A Secure ID Based Group Signature Scheme Based on Factoring and Discrete Logarithm Problem
Pankaj Sarde, Amitabh Banerjee, Chandrashekhar Dewangan · Journal of Applied Security Research · 2017
Group signature scheme allows group members to sign an arbitrary number of messages on behalf of the group without revealing their identity. In case of dispute, the group manager holding a tracing key can reveal the identity of the signer from the signature. Tseng-Jan (Tseng & Jan, 1998) proposed a novel ID-based group signature scheme which is unforgeable. In this article we propose a secure ID-based group signature scheme based on factoring and discrete logarithm problem. Our Scheme is more secure as compared to Tseng-Jan group signature scheme.
