AES-CCM IMPLEMENTATIONS FOR THE IEEE 802.15.4 DEVICES

Recently, it has been suggested that the communication data exchanged by the IEEE 802.15.4 devices can be protected with the security services of confidentiality and integrity offered by the AES-CCM mode of operation. However, the typical type of devices implementing that standard present severe levels of computing constrains such as, computing power, memory space, and power drain, causing that the implementation of security services on such devices is frequently a challenge not easy to meet. In this paper we present a study of the hardware cost associated with the implementation of AES-CCM in reconfigurable hardware devices. Copyright © 2007 IFAC
