A communication apparatus performs encryption on data transmitted from another communication apparatus by using first or second cryptographic algorithm, or performs decryption on the data that has been encrypted using the first or second cryptographic algorithm, by using one of the first and second cryptographic algorithms used for the encryption, where the second cryptographic algorithm provides a higher security level than the first cryptographic algorithm. The communication apparatus includes an encryption unit configured to perform, upon receiving the data including a cryptographic class identifying a parameter to be used for performing the encryption or the decryption, the encryption or the decryption by using one of the first and second cryptographic algorithms, based on the cryptographic class.
