Linux Cryptographic Acceleration on an i.MX6

Explore cryptographic acceleration on the i.MX6 platform in this 47-minute conference talk by Sean Hudson from Mentor Graphics, Inc. Delve into the process of enabling the CAAM (Cryptographic Accelerator and Assurance Module) on the i.MX6 SoC, addressing the critical need for robust encryption in IoT devices. Learn about various methods to connect userspace to the CAAM and compare their relative performance. Gain insights into cryptography basics, random number generation, and different implementation approaches, including Crypto API, CryptoDev, and OpenSSL plugin development. Examine the impact on CPU utilization and overall system performance when leveraging hardware acceleration for cryptographic operations.
