Forward Secure Designated Verifier Signature Scheme with Message Recovery
Hui Zhang · 2010
Based on the study of designated verifier proxy blind signature scheme with message recovery,the paper proposes a forward secure designated verifier cooperative blind signature scheme with message recovery by combining the concept of forward security.In the scheme,the signature is completed by the signature sponsor and the signature partner in cooperation.The scheme can be realized even if all the signatures keys of signers are leaked,the attacker can not forge the signature of the previous stage,previous generated signature remains valid.
