密码体制的密钥可信度探讨

Discussion On Key Authentic Degree of Cryptosystem

该文对密码体制的密钥可信度进行了详细阐述,指出了研究密钥可信度的重要意义,并且给出了在不同的条件下现代密码体制的密钥可信度。研究表明,绝大多数情况下,虽然,密钥可信度都是很高的,但是现代密码体制很容易受到软磨硬泡之类的攻击的威胁。该文还分析了低密钥可信度的密码算法的可行性,并且对实现低密钥可信度密码算法进行了研究。

Against such attacks as rubber-hose attack,key authentic degree of cryptosystem is expatiated,and the important significance of key authentic degree of cryptosystem is pointed out. The key authentic degrees of modern cryptosystem under different conditions are given. Research shows under most realistic situations the key authentic degree of modern cryptosystem is high,this means that modern cryptosystem is vulnerable to such attacks as rubber-hose attack. Feasibility analysis of designing cryptosystem of low key authentic degree is made,the implementing of cryptosystem of low key authentic degree is studied.
