Whole property check value (or signature).
Data transmission procedure first checks whether matching security strategy when receiving the request for needing to send data.If no
Matching, then abandon this data packet.The type for checking data packet then signs to it and then carries out next step operation if broadcast packet；
If not broadcast packet, then search whether then to generate sequence of data packet there are corresponding connection (if it does not exist, then establishing connection)
Number, the code of processing movement is selected, if data need encrypted transmission, according to the Encryption Algorithm of agreement and session key logarithm
Encryption is carried out according to packet or is directly encrypted (when using symmetric encipherment algorithm) by public key.Decided whether according to the movement of selection
Message authentication is generated still to sign.Finally deliver a packet on network.
When background server receives the data packet that network interface card passes over by network, check whether with security strategy whether
Match, if mismatching, abandons this data packet；Check that the type of data packet then carries out authentication processing if broadcast packet.If certification
Failure, then abandon this data packet；If type is non-broadcasting packet, search whether to check packet sequence number there are corresponding connection
In the range of whether allowing receiving, verifying signature is determined according to type of action or verifies message, above-mentioned three kinds of situations, if
It is no, then abandon this data packet.If data packet is encrypted, exposed, then resolve packet is saved in clothes by treated
It is engaged in device database.
