We propose a zero-knowledge interactive proof based identification and signature scheme. The protocol is based on Euler's totient function and discrete logarithms over the ri...
Signcryption, first proposed by Zheng [4,5], is a cryptographic primitive which combines both the functions of digital signature and public key encryption in a logical single step,...
The strongest standard security notion for digital signature schemes is unforgeability under chosen message attacks. In practice, however, this notion can be insufficient due to ...

Abstract. We propose a variant of the “bonsai tree” signature scheme, a latticebased existentially unforgeable signature scheme in the standard model. Our construction offers ...
Various schemes have been proposed to achieve strong authenticationof streamed data in a lossy network by means of “light” digital signatures. Such techniques perform a strong...
