为了进一步改进现有的邮件加密算法的安全性,在椭圆曲线的密码体制的基础之上,本文提出一种兼顾安全和实用性的有序数字签名邮件加密算法,利用椭圆曲线的密码体制进行赋权而得以实现多重数字签名,在椭圆曲线离散对数的难题的基础之上保障多重数字签名的安全和可靠性。此外,采用这种算法,还可以缩短密码的长度,保证使用者的执行速度和效率。前瞻性的采用前向安全的设计概念可以将签名密钥泄露的风险和不确定性控制到最小,尽可能的消除了系统受到的波及。最后对方案的有效性详尽分析,仿真实验表明此方案是具有安全性、简单易上手的实用性的数字签名方案,实用价值较大。

In order to further improve the security of encryption algorithms existing mail, on the basis of the elliptic curve cryptosystem, this paper puts forward a kind of give attention to both security and practicability of ordered digital signature email encryption algorithm, using the elliptic curve cryptosystem to empowerment and be able to realize multi digital signature, the elliptic curve discrete logarithm problem based on the guarantee of safety and reliability of multiple digital signatures. In addition, this algorithm can also shorten the length of the password to ensure the speed and efficiency of users. Prospective to safety before the adoption of the design concept of signature key leaked risk and uncertainty can be controlled to a minimum, as far as possible to eliminate the system affected by the last to detailed analysis of the effectiveness of the scheme, the simulation experiments show that the scheme is safety, easy to fit practical digital signature scheme, the practical value is bigger.
