Self-certified Proxy Signcryption Based on Discrete Logarithm Problem
Wang Xiao-hong · 2010
Self-certified cryptosystem realizes the properties of no public key certificate and key-unescrow,proxy signcryption is a scheme that combines the proxy signature and signcryption.By merging the thoughts of self-certified cryptosystem and proxy signcryption,a new self-certified proxy signcryption scheme based on discrete logarithm problem was proposed on the basis of the existing literatures.Under the hardness of discrete logarithm problem in finite field,the new scheme was proved to be correct and secure.
