Abstract:
The paper brings out the concept of key authentic degree in the light of the rubber-hose attack and ciphertext only attack. At the same time, a new cryptosystem that has low key authentic degree is designed. When it is used to encrypt, it is easy to find pseudokeys that can confuse and mislead cryptanalyst.
Key words:

摘要: 针对软磨硬泡攻击和唯密文攻击等攻击,提出了密钥可信性的概念,设计了一种密钥可信度低的密码体制,应用该算法模型加密可以很容易得到伪密钥,从而可以误导和迷惑密码分析者。适合于高度机密、密钥容易被截获、密钥的存放没有安全保障、具有很强的运算能力或者对于速度要求不是非常高的情形。
