摘要
针对近期提出的基于身份强指定验证者签名方案的安全漏洞,通过采用在随机Oracle模式安全的知识的零知识证明方法,构建一个安全的基于身份的强指定验证者签名方案。同时与以往体制相比,实现效率有明显提高。
There are some security flaws on certain identity-based strong designated verifier signature schemes proposed in recent years.Using the zero-knowledge proofs of knowledge upon a random oracle model,it is enabled to build a secure identity-based strong designated verifier signature scheme which is obviously higher at implementation efficiency.
