This paper provides a comprehensive treatment of forward-security in the context of sharedkey based cryptographic primitives, as a practical means to mitigate the damage caused by...
A fair blind signature scheme allows the trustee to revoke blindness so that it provides authenticity and anonymity to honest users while preventing malicious users from abusing th...
Abstract. The study of minimal cryptographic primitives needed to implement secure computation among two or more players is a fundamental question in cryptography. The issue of com...

Abstract. Naor and Pinkas introduced metering schemes at Eurocrypt ’98 in order to decide on advertisement fees for web servers. In the schemes, any server should be able to cons...
Verifiable Signature Sharing (VS ) enables the recipient of a digital signature, who is not necessarily the original signer, to share such signature among n proxies so that a subse...
