Looting the LUTs : FPGA Optimization of AES and AES-like Ciphers for Authenticated Encryption.
2017 · IACR Cryptology ePrint Archive
In this paper, we investigate the efficiency of FPGA implementations of AES and AES-like ciphers, specially in the context of authenticated encryption. We consider the encryption/decryption and the authentication/verification structures of OCB-like modes (like OTR …

Fiddling the Twiddle Constants - Fault Injection Analysis of the Number Theoretic Transform
2023 · IACR Transactions on Cryptographic Hardware and Embedded Systems
In this work, we present the first fault injection analysis of the Number Theoretic Transform (NTT). The NTT is an integral computation unit, widely used for polynomial multiplication in several structured lattice-based key encapsulation mechanisms …

Efficient Model Propagation for Peer-to-Peer Federated Learning using Minimum Spanning Tree and Gossip Networks
2025
Recently, Peer-to-Peer (P2P) Federated Learning (FL) algorithms have caught the attention of researchers due to their ability to extend classical FL through complete decentralization - thereby unlocking potentially new applications as well as addressing various …
