Abstract: The AVR family of 8-bit microcontrollers is widely used in several applications demanding secure communications and protection against physical attacks, such as side-channel analysis. In this context, processing, storage and energy demands of cryptographic software must be low, requirements which are met by ECC. At the 128-bit security level, two recently proposed curves are an attractive option for 8-bit microcontrollers: Curve25519 for Diffie-Hellman key exchange, and Ed25519 for signature. Simple power analysis is a significant threat to AVR applications, but efficient and side-channel tested implementations of SPA countermeasures for ECC protocols have not yet been dealt with in this platform, in the literature. This paper describes an efficient implementation of ECDH-Curve25519 and EdDSA-Ed25519-SHA512 for the ATmega328P platform. Our implementation provides protection against timing attacks, SPA and template SPA. The resistance against SPA is evaluated through the test vector leakage assessment (TVLA) methodology based on Welch's t-test, using the Chipwhisperer platform.
