摘　　要：借鉴环签名的思想,提出了一个新的基于ECC(EllipticCurveCryptosystems)的匿名签密方案。该方案在普通签密方案已有特性基础上,进一步实现了签密者身份的完全匿名性,从而在最大程度上保护了签密者的隐私。这些特点使得本文方案可以应用于许多特殊场合,如雇员反馈系统。文中的方案基于椭圆曲线密码体制,具有较短的密钥长度而不失安全性,同时将数字签名与对称加密过程相结合,从而较传统的实现方法具有更高的效率。A new anonymous signcrption scheme based on ECC(Elliptic Curve Cryptosystems) was put forward,which was inspired by the idea of ring signature. While satisfying all the security properties proposed in previous signcrption schemes,the new scheme provided a new desired security property,complete-anonymity,which maked the privacy of user protected to the most degree. With all these features,this work was attractive for many specialized applications,such as employee feedback programs. Based on ECC,this scheme required shorter key without losing security. While simultaneously fulfilling both the functions of digital signature and symmetrical encryption in a single step,this scheme was more efficient than traditional two-step(signature-then-encryption) approach.
