This application note introduces IEEE 802.15.4 security and gives practical examples using Texas Instruments’ family of IEEE 802.15.4 compliant RF chipsets; the CC2420, CC2430 and CC2520. The main focus will be on the CC2520, TI’s second-generation IEEE 802.15.4 compliant RF transceiver. This document will also explain how to implement CCM mode on the CC2430 and CC2420 with the use of auxiliary software.
The application note is accompanied by a software example which implements a secure point to point link between two IEEE 802.15.4 compliant RF nodes, using MAC Data frames. The example demonstrates CCM security mode on all three chipsets, using a common RF protocol; BasicRF. This protocol implements a small part of the IEEE 802.15.4 specification, including a subset of the IEEE 802.15.4 security suite. This document is NOT a general discussion on security and AES.
