◆ SecurityBlockType

Security Block Type values as defined by OSDP protocol.

Enumerator
BeginNewSecureConnectionSequence	SCS_11 - Sent along with osdp_CHLNG command when ACU initiates a secure channel connection.
SecureConnectionSequenceStep2	SCS_12 - Sent along with osdp_CCRYPT message in response to osdp_CHLNG command.
SecureConnectionSequenceStep3	SCS_13 - Sent along with osdp_SCRYPT command as the third step of secure channel handshake.
SecureConnectionSequenceStep4	SCS_14 - Sent along with osdp_RMAC_I message in response to ACU's osdp_SCRYPT message. This is the final step in secure channel handshake. Once this is received by ACU, the secure channel is established on both sides
CommandMessageWithNoDataSecurity	SCS_15 - ACU -> PD; secure channel is established and the command message contains a MAC signature but the data field is unencrypted.
ReplyMessageWithNoDataSecurity	SCS_16 - PD -> ACU; secure channel is established and the reply message contains a MAC signature but the data field is unencrypted.
CommandMessageWithDataSecurity	SCS_17 - ACU -> PD; secure channel is established. The command message contains a MAC signature and the data field is encrypted using the S-ENC key
ReplyMessageWithDataSecurity	SCS_18 - PD -> ACU; secure channel is established. The reply message contains a MAC signature and the data field is encrypted using the S-ENC key
