AN060 - Security on TI IEEE 802.15.4 Compliant RF Devices
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, CC2520 and
CC2530. 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, CC2530 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.
The IEEE 802.15.4-2006 specification uses the abbreviation CCM* mode (Counter-Counter-Mode ‘Star’). The ‘*’ is thus not a footnote in this context.
