Here, the WebSocket in step 201 is a long connection protocol based on TCP, and can implement full-duplex communication between the application terminal and the television platform.
As an embodiment in specific implementation, in step 201, the WebSocket handshake request sent by the application end initiates a handshake request according to a standard WebSocket specification, where a first authentication check algorithm in the first authentication identifier carried in the first response message is an algorithm configured in the display device.
As another embodiment, in step 201, the WebSocket handshake request sent by the application end is a message obtained by adding a field of an authentication check algorithm to a request message generated according to a standard WebSocket specification, where the request message carries an authentication check algorithm supported by the application end itself, and at this time, the first authentication check algorithm in the first authentication identifier carried in the first response message is the authentication check algorithm in the WebSocket handshake request.
As an example, the first authentication check algorithm may be a known encryption algorithm, such as the md5 algorithm; or common authentication verification methods, such as verification by a verification code; other self-defined authentication and verification methods are also possible.
As an embodiment, the identifier of the application in step 201 may be a user name and a password set by the user in the application; the verification code displayed on the application terminal; the authentication information and the like that have been integrated when the application end is present are only for facilitating understanding of the identifier of the application end, and are not particularly limited.
In specific implementation, the first response packet in step 201 carries a first authentication identifier for indicating authentication of the identity of the application, which may be implemented by adding a field of the first authentication identifier after a standard WebSocket specification responds to a packet of a handshake request, for example, adding an algorithmic field and a nonce field after responding to a packet of a handshake request, where the algorithmic field is used to indicate a first authentication check algorithm, and the nonce field is used to indicate a first random number.
As an embodiment, after receiving a first response message for initiating an identity authentication request, an application terminal may obtain a first authentication identifier in the first response message, and the first authentication identifier may trigger the application terminal to initiate the identity authentication request.
As an embodiment, in step 202, authenticating the first authentication parameter carried in the identity authentication request is to generate a first verification parameter based on the obtained identifier of the application terminal and the first random number according to a first authentication verification algorithm; comparing whether the first authentication parameter is matched with the first verification parameter, and if so, passing the authentication of the identity of the application end; and if not, the identity authentication of the application end is not passed.

a, step a: configuring an API related to the authentication process shown in fig. 2 in a controller of the display device, where the API is configured to receive an authentication request sent by an application terminal; meanwhile, an API related to the authentication flow shown in fig. 2 is configured in the application terminal, and the newly added API in the application terminal corresponds to the API related to the authentication flow newly configured in the controller of the display device.
In step a, an API configured in a controller of the display device is used to receive an identity authentication request initiated by the application terminal; an API configured in the application is used to send an identity authentication request.
In concrete implementation, the API related to the newly added authentication flow conforms to the JSON-RPC 2.0 specification as the API defined based on ATSC 3.0 between the previous application end and the display device, and the JSON format message is used between the interfaces to carry out data interaction in the previously established WebSocket connection.

Here, the second authentication parameter in step 301 is used to authenticate the request for data interaction.
As an embodiment, the adding of the valid time of the second random number in the second response message in step 301 is a more optimized scheme, so as to make the data interaction with the application side more secure.
As an embodiment, in the step 302, the authenticating the second authentication parameter carried in the interaction request is to generate a second verification parameter based on the obtained identifier of the application terminal and the second random number according to the first authentication verification algorithm; comparing whether the second authentication parameter is matched with the second verification parameter, if so, passing the authentication of the identity of the interactive request; if not, the authentication of the identity of the interactive request is not passed.

Step 402, the display device returns a first response message for responding to the WebSocket handshake request to the application terminal.
In this step 402, the first response message carries a first authentication identifier for indicating authentication of the identity of the application, which is implemented by adding an algorithmic field and a nonce field after the standard WebSocket specification responds to the handshake request message. The format of the first packet is as follows:
HTTP/1.1 101Switching Protocols
Upgrade:websocket
Connection:Upgrade
Sec-WebSocket-Accept:HSmrc0sMlYUkAGmm5OPpG2HaGWk＝Sec-WebSocket-Protocol:chat
algorithm:md5
nonce:88C4EF58DA7CB956BD04233FBB64E0A4
in this embodiment, the first authentication check algorithm indicated in the first response message is an md5 encryption algorithm, and the first random number is a string of random characters with a length of 32.
Step 403, the application terminal sends an identity authentication request to the display device.
In this step 403, the identity authentication request carries a first authentication parameter, the identity authentication request is sent through an API added in the application for authentication, and the format of the identity authentication request is a JSON format.
In this step 403, the first authentication parameter is generated by the first authentication identifier and the identifier of the application terminal in step 402, in this embodiment, the identifier of the application terminal may be a user name usename and a password set in the application terminal, and the first authentication parameter is calculated by using the method MD5 (username: nonce: password).
Step 404, the display device returns a second response message to the application terminal.
In this step 404, the second response message includes the result that the identity authentication of the application end passes and a second random number, where the second random number is also a string of random characters with a length of 32, but is different from the first random number, and is used to generate a second authentication parameter. In this embodiment, the second authentication parameter is used to authenticate the identity of the request for data interaction sent by the application terminal.
Step 405, the application end sends a data interaction request to the display device.
In this step 405, data interaction is performed between the application and the display device based on the API defined by ATSC 3.0. In step 405, the data interaction request sent by the application end is obtained by adding a token field to the data interaction request sent by the application end, where the token field indicates a second authentication parameter, and the following is a data interaction request sent by the application end:
{
"jsonrpc":"2.0",
"method":"org.atsc.acquire.service",
"token":"21CF3E5F78EE5CF5A9D4137E15363AC9"，
"id":37
}
and step 406, after the identity authentication of the request for data interaction sent by the application end is passed, the display device returns a processing result of the data interaction to the application end.
In this step 406, after the identity authentication of the request for data interaction sent by the application end passes, a second verification parameter is generated based on the obtained identifier of the application end and the second random number according to the first authentication verification algorithm; comparing whether the second authentication parameter is matched with the second check parameter, if so, passing the authentication of the identity of the interactive request, and returning the processing result of the interactive request after performing corresponding operation according to the interactive request; if not, the authentication of the identity of the interactive request is not passed, and the interactive request is not processed.
Through the process shown in fig. 4, after receiving a request message for establishing the WebSocket connection with an application end, the identity of the application end is verified, and if the identity authentication of the application end is not passed after verification, the identity of the application end is illegal, so that the WebSocket connection with the application end can be disconnected, and malicious connection with the illegal application end is prevented; after establishing the Websocket with a legal application end, the identity of the received data interaction request is checked to prevent the illegal request from occupying the Websocket connection established with the application end
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
