High-Performance AES-GCM/CTR IP

Overview

The compact, high-performance Synopsys Pipelined AES-GCM/CTR Core implements the AES-GCM/CTR algorithm as specified in the National Institute of Standards and Technology (NIST) Special Publication 800-38D, “Recommendation for Block Cipher Modes of Operation: Galois/Counter Mode (GCM) and GMAC”. AES-GCM/CTR is the algorithm of choice for high- performance cryptographic systems. It uses Advanced Encryption Standard
(AES) algorithm in counter mode (CTR), and a high-performance MAC algorithm based on Galois Field multiplication with CTR mode encryption, which can be pipelined for high throughput operations.
