To enhance applications of smart cards, Miyazaki and Takaragi proposed a (t, n) threshold digital signature scheme based on the security of elliptic curve discrete logarithm (ECDL...
We propose in this paper a new voting scheme where the voter, while receiving a receipt for his/her vote allowing further contestations, cannot use it to reveal the vote to other u...
In a blind signature scheme, the user can get a signature sig(m) on message m generated from the signer's blind signature sig(m ) on blinded message m , but the signer can...
This paper investigates some modular powering functions suitable for cryptography. It is well known that the Rabin encryption function is a 4-to-1 mapping and breaking its one-wayn...
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...
