struct nbft_security - Security Profile Descriptor (Figure 21)

structure_id Structure ID: This field shall be set to 5h (i.e., Security; #NBFT_DESC_SECURITY). index Security Profile Descriptor Index: This field indicates the number of this Security Profile Descriptor in the Security Profile Descriptor List. flags Security Profile Descriptor Flags, see enumnbft_security_flags. secret_type Secret Type, see enumnbft_security_secret_type. reserved1 Reserved. sec_chan_alg_obj Secure Channel Algorithm Heap Object Reference: If the Security Policy List field is set to 1h, then this field indicates the location and size of a heap object containing a list of secure channel algorithms. The list is an array of bytes and the values are defined in the Security Type (SECTYPE) field in the Transport Specific Address Subtype Definition in the NVMe TCP Transport Specification. If the Security Policy List field is cleared to 0h, then this field is reserved. auth_proto_obj Authentication Protocols Heap Object Reference: If the Authentication Policy List field is set to 1h, then this field indicates the location and size of a heap object containing a list of authentication protocol identifiers. If the Authentication Policy List field is cleared to 0h, then this field is reserved. cipher_suite_obj Cipher Suite Offset Heap Object Reference: If the Cipher Suites Restricted by Policy bit is set to 1h, then this field indicates the location and size of a heap object containing a list of cipher suite identifiers. The list, if any, is an array of bytes and the values are defined in the IANA TLS Parameters Registry. If the Cipher Suites Restricted by Policy bit is cleared to 0h, then this field is reserved. dh_grp_obj DH Groups Heap Object Reference: If the Authentication DH Groups Restricted by Policy List bit is set to 1h, then this field indicates the location and size of a heap object containing a list of DH-HMAC-CHAP Diffie-Hellman (DH) group identifiers. If the Authentication DH Groups Restricted by Policy List bit is cleared to 0h, then this field is reserved. sec_hash_func_obj Secure Hash Functions Offset Heap Object Reference: If the Secure Hash Functions Policy List bit is set to 1h, then this field indicates the offset in bytes of a heap object containing a list of DH-HMAC-CHAP hash function identifiers. The list is an array of bytes and the values are defined in the NVM Express Base Specification. If the Secure Hash Functions Policy List bit is cleared to 0h, then this field is reserved. sec_keypath_obj Secret Keypath Offset Heap Object Reference: if this field is set to a non-zero value, then this field indicates the location and size of a heap object containing a URI. The type of the URI is specified in the Secret Type field. If this field is cleared to 0h, then this field is reserved. reserved2 Reserved. August 2025 struct nbft_security libnvme(2)
