can be up to three orders of magnitude faster with respect to the most compliant keystore. Additionally, when an attacker can tamper with the keystore file, some implementations are vulnerable to denial of service attacks or, in the worst case, arbitrary code execution. Finally we discuss the fixes implemented by Oracle and Bouncy Castle developers following our responsible disclosure.

What is HOST IDENTITY PROTOCOL? What does HOST IDENTITY PROTOCOL mean? HOST IDENTITY PROTOCOL meaning - HOST IDENTITY PROTOCOL definition - HOST IDENTITY PROTOCOL explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ The Host Identity Protocol (HIP) is a host identification technology for use on Internet Protocol (IP) networks, such as the Internet. The Internet has two main name spaces, IP addresses and the Domain Name System. HIP separates the end-point identifier and locator roles of IP addresses. It introduces a Host Identity (HI) name space, based on a public key security infrastructure. The Host Identity Protocol provides secure methods for IP multihoming and mobile computing. In networks that implement the Host Identity Protocol, all occurrences of IP addresses in applications are eliminated and replaced with cryptographic host identifiers. The cryptographic keys are typically, but not necessarily, self-generated. The effect of eliminating IP addresses in application and transport layers is a decoupling of the transport layer from the internetworking layer (Internet Layer) in TCP/IP. HIP was specified in the IETF HIP working group. An Internet Research Task Force (IRTF) HIP research group looks at the broader impacts of HIP. The working group is chartered to produce Requests for Comments on the "Experimental" track, but it is understood that their quality and security properties should match the standards track requirements. The main purpose for producing Experimental documents instead of standards track ones are the unknown effects that the mechanisms may have on applications and on the Internet in the large.

Cryptography: ------------- Cryptography or cryptology is the practice and study of techniques for secure communication in the presence of third parties called adversaries. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages; various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, electrical engineering, communication science, and physics. Applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymous with encryption, the conversion of information from a readable state to apparent nonsense. The originator of an encrypted message shares the decoding technique only with intended recipients to preclude access from adversaries. The cryptography literature often uses the names Alice ("A") for the sender, Bob ("B") for the intended recipient, and Eve ("eavesdropper") for the adversary.[5] Since the development of rotor cipher machines in World War I and the advent of computers in World War II, the methods used to carry out cryptology have become increasingly complex and its application more widespread. ----------------------Java Cryptography More Videos--------------------------- 1.

DEF CON 24 - Jake Kambic - Cunning with CNG: Soliciting Secrets from Schannel
 
41:17
Secure Channel (Schannel) is Microsoft's standard SSL/TLS Library underpinning services like RDP, Outlook, Internet Explorer, Windows Update, SQL Server, LDAPS, Skype and many third party applications. Schannel has been the subject of scrutiny in the past several years from an external perspective due to reported vulnerabilities, including a RCE. What about the internals? How does Schannel guard its secrets? This talk looks at how Schannel leverages Microsoft's CryptoAPI-NG (CNG) to cache the master keys, session keys, private and ephemeral keys, and session tickets used in TLS/SSL connections. It discusses the underlying data structures, and how to extract both the keys and other useful information that provides forensic context about connection. This information is then leveraged to decrypt session that use ephemeral cipher suites, which don't rely on the private key for decryption. Information in the cache lives for at least 10 hours by default on modern configurations, storing up to 20,000 entries for client and server each. This makes it forensically relevant in cases where other evidence of connection may have dissipated. Bio: Jake Kambic is a DFIR researcher and network penetration tester

Best Practices from Google Production Security: How You Can Apply Them with Istio (Cloud Next '19)
 
46:36
Google production network security lead, Julien Boeuf, and Istio product manager, Samrat Ray, talk about zero trust network security principles that Google uses to protect millions of service endpoints in its production environment and how organizations can apply them using Istio. This is especially relevant to enterprises adopting containers and microservices -- the dynamic and distributed nature of these new deployments and emergent threats within the network perimeter pose unique challenges to traditional network security approaches. Istio can help enterprises transform their security posture from just securing the edge to securing all inter-service communications deep within their applications.

What is BGP HIJACKING? What does BGP HIJACKING mean? BGP HIJACKING meaning & explanation

What is BGP HIJACKING? What does BGP HIJACKING mean? BGP HIJACKING meaning - BGP HIJACKING definition - BGP HIJACKING explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. BGP hijacking (sometimes referred to as prefix hijacking, route hijacking or IP hijacking) is the illegitimate takeover of groups of IP addresses by corrupting Internet routing tables maintained using the Border Gateway Protocol (BGP). The Internet is a global network in enabling any connected host, identified by its unique IP address, to talk to any other, anywhere in the world. This is achieved by passing data from one router to another, repeatedly moving each packet closer to its destination, until it is safely delivered. To do this, each router must be regularly supplied with up-to-date routing tables. At the global level, individual IP addresses are grouped together into prefixes. These prefixes will be originated, or owned, by an autonomous system (AS) and the routing tables between ASes are maintained using the Border Gateway Protocol (BGP). A group of networks that operate under a single external routing policy is known as an autonomous system. For example, Sprint, Verizon, and AT&T each are an AS. Each AS has its own unique AS identifier number. BGP is the standard routing protocol used to exchange information about IP routing between autonomous systems. Each AS uses BGP to advertise prefixes that it can deliver traffic to. For example, if the network prefix 192.0.2.0/24 is inside AS 64496, then that AS will advertise to its provider(s) and/or peer(s) that it can deliver any traffic destined for 192.0.2.0/24. Although security extensions are available for BGP, and third-party route DB resources exist for validating routes, by default the BGP protocol is designed to trust all route announcements sent by peers, and few ISPs rigorously enforce checks on BGP sessions. IP hijacking can occur deliberately or by accident in one of several ways: An AS announces that it originates a prefix that it does not actually originate. An AS announces a more specific prefix than what may be announced by the true originating AS. An AS announces that it can route traffic to the hijacked AS through a shorter route than is already available, regardless of whether or not the route actually exists. Common to these ways is their disruption of the normal routing of the network: packets end up being forwarded towards the wrong part of the network and then either enter an endless loop (and are discarded), or are found at the mercy of the offending AS. Typically ISPs filter BGP traffic, allowing BGP advertisements from their downstream networks to contain only valid IP space. However, a history of hijacking incidents shows this is not always the case. The Resource Public Key Infrastructure (RPKI) is designed to authenticate route origins via cryptographic certificate chains demonstrating address block range ownership, but is not widely deployed yet. Once deployed, IP hijacking through errant issues at the origin (via both accident or intent) should be detectable and filterable. IP hijacking is sometimes used by malicious users to obtain IP addresses for use in spamming or a distributed denial-of-service (DDoS) attack. Like the TCP reset attack, session hijacking involves intrusion into an ongoing BGP session, i.e., the attacker successfully masquerades as one of the peers in a BGP session, and requires the same information needed to accomplish the reset attack. The difference is that a session hijacking attack may be designed to achieve more than simply bringing down a session between BGP peers. For example, the objective may be to change routes used by the peer, in order to facilitate eavesdropping, black holing, or traffic analysis.

What is Raven Coin? How to mine RVN? Most profitable coin to mine!
 
00:57
Mine Raven Coin with Mining Program and your NVIDIA GPU. https://miningprogram.com Ravencoin Roadmap Phase 1 - Complete Ravencoin (RVN) is a Proof of Work coin built on the Bitcoin UTXO model. As with other Bitcoin derivatives, RVN coins are distributed to persons augmenting the Raven network by mining Raven. x1000 coin distribution (21 Billion Total) 10x faster blocks (1 per minute) In app CPU mining ~1.4 Day difficulty adjustment (2016 blocks) Addresses start with R... for regular addresses, or r... for multisig Network Port: 8767 RPC Port: 8766 Phase 2 - Assets (in progress) ASIC Resistance ASIC Resistance - A published commitment to continual attempts at ASIC resistance. If ASICs are created for x16r, then we will, at a specific block number, modify one of the algorithms to add Equihash, EthHash or similar efforts to increase the resistance to ASIC miners for Raven. Asset Support Ravencoin will be a hard fork that extends Raven to include the ability to issue and transfer assets. The expected release of asset capabilities will be approximately seven months after the release of RVN. Raven will be extended to allow issuing, reissuing, and transfer of assets. Assets can be reissuable or limited to a set supply at the point of issuance. The cost to create assets will be 500 RVN to create any qty of an asset. Each asset name must be unique. Asset names will be limited to A-Z and 0-9, '' and '.' and must be at least three characters long. The '.' and the '' cannot be the first, or the last character, or be consecutive. The RVN used to issue assets will be sent to a burn address, which will reduce the amount of RVN available. Asset transfers require the standard RVN transaction fees for transfer from one address to another. Metadata Metadata about the token can be stored in IPFS. Initially this cannot be changed. If there is a demand, the system can be updated to allow updating the metadata by the token issuer. Rewards Reward capabilities will be added to allow payment (in RVN) to all holders of an asset. Payments of RVN would be distributed to all asset holders pro rata. This is useful for paying dividends, dividing payments, or rewarding a group of token holders. Example: A small software company issues an asset GAMECO that represents a share of the project. GAMECO tokens can be traded with others. Once the software company profits, those profits can be distributed to all holders of GAMECO by sending the profits (via RVN) to all holders of GAMECO. Block Size Raven may increase the blocksize from 1 MB to X MB to allow for more on-chain transactions. Phase 3 - Rewards Rewards allow payment in RVN to asset holders. Phase 4 - Unique Assets Once created, assets can be made unique for a cost of 5 RVN. Only non-divisible assets can be made unique. This moves an asset to a UTXO and associates a unique identifier with the txid. From this point the asset can be moved from one address to another and can be traced back to its origin. Only the issuer of the original asset can make an asset unique. The costs to make unique assets will be sent to a burn address. Some examples of unique assets: Imagine that an art dealer issues the asset named ART. The dealer can then make unique ART assets by attaching a name or a serialized number to each piece of art. These unique tokens can be transferred to the new owner along with the artwork as a proof of authenticity. The tokens ART:MonaLisa and ART:VenusDeMilo are not fungible and represent distinct pieces of art. A software developer can issue the asset with the name of their software ABCGAME, and then assign each ABCGAME token a unique id or license key. The game tokens could be transferred as the license transfers. Each token ABCGAME:398222 and ABCGAME: are unique tokens. In game assets. A game ZYX_GAME could create unique limited edition in-game assets that are owned and used by the game player. Example: ZYX_GAME:Sword005 and ZYX_GAME:Purse RVN based unique assets can be tied to real world assets. Create an asset named GOLDVAULT. Each gold coin or gold bar in a vault can be serialized and audited. Associated unique assets GOLDVAULT:444322 and GOLDVAULT:555994 can be created to represent the specific assets in the physical gold vault. The public nature of the chain allows for full transparency. Phase 5 - Messaging Messaging to token holders by authorized senders will be layered on top of the Phase 3 unique assets. See KAAAWWW Protocol for additional information. Phase 6 - Voting Voting will be accomplished by creating and distributing parallel tokens to token holders. These tokens can be sent to RVN addresses to record a vote.

Triple DES
 
08:06
In cryptography, Triple DES (3DES) is the common name for the Triple Data Encryption Algorithm (TDEA or Triple DEA) symmetric-key block cipher, which applies the Data Encryption Standard (DES) cipher algorithm three times to each data block. The original DES cipher's key size of 56 bits was generally sufficient when that algorithm was designed, but the availability of increasing computational power made brute-force attacks feasible. Triple DES provides a relatively simple method of increasing the key size of DES to protect against such attacks, without the need to design a completely new block cipher algorithm.

Elliptic curve cryptography
 
18:25
Elliptic curve cryptography is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. One of the main benefits in comparison with non-ECC cryptography is the same level of security provided by keys of smaller size. Elliptic curves are applicable for encryption, digital signatures, pseudo-random generators and other tasks. They are also used in several integer factorization algorithms that have applications in cryptography, such as Lenstra elliptic curve factorization. This video is targeted to blind users.

Vint Cerf | Talks at Google
 
01:17:26
Googlers are lucky to have among them some great luminaries of computer science, including VP and Chief Internet Evangelist Vint Cerf. If you dont know Vint, you can start by checking out his nearly 380,000 mentions on Google, the pivotal roles hes played in developing the web, the significant honors he's received all over the world, and his nickname, father of the Internet. You can learn more by attending a rare tech talk by Vint, presented by the Greyglers*: Reimagining the Internet: If we'd known then what we know now, what would we have done differently? Back in the Internet's design phase, Bob Kahn and I spent six months developing concepts and architecture and a year creating the TCP specification, but we didn't know that the idea would work. We concentrated on solving the problems we envisioned, such as networks that couldn't handle each other's packet lengths. Security against direct attacks and authentication of sources weren't high on the agenda. Now that we have spam, DDOS, viruses, and worms, we look back and think about what we might have done differently had we realized that we were creating a global infrastructure for the 21st century!

Bitcoin Q&A: How to avoid re-creating systems of control
 
18:40
What are the implications of blockchain projects that re-create the same financial systems of control that we currently have? Should we use banks for custodial cryptocurrency services? Are there benefits to permissioned, centralised blockchains for supply chain management, digital rights management (DRM), healthcare data, or tokens for senior citizens’ credit? Why is decentralisation of control and minimising trusted third parties in finance is more important? What should we learn from the demonetisation & Gresham's Law in India? Can we achieve our dreams without capitulating on principles? These questions are from the MOOC 9.6 session, the June monthly Patreon session, and part of the Denver talk, which took place on March 23rd, June 24th, and August 6th 2018 respectively.

WITx Talks - PUF: The Magic Circuit (for Hardware Security)
 
43:51
Join Aaron Carpenter and Nate Derbinsky in this WITx Talk! Traditionally, security algorithms rely on random, but deterministic algorithms created in software. Unfortunately, random number generators are typically not truly random. This work explores the designs of Physical Unclonable Functions (PUFs), which provide hardware random numbers, leveraging the inherent manufacturing unpredictability for individual transistors. These circuits provide random numbers for cryptographic functions and digital signatures, skipping the software generation entirely. Meanwhile, in a growingly complicated and power-constrained microprocessor environment, large portions of the chip remain "dark" or without power.As much of the on-chip coach remains off at a given rime, we can repurpose portions as PUF circuits, creating a large array of random numbers for cryptographic functions.
