摘要
The present invention relates to an encryption method for maintaining the integrity of the message, the present invention generates a random number and , using the generated random number to encrypt a message, it generates a first cipher text, and calculates a hash value of the first ciphertext, and using a hash value of the first ciphertext and the predetermined shared key to generate an encryption key, and the encryption key After generating a second ciphertext by encrypting the random number by using, by combining the first ciphertext and the second ciphertext, there is an effect that can not be broken integrity of the encrypted message, re-use. ; integrity, encryption, decryption, message and data
