Abstract:
A method of encrypting a message for message integrity is provided. In the method, a random number is generated, a first ciphertext is generated by encrypting the message by using the generated random number, a hash value of the first ciphertext is calculated, an encryption key is generated by using the hash value of the first ciphertext and a shared key, a second ciphertext is generated by encrypting the random number by using the encryption key, and the first and second ciphertexts are combined.
