## For improving proxy-signature research, Sun [5] attempted to resolve problems related to defective security in the scheme of Yi [3]. However, both Yi and Sun's schemes involve a significant number of exponential operations to verify the proxy signature. Accordingly, an improvement is proposed her
In a multi-proxy signature scheme, an original signer could authorize a proxy group as his proxy agent. Then only the cooperation of all the signers in the proxy group can generate the proxy signatures on behalf of the original signer. Recently, Cao and Cao gave the first formal definition and secur
