Research and Application of Side Channel Attacks and Defenses on Embedded Systems

In mobile communication systems, channel attack and defense have always been one of the most important and highly concerned topics in the field of wireless interference technology research and application. In the current environment, all types of communication equipment face threats to varying degrees. This article is dedicated to analyzing and discussing how to use side channels for wireless signal transmission and data collection, and also proposes various methods based on error recovery technology, multiplexers, etc. to deal with possible data loss and damage problems in mobile terminals. By evaluating the transmission rate, security and other factors of the sending and receiving ends, the signal source can be determined whether it exists. Finally, through system testing experiments, it was verified that the trace number range of the original method was 156-176, while the trace number range of the advanced encryption standard algorithm was 134-153; the training accuracy of the original method was within 64%-79%, while the training accuracy of the Advanced Encryption Standard algorithm was within 80%-91%; the side channel isolation capability of the original method was within 0.63-0.69, while the side channel isolation capability of the Advanced Encryption Standard algorithm was within 0.84-0.93. Comprehensive experimental results show that the Advanced Encryption Standard algorithm performs very well in all aspects.
