DESCRIPTION:The Atomic Cryptographic Extension (ACE) is an ISA extension to
  enable secure cryptographic implementations. ACE separates key provisioni
 ng from key usage\, enabling distinct environments to perform the two func
 tions. For example\, keys could be delivered to user software by a TEE app
 let. Unlike existing round-based AES extensions\, which inherently expose 
 key material\, ACE performs cryptographic operations atomically. Keys are 
 associated with metadata that ties them to specific algorithms and usage p
 olicies. Keys and metadata are bonded to each other by writing them in Con
 text Registers (CRs). The contents of CRs can only be exported in encrypte
 d and authenticated form for secure re-import\, enabling secure context sw
 itches and VM migrations. ACE is work in progress of the High Assurance Cr
 yptography (HAC) TG of RISC-V International.
