FPGA implementation and DPA resistance analysis of a lightweight HMAC construction based on photon hash family

Description

Lightweight security is currently a challenge in the field of cryptography. Most of applications designed for embedded scenarios often focus on authentication or on providing some form of anonymity and/or privacy. A well-known cryptographic element employed to provide such security is the HMAC construction. However, reported solutions are not suitable for constrained-resource scenarios due to their heavy approaches optimized for high-speed operations. In order to cover this lack, a lightweight implementation of HMAC based on the Photon family of hash functions is given in this work. Security of the construction against differential power attacks (DPA) is analyzed using a SASEBO-II development board. Implementation and performance results for Xilinx Virtex-5 FPGAs of the HMAC structure is provided
