ES-GCM/CCM/CCM*/EAX' Core

Overview

The GCE1-MP core implements Rijndael encoding and decoding in compliance with the NIST Advanced Encryption Standard and encryption/authentication modes GCM, CCM, CCM*, and EAX’. It processes 128-bit blocks using 128-bit keys.

GCE1-MP core is a configuration of the GCE1 core that includes a 128-bit internal key. The register-based interface of the core of the core allows its easy integration into a microprocessor system.

The design is fully synchronous and is immediately available in Verilog (optional VHDL).

Key Features

Completely self-contained: does not require external memory
Supports both encryption and decryption
Includes AES key expansion and mode processing.
128 bit AES key, IV, counter, tag storage
SRAM-like interface design for 8-bit and 32-bit buses
Test bench provided
