ChaCha20 Intrinsics

    XMLWordPrintable

Details

    Description

      Create intrinsics for the ChaCha20 algorithm for x86_64 and aarch64. On x86_64, support for AVX, AVX2 and AVX-512 should be taken into account to support a wide array of x86 chips. For the aarch64 platform, a baseline ASIMD implementation should be created, with possible enhancements from the SVE instruction set for supporting processors.

      The current approach will accelerate the core 20-round ChaCha20 block function, as outlined in RFC 7539, section 2.3.
