An efficient FPGA implementation of AES-CCM authenticated encryption IP core

Abstract

This paper presents an efficient AES-CCM IP core by combining a compact 8-bit AES encryption core and iterative structure. The AES-CCM core is used for message security at the MAC level, e.g. message authentication and encryption, based on AES forward cipher function for 128-bit keys operating with counter mode and cipher block chaining mode. The implementation results on FPGA show that the proposed AES-CCM core has higher resource usage efficiency compared with other designs.
