Abstract: This paper proposes a proxy ring signature scheme based on multilinear mapping. This scheme can prevent the original signer from generating signature for message as a proxy signer and prevent the key generation center from forging proxy ring signature by introducing several key generation centers. The signature private keys of signer are completed by several key generation centers. Performance analysis results show that the scheme is feasible and secure.

Key words: digital signature, proxy signature, ring signature, multilinear mapping

摘要： 提出一种基于多线性映射的代理环签名方案。该方案能防止原始签名者冒充代理签名者对消息进行签名，通过引入多个密钥生成中心防止其中任何一个对消息进行签名。签名者的签名私钥由多个密钥生成中心共同决定。性能分析结果验证了该方案的可行性和安全性。
