摘要: PEM、PGP以及S/MIME虽然提高了电子邮件的安全性,但仍存在速度慢以及安全性不够等不足。该文在介绍了混沌的分组密码算法、二维超混沌的单向Hash函数以及混沌与椭圆曲线的数字签名算法的基础上,提出了一种新的安全电子邮件系统。分析和应用表明,该系统具较高的速度和良好的安全性,具有广泛的应用前景。

Abstract: PEM, PGP and S/MIME improve the security of E-mail, but problems such as low speed and lack of security still exist. A novel secure E-mail system is proposed to handle these problems. A block cipher based on chaotic maps, a one-way hash function based on two-dimension hyper-chaotic maps and a digital signature algorithm based on chaos and elliptic curves are introduced to construct the scheme. Analysis and application show that the system possesses good performance on operation speed and security, and it has great potential in practice.

Key words: secure E-mail, chaos, elliptic curves
