Abstract :
Proxy blind signature technology integrates the properties of both the blind signature and proxy signature; it can be adopted in applications such as e-cash or e-commerce, etc. In 2008, Yang and Yu proposed an effective proxy blind signature scheme. It not only possesses the security properties of both blind signature and proxy signature, but also progresses in efficiency. Nevertheless, in signature generation phase, the receiver can forge the legal proxy signature without the authorization signatures of original signer and proxy signer. In this paper, we will propose an enhancement scheme to protect from being attacked with forgery. In addition, under the same computation cost, we construct the signature security infrastructure on the difficulty degree of solving discrete logarithm problems (DLP) which result in more perfected security.
