We present a hardware architecture for an Elliptic Curve Cryptography System performing the three basic cryptographic schemes: DH key generation, encryption and digital signature....
Abstract. Field-Programmable Gate Arrays (FPGAs) have lately become a popular target for implementing cryptographic block ciphers, as a well-designed FPGA solution can combine some...
Abstract. In this paper, we first demonstrate a gap between the security of verifiably committed signatures in the two-party setting and the security of verifiably committed signat...
We construct a fully collusion resistant tracing traitors system with sublinear size ciphertexts and constant size private keys. More precisely, let N be the total number of users...
We present the first aggregate signature, the first multisignature, and the first verifiably encrypted signature provably secure without random oracles. Our constructions derive f...
