摘　　要：在Hess签名方案的基础上,提出一个高效的基于身份的可验证加密签名方案.该方案具有较少对运算且仲裁者对自己的保证书签名,防止解决冲突时拒绝恢复普通签名,从而加强了交换签名的公平性.与类似的方案相比,该方案更高效.最后在随机预言模型中给出了安全证明.在CDHP是困难的假设下,该方案被证明是安全的.Based on the Hess signature scheme,an efficient id-based verifiably encrypted signature scheme was proposed.The scheme had the less pairing operations,and adjudicator signed a guarantee to avoid refusing to resume the common signature when resolving conflicts,thereby exchange signature protocol＇s equity was enhanced.Compared with the other schemes,the proposed scheme was more efficient.At last its security was proved in the random oracle model.The proposed scheme was proved to be secure assuming the computing Diffie-Hellman problem was hard.
