Technical Field
The invention relates to the technical field of secure communication, in particular to an interactive communication method based on state transmission data.
Background
The RSSP-I secure communication protocol is suitable for security-related communication in a closed transmission system, and is used for ensuring the security of data interaction under the environment of the closed transmission system and ensuring the security of data transmission among security-related products. At present, the RSSP-I secure communication protocol only supports the transmission of RSD frame data, and cannot transmit the transmission of other types of frame data, so that the use range is greatly limited.
Disclosure of Invention
The invention aims to provide an interactive communication method based on state transmission data, so as to enrich frame data types supported by an RSSP-I secure communication protocol.
In order to realize the purpose, the invention adopts the technical scheme that: an interactive communication method based on state transmission data is provided, which comprises the following steps:
adding a BTM frame transceiving interface in an RSSP-I communication protocol;
BTM session timing control is realized on the BTM frame transceiving interface, so that the RSSP-I communication protocol supports the transceiving of the BTM frame data.
And the BTM session timing control is added on the basis of RSD frame data transceiving.
Among them, the message types of the BTM frame include SBT, EBT, ABT, BTC, and BTD.
The BTM session timing control specifically includes:
starting a session starting condition, and receiving SBT frame format data sent by a client side and checking whether a CRC field is correct by a server side;
if not, the server side continues to wait for receiving the SBT frame format data;
if the time sequence correction request and the time sequence correction reply are correct, the service end initializes the communication channel, and sends ABT frame data to the client end after the time sequence correction request and the time sequence correction reply are carried out, so that initialization is completed, and a BTM frame message transmission process is started.
The BTM frame message transmission process specifically includes:
the server receives a BTC frame data request sent by the client, and receives the BTC frame data sent by the client after performing a time sequence correction request and a time sequence correction reply;
the service end sends an ABT frame data request to the client end so as to enable the client end to carry out data transmission downloading;
the server side sends a cache data retransmission request to the client side, so that the client side enters a cache data transmission stage and receives cache data sent by the server side.
Compared with the prior art, the invention has the following technical effects: in the process of data transmission of the RSSP-I communication protocol, a BTM frame data transceiving interface is added in the RSSP-I communication protocol, and a BTM frame data session control time sequence is added on the basis of RSD frame data transmission, so that the RSSP-I communication protocol supports both RSD frame data transmission and BTM frame data transceiving.

FIG. 1 is a flow chart of an interactive communication method for transmitting data based on status according to the present invention;
FIG. 2 is a control flow diagram illustrating the timing control of BTM sessions in the present invention.
Detailed Description
To further illustrate the features of the present invention, refer to the following detailed description of the invention and the accompanying drawings. The drawings are for reference and illustration purposes only and are not intended to limit the scope of the present disclosure.
As shown in fig. 1, the present embodiment discloses an interactive communication method based on status transmission data, which includes the following steps S1 to S2:
s1, adding a BTM frame transceiving interface in the RSSP-I communication protocol;
and S2, realizing BTM conversation time sequence control on the BTM frame transceiving interface so that the RSSP-I communication protocol supports the transceiving of the BTM frame data.
It should be noted that the message types of the BTM frame include SBT, EBT, ABT, BTC and BTD, and the format thereof is as shown in table 1 below:
TABLE 1
Further, in the present embodiment, the BTM session timing control is added on the basis of RSD frame data transceiving. Therefore, the RSSP-I communication protocol in this embodiment supports both RSD frame data transmission and reception and BTM frame data transmission and reception.
Further, as shown in fig. 2, the BTM session timing control specifically includes:
starting a session starting condition, receiving SBT frame format data sent by a client by a server and checking whether a CRC field is correct or not;
if not, the server side continues to wait for receiving the SBT frame format data;
if the time sequence correction request and the time sequence correction reply are correct, the service end initializes a communication channel to send an ABT frame data request to the client end, and sends the ABT frame data to the client end after the time sequence correction request and the time sequence correction reply are carried out;
the server receives a BTC frame data request sent by the client, and receives the BTC frame data sent by the client after performing a time sequence correction request and a time sequence correction reply;
the service end sends an ABT frame data request to the client end so as to enable the client end to carry out data transmission downloading;
the server side sends a cache data retransmission request to the client side, so that the client side enters a cache data transmission stage and receives cache data sent by the server side.
It should be noted that the RSSP-I communication protocol in this embodiment only provides a BTM frame data transceiving interface, and the BTM session logic control timing is implemented by an upper layer application.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
