A New Publicly Verifiable Proxy Signcryption Scheme
Zhang Zhang, Qingkuan Dong, Cai Mian · Kluwer Academic Publishers eBooks · 2006
Proxy signcryption scheme is the combination of proxy signature and encryption. This paper presents a new proxy signcryption scheme based on Shin et al.’s DSA-verifiable signcryption Scheme. As compared to the previous schemes, the proposed scheme has the following advantages: it can protect the proxy signer against the original signer’s forgery attack; it can be publicly verified; it provides forward secrecy property with respect to the proxy signer.
