Title:
EM-Side-Channel Resistant Symmetric-Key Authentication Mechanism for Small Devices
Authors: Rick Boivie, Charanjit S. Jutla, Daniel Friedman, Ghavam Shahidi
Abstract:We provide a novel electro-magnetic (EM) side-channel resistant symmetric-key authentication mechanism for small devices that uses a Benes network to permute the on-board authentication-key before computing a MAC of a challenge with the key. The permutation itself is derived from the challenge using a hash function acting as a random oracle. The solution has interesting applications such as forgery detection of currency bills.
