Value
Decryption KAD capable when Decryption Mode is Decrypt or Mixed
00b = Not specified (Not supported)
01b = Drive requires a U-KAD provided by the Host for decrypting
operations.
If not provided with SPOUT command Set Data Encryption page then
terminate the command with Check Condition with sense key set to
Illegal Request and the ASC set to Incomplete
Key-Associated Date Set.
10b = Not required (Not supported)
11b = Optional (Not supported)
External encryption mode capabilities
00b = Not supported
Raw decryption mode capable
001b = Raw decryption mode not supported
Encryption mode recorded
1 = Encryption mode is recorded with each logical block
Maximum supplemental decryption key count supported 00000000h =
Currently not supported
80010010h = ENCR_AES_CCM16 (RFC 4309)
Note – Advanced Encryption Standard—AES—is a block cipher
encryption algorithm that uses Counter with CBC-MAC (Cipher
Block Chaining–Message Authentication Code), or CCM, as a
mode of encryption that provides both a strong form of privacy
(security) and efficient authentication.
