Digital Signatures Over HMAC Entangled Chains
Engineering Science and Technology, an International Journal, 2022 In this work we present a new digital signature method based on hash chains and the hash message authentication code (HMAC). Unlike Blockchain technology, our approach establishes that the database of transactions is distributed among users, so each one ...

Carry-based Differential Power Analysis (CDPA) and its Application to Attacking HMAC-SHA-2
Transactions on Cryptographic Hardware and Embedded Systems, 2023 In this paper, we introduce Carry-based Differential Power Analysis (CDPA), a novel methodology that allows for attacking schemes that use arithmetical addition. We apply this methodology to attacking HMAC-SHA-2. We provide full mathematical analysis of
