Cryptanalysis of an Efficient Deniable Authentication Protocol Based on Generalized ElGamal Signature Scheme
並列摘要
In 1998, Dwork et al. first proposed an application of zero-knowledge, deniable authentication protocol. Thereafter, there were many researches about the deniable authentication schemes. In 2004, Shao demonstrated out that the previous schemes had a common weakness in which any third party can impersonate the intended receiver to verify the signature of the given message, and they proposed a new scheme based on ElGamal signature scheme. Although Shao claimed that his scheme could provide complete security and properties of a deniable authentication scheme, we will point out that Shao's scheme is unable to achieve the second requirement of the deniable authentication scheme.
