摘　　要：针对自证明公钥密钥更新比较困难的问题,基于现有的椭圆曲线自证明公钥,提出一种用户更新自证明公钥生成算法。该算法实现用户自证明公钥的自主更新,通过分析表明,该用户更新自证明公钥可以减少密钥更新的计算开销与通信开销,更新后的公钥仍然具有自证明性,且能够提供自证明公钥的显式验证。To solve the key renewing problem of the self-certified public key, it proposes a user controlled key renew arithmetic of self-certified public key, which is based on ECC self-certified public key. User can renew the self-certified public key independently. It is analyzed that the proposed scheme can reduce the computation and communication costs of key renewing. The renewed key still has the self-certified attributes and can be verified explicitly.

关 键 词：自证明公钥 用户更新 显式验证
