Forward-Secure Threshold Signature Schemes
We consider the usage of forward security with threshold signature schemes. This means that even if more than the threshold number of players are compromised, some security remain...

Certificateless Group Oriented Signature Secure Against Key Replacement Attack
Since Al-Riyami and Paterson presented certificateless cryptography, many certificateless schemes have been proposed for different purposes. In this paper, we present a certificate...

Compact Group Signatures Without Random Oracles
We present the first efficient group signature scheme that is provably secure without random oracles. We achieve this result by combining provably secure hierarchical signatures i...

Security Analysis of Several Group Signature Schemes
At Eurocrypt’91, Chaum and van Heyst introduced the concept of group signature. In such a scheme, each group member is allowed to sign messages on behalf of a group anonymously. ...

On the Minimal Assumptions of Group Signature Schemes
Abstract. One of the central lines of cryptographic research is identifying the weakest assumptions required for the construction of secure primitives. In the context of group sign...
