Abstract :
The article proposes an Online/Off-line Ring Signature Scheme in random oracle model. Security of the scheme relies on both Computational Diffie-Hellman and k-CAA problems. In Online/Off-line signature scheme. The proposed scheme is secure against Existential Unforgeability. It has Signer Ambiguity and robustness property where the misbehavior of the signer can be detected.
