hash-function tagging (SHAFT; =-=Zhang et al. 2006-=-). SHAFT utilizes the vertex-position label to design a compact, collision-free hash table, thereby avoiding the degradation of cache utilization for large graphs. The graph abstraction is also used t......
A well-designed hash function, h, distributes those integers so that few strings produce the same hash value. To build a hash table, the programmer uses the hash value of a string, modulo the table size, as an index into a table. Handling collisions is a key issue in hash table ...
ESRonce asked a friend what he expected Berkeley to be like. The friend replied, "Well, I have this mental picture of naked women throwing Molotov cocktails, but I think that's just a collision in my hash tables." This article is provided by FOLDOC - Free Online Dictionary of Computing ...
摘要: The FFT Hashing Function proposed by C.P. Schnorr [1] hashes messages of arbitrary length into a 128-bit hash value. In this paper, we show that this function is not collision free, and we give an exa关键词:18F-FLT tumor microPET ...
In this paper, we present new techniques for collision search in the hash function SHA-0. Using the new techniques, we can find collisions of the full 80-s... X Wang,H Yu,YL Yin - International Cryptology Conference 被引量: 1220发表: 2005年 Finite strain calculations of continental deform...

the best being a preimage attack for the first 33 steps of the hash function with complexity 2124.5. In this work, we provide a new assessment of the security margin of RIPEMD-128 by showing attacks on up to 48 (out of 64) steps of the hash function. We present a collision attack red...
Chameleon-hash functions, introduced by Krawczyk and Rabin (NDSS’00), are trapdoor collision-resistant hash functions parametrized by a public key. If the corresponding secret key is known, arbitrary collisions for the hash function can be found efficiently. Chameleon-hash functions have prominent ap...
