产品描述
The AES-CCM encryption IP core implements Rijndael encoding and decoding in compliance with the NIST Advanced Encryption Standard. It processes 128-bit blocks, and is programmable for 128-, 192-, and 256-bit key lengths.
Two architectural versions are available to suit system requirements. The Standard version (AES32-CCM) is more compact, using a 32-bit datapath and requiring 44/52/60 clock cycles for each data block (128/192/256-bit cipher key, respectively). The Fast version (AES128-CCM) achieves higher throughput, using a 128-bit datapath and requiring 11/13/15 clock cycles for each data block.
CCM stands for Counter with CBC- MAC mode. CCM is a generic authenticate-and-encrypt block cipher mode. CBC-MAC is utilized to generate an authentication string while CTR mode is used to encrypt.
