The article compares the performance and memory requirements of AES-GCM and ChaCha20Poly1305 AED encryption solutions for typical 8/16/32-bit embedded low-end processors in the Internet of Things device with different approaches to providing tolerance to Timing Attacks and Simple Power Analysis Attacks. Particular attention is given to the low-level multiplication implementation in GF(2128) with constant execution time as a key GCM operation, since low-end processors do not have ready instructions for carry-less multiplication.
