1.1. About the Cortex-A53 processor Cryptography Extension

The Cortex-A53 processor Cryptography Extension supports the ARMv8 Cryptography Extensions. The Cryptography Extensions add new A64, A32, and T32 instructions to Advanced SIMD that accelerate Advanced Encryption Standard (AES) encryption and decryption, and the Secure Hash Algorithm (SHA) functions SHA-1, SHA-224, and SHA-256.


The optional Cryptography Extension is not included in the base product. ARM supplies the Cryptography Extension only under an additional licence to the Cortex-A53 processor and Advanced SIMD and Floating-point support licences.
