Hashing-based recommender systems that represent users and items as binary hash codes are recently proposed to significantly improve time and space efficiency. However, the highly developed social ...

A hash function based on sponge structure with chaotic mapping (SSCM) algorithm is designed for spinal codes to degrade high time complexity. The internal permutation function of the designed hash ...

SHA-1, Secure Hash Algorithm 1, a very popular cryptographic hashing function designed in 1995 by the NSA, is officially dead after a team of researchers from Google and the CWI Institute in Amsterdam ...
