In the embodiment of the invention two, the concrete form of RCP data message can be as shown in table 1:
| The RCP header | The RCP data |
Table 1
Wherein, the RCP header format can be as shown in table 2:
Table 2
The meaning of each field is as follows:
The version of Ver:RCP;
Type: type of message, can be divided into 2 classes, comprising:
A, request message, macrodefinition is: REQUEST;
B, response message, macrodefinition is: REPLY;
Cmd: command type, can be divided into 4 classes, comprising:
A, authentication command
B, device enumeration order
C, device parameter order
D, device data order
ErrorCode: type of error, can be divided into 2 classes, comprising:
A, command execution success, macrodefinition is: OK;
B, command execution mistake, macrodefinition is: ERROR;
Length: data length does not comprise header;
Digest: to whole data message calculation check and.
Wherein, the message of RCP data message is divided into four types:
TYPE_AUTH: message identifying.
When authenticating, first byte of data field will be as AUTH_PHASE, the current authentication phase of carrying out of mark.Subsequent byte is filled with the data in corresponding stage according to the description in mutual stage of authentication.
TYPE_DEV_LIST: device enumeration message.
When carrying out device enumeration, the list of devices that returns wraps in data field and lists each equipment successively.Between per two facility informations by character ' 0 ' separate.
TYPE_DEV_PARA: device parameter message.
When carrying out the device parameter request, the data message that returns is indicated device type in first byte of data segment, in thereafter byte according to appointed equipment Parameters data structure pad device parameter.
TYPE_DEV_DATA: device data message.
When the Returning equipment data, the data message that returns is indicated device type in first byte of data segment, fills according to appointed equipment data data structure in byte thereafter.
The RCP data field:
Data length:
RCP comes the length of specified data field by the Length field of header, simultaneously, can fill the ’ 0 ' character of no more than 8 bytes at the afterbody of each data, is 8 integral multiple to guarantee data length.
2. data check:
After the content of data segment is all ready, will be set to the Digest field of header entirely 0, then whole data message is carried out verification, algorithm and IP verification and consistent.
3. data format:
If no specified otherwise, all data formats all are binary data, directly corresponding every data structure.The syllable sequence of every data structure all adopts the network bytes order.
4. data encryption:
In authentication phase, the data field of RCP is plaintext transmission.But after authentication success, the key that all data interactions of RCP will use authentication to consult out is encrypted, to guarantee safety.
In the embodiment of the invention two, because after authentication success, the RCP data division of all RCP data messages all passes through the second shared key K a that consults out and is encrypted, therefore can prevent network intercepting, Replay Attack, password conjecture, follow the tracks of address attack etc., thereby guarantee control terminal and controlled communication between terminals safety.
