Abstract :
The key authentic degree of cryptosystem under the threat of the rubber-hose attack and ciphertext only attack is discussed. The foregoing cryptosystem of low key authentic degree is analyzed and its weakness is pointed out. An improved cryptosystem is given by changing the format the key and the encryption parameter. The cryptosystem is like multiple-choice questions. It is easy to find spurious keys of the cryptosystem that can confuse and mislead cryptanalysts according to the need.
