ID-based Strong Designated Verifier Signature Scheme
Shao Jian, Zhenfu Cao, Lifei Wei · Jisuanji gongcheng · 2010
An ID-based designated verifier signature is analyzed,which shows that anyone who intercepts one signature can verify subsequence signatures without need of receiver's private key.Another ID-based designated verifier signature based on one-pass Authenticated Key Exchange(AKE) is presented.This scheme has strong security properties such as the known key security and the forward security that are derived from the one-pass AKE.Compared with the existing schemes,the scheme is much more efficient in sign and verify algorithms.
