We introduce a new cryptographic tool: multiset hash functions. Unlike standard hash functions which take strings as input, multiset hash functions operate on multisets (or sets). ...

Cryptographic hash functions are often built on block ciphers in order to reduce the security of the hash to that of the cipher, and to minimize the hardware size. Proven secure co...

Cryptographic algorithms implemented on smart-cards must be protected against side-channel attacks. Some encryption schemes and hash functions like IDEA, RC6, MD5, SHA-1 alternate ...

We investigate several previously suggested scenarios of instantiating random oracles (ROs) with “realizable” primitives in cryptographic schemes. As candidates for such “in...

RSA-FDH and many other schemes secure in the Random-Oracle Model (ROM) require a hash function with output size larger than standard sizes. We show that the random-oracle instanti...
