This paper presents a compact, ultra-low power AES-CCM authenticated encryption IP core for WBANs by combining a low area 8-bit AES encryption core, iterative structure and other optimized circuits. The proposed AES-CCM IP core can be used for the message security at the MAC level, e.g. message encryption and authentication, based on AES forward cipher function with a 128-bit key for counter and cipher block chaining modes of operations. The implementation results show that the proposed AES-CCM IP core achieves a very high resource efficiency and ultra-low power consumption while meeting the requirement of operation speed in WBANs.
