Abstract
Mambo et al. (1996) discussed the delegation of signature power to a proxy signer. Lee et al. (2001) constructed a strong non-designated proxy signature scheme in which the proxy signer had strong non-repudiation. In this paper, we present an enhancement to their scheme such that the identity of the proxy signer is hidden behind an alias. The identity can be revealed only by the alias authority. We also discuss other applications of this technique.
