【摘要】 通过对密码加密过程及验证密码的分析,总结出了三个特点,利用其中最主要的第二个特点,即明文密码和密文密码 之间具有不可逆性,对应用软件密码进行加密,可以防止密码被破译或极大地增加了其被破译难度和破译时间。并初步探讨了增 强这种算法安全性的几种相关加密算法。同时对这种加密算法的明文密码空间、密文密码空间和加密强度等作了初步的分析。根 据分析可以看出这种加密算法具有很高的加密强度。更多还原

【Abstract】 This paper summarizes three features of encryption by analyzing the procedure of cipher encryption and authentication. The second feature that is the most important one—the irreversibility between plaintext and ciphertext—is used to encrypt the cipher of application software. Therefore the decryption time and difficulty can be greatly increased, and the cipher can be protected from decryption in this algorithm. The paper also tentatively discusses several related encryption algorithms to improve the security and analyzes the plaintext key space, ciphertext key space and encryption strength. The analyses confirmed that the strength of this encryption algorithm is commendable.更多还原
