Enhanced OpenSSL on i.MX 8M and i.MX 8MM
●Purpose:
■In embedded processor design the need of hardware support for cryptographic operations is increasing. In particular, there are customer requirements for easily performing cryptographic operations inside TrustZone®. In i.MX 8M and i.MX 8MM, OP-TEE OS can control the hardware cryptographic module by using libimxcrypt. This is a mechanism to perform hardware accelerated cryptographic operations inside of a secure zone.
■The purpose of this document is to describe how to add the support of accelerated OP-TEE OS with Cryptographic Accelerator and Assurance Module (CAAM) on top of OpenSSL. The final result being an enhanced OpenSSL being capable to accelerate crypto algorithms in a secure way via OP-TEE.
●Audience:
■This document is intended for those who:
▲Need to understand the secure storage inside of OP-TEE
▲Need to hardware accelerate cryptographic algorithms using the complete flow OpenSSL <-> OP-TEE <-> CAAM
■It is assumed that the reader is familiar with the basics of the RSA/ECC cryptographic functions.
