The Ten Commandments of Encryption Policy
 
03:41
Here's something I wrote a few weeks ago and I've been spreading around, and encouraging others to do so as well. The formatted version I put on my DeviantArt journal is linked to below, and I've provided the raw text as well; feel free to copy it and spread it around anywhere you think it'll do good--especially to politicians. The Ten Commandments of Encryption Policy by shanedk on DeviantArt http://shanedk.deviantart.com/journal/The-Ten-Commandments-of-Encryption-Policy-634133886 So many politicians, bureaucrats, and pundits are proposing weakening our crypto to allow searches by law enforcement without understanding the issue, so I thought it'd be good to have a quick reference to explain why this is a bad idea. Feel free to copy this and send to politicians, news reporters, or anyone else you think needs to know this. The Ten Commandments of Encryption Policy 1. In "Applied Cryptography" (2nd Ed., John Wiley & Sons, 1996), Bruce Schneier wrote: "There are two kinds of cryptography in this world: cryptography that will stop your kid sister from reading your files, and cryptography that will stop major governments from reading your files." Therefore, anything that allows our government to read our messages will automatically put our crypto into the "kid sister" category. 2. Anything that allows government to read your message will also allow hackers to read your message. Cryptography is just math, and math works the same for everybody. It doesn't distinguish between good people and bad, or who has a warrant and who doesn't. 3. When strong crypto is outlawed, only outlaws will have strong crypto. The encryption genie is already out of its mathematical bottle. Weakening our crypto so our governments can read it will only make us vulnerable to hacker groups and terror organizations like ISIS, who will have no hesitation about breaking the law to use strong crypto themselves. 4. "If you have nothing to hide, you have nothing to worry about" is a very dangerous mantra. Just ask anyone who's had their identity stolen. 5. When people talk about giving law enforcement authorities access to our data, remember that they're talking about the same law enforcement authorities who illegally tapped Martin Luther King Jr.’s phones. 6. Terror attacks, mass shootings, and mass hackings are all proof that we cannot rely on laws to protect us. We need to protect ourselves with math. Protecting our data is too important to be left to governments. 7. Always remember that lawmakers want solutions that are visible, that they can point to and say, "See? It works." But security solutions that ACTUALLY work are invisible. People go about their lives unaware of the attacks they were protected from. People don't notice the days their house DOESN'T get burgled. 8. Don't be caught up in considering how much security you "need." You won't know how much that is until after the worst happens and it's too late. We need to be able to give ourselves every last bit of security that we can. 9. Before you bring up the founders or the Constitution, remember that they themselves often communicated using ciphers. Thomas Jefferson even invented a wheel cipher for this purpose. 10. We need to consider the consequences of constant observation. Every bit of human progress began as an idea that most people opposed. The last thing we want to do is make people afraid to express those ideas.

PCI Requirement 3.5.2 Restrict Access to Cryptographic Keys
 
01:28
PCI Requirement 3.5.2 states, “Restrict access to cryptographic keys to the fewest number of custodians necessary.” There should be very few employees who have access to your organization’s cryptographic keys. Typically, only those deemed “key custodians” have this type of access. In order to comply with PCI Requirement 3.5.2, your organization needs to maintain strict access controls around who has access to cryptographic keys in order to prevent an unauthorized user from gaining access to the encryption/decryption keys. Wherever keys reside, there needs to be strict control. Whether that’s in a safe, somewhere electronic, or backed up, an assessor will want to examine where your keys reside. An assessor will also want to see the list of users who have access to keys, and ensure that the list includes the fewest number of key custodians as possible. If you store, process, or transmit cardholder data, interact with payment card data in any way, or have the ability to impact someone else’s cardholder information or the security of that information, you are subject to comply with the PCI DSS. This exclusive video series, PCI Demystified, was developed to assist your organization in understanding what the Payment Card Industry Data Security Standard (PCI DSS) is, who it applies to, what the specific requirements are, and what your organizations needs to know and do to become compliant. Learn more at https://kirkpatrickprice.com/video/pci-requirement-3-5-2-restrict-access-cryptographic-keys/ Video Transcription If we’re encrypting cardholder data – or any other data for that matter – and somebody gains access to your encryption/decryption keys, chances are it’s game over. They can look to decrypt that data or gain access to it. PCI DSS Requirement 3.5.2 states that your organization needs to maintain strict access controls around who has access to these keys. There’s going to be several places, from an assessment perspective, that we look to see where these keys are stored. You might have them physically in a safe somewhere, we might look to see how you’re storing them electronically, we might ask how you’re backing them up. In any event, wherever these keys reside, you need to maintain strict control over those particular keys.

USENIX Security '17 - Phoenix: Rebirth of a Cryptographic Password-Hardening Service
 
28:41
Russell W. F. Lai, Friedrich-Alexander-University Erlangen-Nürnberg, Chinese University of Hong Kong; Christoph Egger and Dominique Schröder, Friedrich-Alexander-University Erlangen-Nürnberg; Sherman S. M. Chow, Chinese University of Hong Kong Password remains the most widespread means of authentication, especially on the Internet. As such, it is the Achilles heel of many modern systems. Facebook pioneered using external cryptographic services to harden password-based authentication in a large scale. Everspaugh et al. (USENIX Security ’15) provided the first comprehensive treatment of such a service and proposed the PYTHIA PRF-Service as a cryptographically secure solution. Recently, Schneider et al. (ACM CCS ’16) proposed a more efficient solution which is secure in a weaker security model. In this work, we show that the scheme of Schneider et al. is vulnerable to offline attacks just after a single validation query. Therefore, it defeats the purpose of using an external crypto service in the first place and it should not be used in practice. Our attacks do not contradict their security claims, but instead show that their definitions are simply too weak. We thus suggest stronger security definitions that cover these kinds of real-world attacks, and an even more efficient construction, PHOENIX, to achieve them. Our comprehensive evaluation confirms the practicability of PHOENIX: It can handle up to 50% more requests than the scheme of Schneider et al. and up to three times more than PYTHIA.

2012 IEEE Secure Overlay Cloud Storage with Access Control and Assured Deletion
 
06:23
TO Get this Project Contact Me @9493059954 or mail me @[email protected]­­m We can now outsource data backups off-site to third-party cloud storage services so as to reduce data management costs. However, we must provide security guarantees for the outsourced data, which is now maintained by third parties. We design and implement FADE, a secure overlay cloud storage system that achieves fine-grained, policy-based access control and file assured deletion. It associates outsourced files with file access policies, and assuredly deletes files to make them unrecoverable to any one upon revocations of file access policies. To achieve such security goals, FADE is built upon a set of cryptographic key operations that are self-maintained by a quorum of key managers that are independent of third-party clouds. In particular, FADE acts as an overlay system that works seamlessly atop today's cloud storage services. We implement a proof-of-concept prototype of FADE atop Amazon S3, one of today's cloud storage services. We conduct extensive empirical studies, and demonstrate that FADE provides security protection for outsourced data, while introducing only minimal performance and monetary cost overhead. Our work provides insights of how to incorporate value-added security features into today's cloud storage services..

Privacy and Access Control for Outsourced Personal Records
 
18:19
Privacy and Access Control for Outsourced Personal Records Manuel Reinert Presented at the 2015 IEEE Symposium on Security & Privacy May 18--20, 2015 San Jose, CA http://www.ieee-security.org/TC/SP2015/ ABSTRACT Cloud storage has rapidly become a cornerstone of many IT infrastructures, constituting a seamless solution for the backup, synchronization, and sharing of large amounts of data. Putting user data in the direct control of cloud service providers, however, raises security and privacy concerns related to the integrity of outsourced data, the accidental or intentional leakage of sensitive information, the profiling of user activities and so on. Furthermore, even if the cloud provider is trusted, users having access to outsourced files might be malicious and misbehave. These concerns are particularly serious in sensitive applications like personal health records and credit score systems. To tackle this problem, we present GORAM, a cryptographic system that protects the secrecy and integrity of outsourced data with respect to both an untrusted server and malicious clients, guarantees the anonymity and unlink ability of accesses to such data, and allows the data owner to share outsourced data with other clients, selectively granting them read and write permissions. GORAM is the first system to achieve such a wide range of security and privacy properties for outsourced storage. In the process of designing an efficient construction, we developed two new, generally applicable cryptographic schemes, namely, batched zero-knowledge proofs of shuffle and an accountability technique based on chameleon signatures, which we consider of independent interest. We implemented GORAM in Amazon Elastic Compute Cloud (EC2) and ran a performance evaluation demonstrating the scalability and efficiency of our construction.

The Controlled Unclassified Information Program
 
11:49
The CUI Program is an important reform of the current patchwork of confusing agency-specific policies that have resulted in inconsistent marking and safeguarding of documents, led to unclear or unnecessarily restrictive dissemination policies, and created impediments to authorized information sharing. As the Program is implemented, we can appreciate that the sharing and protecting of information under the CUI Program is an art practiced by civil servants in every department and agency, and their non-Federal partners, working on behalf of the American people. In support of this program for the entire Executive branch, this video will explain these concepts and tools, so fundamental to the entire lifecycle of CUI: · The definition of CUI, and the distinctions between types of information provided in the CUI Registry · Marking requirements overall, for email, and for packages and standard mail; · Controlled Environments, both physical and electronic; · The principles of access and sharing as they apply to Lawful Government Purpose and Limited Dissemination Control markings; · The Reproduction of CUI; · FAXing CUI; · Reporting incidents; · The Destruction of CUI; and · The acceptable indicators for the Decontrol of CUI F​or additional information please visit the CUI Registry at https://www.archives.gov/cui or follow the CUI Blog at https://isoo.blogs.archives.gov/ ​

Creating Realistic Cyber Security Policies for Industrial Control Systems, Lee Cysouw
 
43:56
Crafting a cyber security strategy that is simple enough to actually be implemented, yet nuanced enough to be effective is no easy task. By reconciling IT security solutions’ prioritization of confidentiality against ICS’s prioritization of availability, this session will present the principles that a successful cyber security policy can be built around. This requires an understanding of the threats ICS will face in terms of probability, not possibility, which includes an explanation of how current ICS strategies fail. Policy foundations will then be presented that allow proven IT security strategies to be successfully applied to ICS legacy networks. Description

Ronny Boesing OpenLedger CEO about Crypviser. Blockchain and Bitcoin Conference in Prague
 
01:01
Blockchain and BItcoin Conference in Prague, May 19, 2017 Crypviser’s solutions not only prevent information leakages to third parties, but also eliminates man-in-the-middle attacks, local data storage vulnerabilities and allows detection of unauthorized interception attempts through integrated intrusion detection algorithms. Crypviser Secure Protocol (CSMP) provides real end-to-end encryption and a blockchain-based, disruptive public keys distribution model. Every message sent over the platform is encrypted at the users’ side before it is transmitted over the network. At the same time, a unique public key authentication algorithms enables the parties to verify each other’s public keys manually in peer-to-peer mode (for FREE subscription), or automatically through Blockchain transactions. It also provides local level security for storing data within a device using a symmetric 256-bit encryption key, based on finger movement patterns. CSMP includes reliable encryption technologies such as Elliptic Curve Cryptography, the newest and fastest stream cipher SALSA20/20, SHA3-512 HASH, and more. The patent pending CrypID client-server authorization technology, along with the first Blockchain implementation in the scope of instant data exchange makes Crypviser the most secure communication solution on the market. A review of all the features offered by Crypviser shows that it is also a secure, all-around, private social network application capable of sending messages and multimedia files, voice, video, conference calls and sharing any kind of data. Businesses can get out of the network by utilizing the secure cloud-based PBX features, special widgets, and services. Vadim Andryan, CEO and Chief Architect of Crypviser, says, “These kinds of massive attacks mainly happen because employees do not care enough about their workplace security and often breach MDM/BYOD corporate policies. Using personal devices and even corporate communication platforms without providing the appropriate level of security for data exchange poses serious risks, allowing for information leakage and infection by malicious software.” “For instance, a popular communication app like Skype, installed on the working space could became a main source for the most serious security issues, as it is loved by hackers, allowing them to take control over user accounts and distribute malicious links through entire contact lists.” The Crypviser Network provides a secure ecosystem using automated encryption and authentication solutions based on Blockchain technologies. Cross-platform applications allow interconnected devices to exchange any kind of data without involving users in complex cryptographic processes. Crypviser utilizes the advantages of Blockchain to solve the biggest and most historical challenges of asymmetric cryptography - public key encryption. This means that as part of the heavily protected Crypviser system, users can get access to the network from any device, from anywhere, without worrying about their safety, any kind of “Man in the Middle” attacks, or "identity theft" issues.

A Cryptographic Compiler for Information-Flow Security
 
58:36
Joint work with Tamara Rezk and Gurvan le Guernic (MSR-INRIA Joint Centre http://msr-inria.inria.fr/projects/sec) We relate two notions of security: one simple and abstract, based on information flows in programs, the other more concrete, based on cryptography. In language-based security, confidentiality and integrity policies specify the permitted flows of information between parts of a system with different levels of trust. These policies enable a simple treatment of security, but their enforcement is delicate. We consider cryptographic enforcement mechanisms for distributed programs with untrusted components. Such programs may represent, for instance, distributed systems connected by some untrusted network. We develop a compiler from a small imperative language with locality and security annotations down to cryptographic implementations in F#. In source programs, security depends on a policy for reading and writing the shared variables. In their implementations, shared memory is unprotected, and security depends instead on encryption and signing. We rely on standard primitives and hypotheses for cryptography, stated in terms of probabilistic polynomial-time algorithms and games. Relying on a new type system, we show that our compiler preserves all information-flow properties: an adversary that interacts with the trusted components of our code and entirely controls its untrusted components gains illegal information only with negligible probability.

Fiat Cryptography: Automatic Correct-by-Construction Generation of Low-Level Cryptographic Code
 
01:05:21
Some of the most widely used cryptographic protocols, including TLS, depend on fast execution of modular big-number arithmetic. Cryptographic primitives are coded by an elite set of implementation experts, and most programmers are shocked to learn that performance-competitive implementations are rewritten from scratch for each new prime-number modulus and each significantly different hardware architecture. In the Fiat Cryptography project, we show for the first time that an automatic compiler can produce this modulus-specialized code, via formalized versions of the number-theoretic optimizations that had previously only been applied by hand. Through experiments for a wide range of moduli, compiled for 64-bit x86 and 32-bit ARM processors, we demonstrate typical speedups vs. an off-the-shelf big-integer library in the neighborhood of 5X, sometimes going up to 10X. As a bonus, our compiler is implemented in the Coq proof assistant and generates proofs of functional correctness. These combined benefits of rigorous correctness/security guarantees and labor-saving were enough to convince the Google Chrome team to adopt our compiler for parts of their TLS implementation in the BoringSSL library. The project is joint work with Andres Erbsen, Jade Philipoom, Jason Gross, and Robert Sloan.  See more at https://www.microsoft.com/en-us/research/video/fiat-cryptography-automatic-correct-by-construction-generation-of-low-level-cryptographic-code/

PCI Requirement 3.6.8 Key-Custodian Responsibilities
 
02:12
Key-custodians are one of the most important jobs within your organization. They’re responsible for creating encryption keys, altering keys, recovering keys, rotating keys, distributing keys, maintaining keys, and so much more. They are managing every aspect of the encryption of your environment. Key-custodians have the keys to your kingdom. By having key-custodians sign a formal document stating that they understand and accept their responsibilities, there is a better change for them to commit to their role. Your key-custodians must understand the gravity of the job they’ve taken, and assessors need to see some type of acknowledgement of that. If key-custodians do not perform their job correctly or securely, this affects your entire organization because it could lead to vulnerabilities and breaches. Watch the full video to learn more about PCI Requirement 3.6.8 from Jeff Wilder. If you store, process, or transmit cardholder data, interact with payment card data in any way, or have the ability to impact someone else’s cardholder information or the security of that information, you are subject to comply with the PCI DSS. This exclusive video series, PCI Demystified, was developed to assist your organization in understanding what the Payment Card Industry Data Security Standard (PCI DSS) is, who it applies to, what the specific requirements are, and what your organizations needs to know and do to become compliant. Learn more at https://kirkpatrickprice.com/video/pci-requirement-3-6-8-key-custodian-responsibilities/ Video Transcription Somebody needs to be truly responsible for managing the encryption of your environment. The individuals we typically identify as your key-custodians. These individuals need to sign a document – this signature can be electronic or it can be in writing – but effectively what we’re needing is some acknowledgment by these individuals that they truly understand the gravity of the job they’ve taken, and that they understand all of the policies and procedures and are good with it. The purpose and intent behind this is understanding that these individuals really have the keys to your kingdom. Their job, in my professional opinion, is one of the most important jobs in your environment. If they do not do their job well, or do not do it correctly or securely, that could effectively lead to the compromise of your environment. We’ve all seen what breaches in the past have done to organizations. From an assessment perspective, the assessor is going to be working with your HR department to identify who are those individuals responsible for the key management. We’re going to be asking for some artifact where they have read and understand their responsibilities as key-custodians in your environment.
