¿µ¹®³»¿ë¿ä¾à CCM is a generic authenticated encryption block cipher operation mode using 128-
bit block cipher. CCM uses the CBC-MAC (Cipher Block Chaining – Message
Authentication Code) mode for message authentication and CTR mode for message
confidentiality. This standard describes the procedure of massage authentication code
generation/verification and message encryption/decryption. Additionally, this standard
includes the security consideration.
