Security of Cyclic Double Block Length Hash Functions
2009We provide a proof of security for a huge class of double block length hash function that we will call Cyclic-DM . Using this result, we are able to give a collision resistance bound for Abreast-DM , one of the oldest and most well-known constructions for turning a block cipher with n -bit block length and 2n -bit key length into a 2n -bit ...

K-means based double-bit quantization for hashing
2014 IEEE Symposium on Computational Intelligence for Multimedia, Signal and Vision Processing (CIMSIVP), 2014Hashing function is an efficient way for nearest neighbor search in massive dataset because of low storage cost and low computational cost. However, it is NP hard problem to transform data points from the original space into a new hypercube space directly. Typically, the most of hashing methods choose a two-stage strategy. In the first stage, dimension
