Research on the Implementation of the AES-CCM Security Mode in a High Data-Rate Modem

In high data-rate communication systems, encryption/decryption must be processed in high speed. In this paper, we implement CCM security mode which is the basis of security. Specifically, we combine CCM with AES block encryption algorithm in hardware. With the combination, we can carry out encryption/decryption as well as data transmission/reception simultaneously without reducing data-rate, and we keep low-power consumption with high speed by optimizing CCM block.
