Abstract. We introduce VSH, very smooth hash, a new S-bit hash function that is provably collision-resistant assuming the hardness of finding nontrivial modular square roots of ver...
Abstract Two protocols for authentication based on symmetric key cryptography are described, where the verifier can be implemented in software completely, without the need for secu...
Abstract. We introduce Verifiable Signature Sharing (VCS), a cryptographic primitive for protecting digital signatures. VCS enables the holder of a digitally signed document, who m...
Abstract. The security challenges posed by RFID-tag deployments are wellknown. In response there is a rich literature on new cryptographic protocols and an on-tag hash function is ...
