¿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. |
