IOTA tutorial 8: Cryptographic sponge construction
 
07:10
If you like this video and want to support me, go this page for my donation crypto addresses: https://www.youtube.com/c/mobilefish/about This is part 8 of the IOTA tutorial. In this video series different topics will be explained which will help you to understand IOTA. It is recommended to watch each video sequentially as I may refer to certain IOTA topics explained earlier. In 2007, the sponge construction was introduced by Guido Bertoni and others. A sponge construction or sponge function takes input bit data of any length (message) and produce an output bit data of any desired length (hash digest). Simply said, the data is "absorbed" into the sponge, then the result is "squeezed" out.  The sponge function has two phases, the absorbing phase in which the message is compressed iteratively followed by the squeezing phase in which the hash digest is extracted in a iterative manner. A sponge function has three components: A state memory (S) which is divided into two sections: one of size r (the bitrate) and the other of size c (the capacity). For simplicity sake in this video the capacity will be complete ignored. A compression function (f) of fixed length that transforms the state memory. IOTA uses the Keccak-384 hash algorithm as its compression function. Please note this Keccak-384 hash algorithm does not comply with the standardised SHA3-384 as defined by the National Institute of Standards and Technology (NIST). A padding function (pad) which appends enough bits to the input data (M) so that the length of the padded input is a whole multiple of the bitrate r. The padded input can thus be broken into r-bit blocks. The sponge function operates as follows, starting with the absorbing phase: The state memory S is initialised to zero. The padded input is broken into r-bit blocks and called M0, M1, M2, etc. The r-bit block is XORed with the first message block M0 and the result is passed to the compression function f. The function stores its result in the state memory S. The updated r-bit block is XORed with the second message block M1 and the result is passed to function f. Again function f stores its result in the state memory S. The process is repeated until all message blocks M0, M1, M2 etc. are used up. The sponge function squeezing phase, to create the hash digest is as follows: The r-bit block of the state memory is the first r bits of output (Z0). If more output bits are desired the r-bit block is passed to function f. Function f stores its result in the state memory S. The r-bit block of the state memory is the next r bits of output (Z1). The process is repeated until the desired number of output bits are produced. The concatenated values Z0, Z1, Z2, etc, forms the hash digest. If the output length is not a multiple of r bits, it will be truncated.

Cryptographic hash function
 
20:12
A cryptographic hash function is a hash function which is considered practically impossible to invert, that is, to recreate the input data from its hash value alone. The input data is often called the message, and the hash value is often called the message digest or simply the digest. This video is targeted to blind users.

Professor Ivan Bjerre Damgård Presenting the Concordium Blockchain ID Layer
 
13:25
Professor Ivan Bjerre Damgård is a Researcher and Cryptography Lead at the CONCORDIUM BLOCKCHAIN RESEARCH CENTER at Aarhus University Professor Ivan Damgård holds a PhD in Computer Science from Aarhus University (1988). He is one of the top cited and published researchers in cryptography, fellow of the IACR and received the 2015 RSA Award for Excellence in the Field of Mathematics. He has managed numerous research projects and holds an advanced ERC grant. As is well known to the blockchain community at large, Professor Damgård is a co-inventor of the Merkle–Damgård-construction, which is the principal cryptographic hash function that every blockchain in existence relies upon in some form or another. He is a co-founder of Cryptomatic, a software and consultancy company in secure e-business as well as of the companies Partisia, Sepior and Secata. In 2017 Damgård was awarded the Villum Kann Rasmussen Annual Science and Technology Award, the most prestigious science award in Denmark. About Concordium Foundation: The Concordium Network is a proof-of-stake-based blockchain network that will be designed from the ground up to deliver a trustworthy and solid foundation for business. It will feature a protocol-layer ID/KYC mechanism that ensures that every user on the network is identified, and that every transaction involves provenance tracking. These features do not prevent the provision of privacy (based on zero-knowledge proofs), but they provide an environment that we believe will be acceptable to regulators, to public institutions, to financial institutions and to “big business,” while solving a number of key issues in blockchain-based transaction logging such as avoiding single points of failure and providing finality in transactions. With this initiative, the Concordium Foundation intends to address and improve various technical aspects of existing blockchains, but most importantly, it aims to provide a blockchain network that delivers a regulatable and compliant transaction logging, transaction settlement and transaction finalization environment while enabling a wide range of powerful and legitimate business applications through use of flexible smart contracts.

Alternative Sponge and Permuting Functions
 
09:30
The Enhanced Sponge Function (ESP) is constructed using two permutation functions. This is in contrast to using only one function as presented in the seminal paper on sponge functions by G. Bertoni et al. The use of only one function carries traces of Merkle-Damgard structure. The shuffling between two permuting functions is performed using a message-dependent pseudo-randomly generated key. Using two pseudo-randomly shuffled functions, providing a non-deterministic data path, increases the uncertainty or entropy in the sponge function output bits. We argue that the proposed construction, without any loss of generality, closely emulates a random oracle more than the original sponge structure using only one function.
