7 Conclusion

Based on the benchmarks presented in this application report for the various cryptographic functions, with and without using cryptographic accelerators, it is evident that the cryptographic accelerators integrated in SimpleLink CC13x2/CC26x2 Wireless MCUs speed up cryptographic operations and enable energy-efficient security solutions.

With security for network connected devices being critical, most systems are required to support security solutions such as network communication security, secure boot, and secure firmware updates. Embedded systems designers should review their application security requirements and associated cryptographic functions to determine if cryptographic accelerators and their performance can help meet the latency and energy consumption requirements in their systems.
