Fast inversion in GF(2m) with polynomial basis using optimal addition chains

2017

Inversion over GF(2m) is crucial for cryptographic applications such as elliptic curve cryptography. The commonly used Itoh-Tsujii algorithm (ITA) computes the inversion by an entirely sequential process consisting of multiplications and squarings. In this paper, …

High throughput AES encryption/decryption with efficient reordering and merging techniques

2017

This paper proposes a high throughput architecture for AES encryption/decryption targeting on the recent FPGAs with 6-input LUTs. Unlike previous works which share multiplicative inverse logics to realize SubBytes and InvSubBytes, the proposed architecture directly …
