摘要: We analyze the security of CTR + CBC-MAC (CCM) encryption mode. This mode, proposed by Doug Whiting, Russ Housley, and Niels Ferguson, combines ("counter") mode with message authentication is based on a block cipher such as AES. present concrete lower bounds for CCM in terms underlying cipher. The conclusion that provides level privacy authenticity line other modes OCB.
