A New SDV Anonymous Proxy Signature Scheme

In this paper, we firstly introduce the concept of anonymous proxy into the strong designated verifier signature scheme, and propose a new scheme named strong designated verifier anonymous proxy signature scheme. It is constructed by the NTRUSign signature algorithm whose security is based on the hardness of closest vector problem (CVP). We analyze the security of this scheme in great details and conclude that it has the characters of both anonymous proxy and strong designated verifier signature schemes. Therefore, it is believed that the new scheme will have a bright future.
