On High-Rate Cryptographic Compression Functions
Abstract. The security of iterated hash functions relies on the properties of underlying compression functions. We study highly efficient compression functions based on block ciphe...

A fast real-time memory authentication protocol
We propose a new real-time authentication scheme for memory. As in previous proposals the scheme uses a Merkle tree to guarantee dynamic protection of memory. We use the universal...

On Provably Secure Time-Stamping Schemes
Abstract. It is almost a folklore-knowledge that hash-based time-stamping schemes are secure if the underlying hash function is collisionresistant but still no rigorous proofs have...

Second-Preimage Analysis of Reduced SHA-1
Many applications using cryptographic hash functions do not require collision resistance, but some kind of preimage resistance. That's also the reason why the widely used SHA-...
