How to Formalize Loop Iterations in Cryptographic Protocols Using ProVerif
IEEE AccessThe formal verification of cryptographic protocols has been extensively studied in recent years. To verify the cryptographic protocol security, formal verification tools consider protocol properties as interactive processes involving a cryptographic ...

Using fuzzy bits and neural networks to partially invert few rounds of some cryptographic hash functions [PDF]
arXiv, 2019 We consider fuzzy, or continuous, bits, which take values in [0;1] and (-1;1] instead of {0;1}, and operations on them (NOT, XOR etc.) and on their sequences (ADD), to obtain the generalization of cryptographic hash functions, CHFs, for the messages consisting of fuzzy bits, so that CHFs become smooth and non-constant functions of each bit of the ...

On quantum preimage attacks [PDF]
arXiv, 2014 We propose a preimage attack against cryptographic hash functions based on the speedup enabled by quantum computing. Preimage resistance is a fundamental property cryptographic hash functions must possess. The motivation behind this work relies in the lack of conventional attacks against newly introduced hash schemes such as the recently elected SHA-3 ...

Analysis of cryptographic hash functions [PDF]
, 2012 The National Institute of Standards and Technology (NIST) launched in 2008 a public competition, called the SHA-3 competition, aiming at definining a new standard for hash functions. We study here the algebraic properties of some of the candidates to this contest. Among the functions analyzed, is the Keccak algorithm, which was recently announced to be

Collision-resistant hash function based on composition of functions [PDF]
ARIMA, Vol. 14 - pp. 167-183, 2011, 2011 cryptographic hash function is a deterministic procedure that compresses an arbitrary block of numerical data and returns a fixed-size bit string. There exist many hash functions: MD5, HAVAL, SHA, ... It was reported that these hash functions are not longer secure.
