4.15. Crypto Engine

4.15.1. Overview

The Crypto Engine is one encrypt/ decrypt function accelerator. It is suitable for a variety of applications. It can support

encryption ,decryption and calculate the hash value. Several modes are supported by the Crypto Engine. The Crypto

Engine has a special internal DMA(IDMA) controller to transfer data .

It includes the following features:

 Support symmetrical algorithm :AES, DES, TDES

 Support secure Hash algorithm: MD5, SHA-1,SHA-224,SHA-256,SHA-384,SHA-512,HMAC-SHA1

 Support 160-bits hardware PRNG with 175-bits seed

 Support 256-bits hardware TRNG

 Support ECB, CBC, CTR modes for DES/TDES

 Support ECB, CBC, CTR, CTS,OFB,CFB,CBC-MAC modes for AES

 Support 128-bits, 192-bits and 256-bits key size for AES
