High speed AES256-GCM core implements the Advanced Encryption Standard (AES) in Galois Counter Mode (GCM). AES-GCM is a widely used cryptographic algorithm for Authenticated Enryption with Associated Data (AEAD) purposes, as it provides both data confidentiality and authenticity. XIP1113H has been designed for easy integration with FPGA- and ASIC-based designs in a vendor-agnostic design methodology, providing both data confidentiality and authenticity.
