摘要: 结合代理签名和可转换认证加密两种方案,提出了代理可转换认证加密方案和(t,n)门限代理方案。方案能够使一个代理人代理被代理人认证加密一个消息给某个特定的接收者。

关键词: 公钥密码, 认证加密方案, 代理数字签名

Abstract: Combining proxy signature and convertible authenticated encryption scheme together,a proxy convertible authenticated encryption scheme and a(t,n) threshold were proposed,which could make a proxy signer/at least t of n proxy signers delegating an original signer authenticatedly encrypt a message to a designated receiver.

Key words: public key cryptology, authenticated encryption scheme, proxy digital signature
