From 0f1519439f5bff0608f4a24baaaed108a0d0be5c Mon Sep 17 00:00:00 2001 From: Jerome Forissier Date: Tue, 17 Dec 2019 09:19:56 +0100 Subject: core: crypto add support for SM2 DSA Adds SM2 Digital Signature Algorithm [1] using LibTomCrypt. The TA interface complies with the GlobalPlatform TEE Internal Core API version 1.2. SM2 DSA is enabled with CFG_CRYPTO_SM2_DSA=y (default y) which currently requires that CFG_CRYPTOLIB_NAME=tomcrypt. An Mbed TLS implementation could be added later if needed.
