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.
