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. Several public key cryptosystems with additional homomorphic properties have been proposed so far. They allow to perform computation with encrypted data without the knowl...

Fair exchange turns out to be an increasingly importanttopic due to the rapid growth of electronic commerce. An exchange is deemed to be fair if at the end of exchange, either each...
The Diffie-Hellman key exchange algorithm can be implemented using the group of points on an elliptic curve over the field F2n. A software version of this using n = 155 can be o...

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...
