Mitigation best practices
Always build the latest TrustCore SDK release.
Follow NIST SP 800-131A Rev. 2 recommendations (disable legacy ciphers such as 3DES and RSA keys <2048 bits) and be aware of upcoming guidance like NIST SP 800-131A Rev. 3.
Enable compiler flags that enforce constant-time crypto (
enable-vlong-const,--fips-700-compat, etc.).
