Problems solved by technology

[0003] However, the above-mentioned prior art has the following technical problems: the communication process between the set-top box and the target device is independent, that is, the communication parties communicate independently, so if another device breaks the random code used by the communication parties, it may It will impersonate a legitimate set-top box and communicate with the target device through the cracked random code. When communicating between devices, it is generally only based on the random code to judge whether the device communicating with it is a legitimate device. If the random code is consistent, it is considered a legitimate device and communicates. As a result, the above-mentioned counterfeit devices cannot be identified, making the current set-top box communication a security risk

Embodiment 1

[0036] figure 1 It is a schematic flow chart of an embodiment of the set-top box communication method of the present invention, the method may be executed by the set-top box, such as figure 1 As shown, the method may include:

[0037] 101. The set-top box sends a communication request for establishing a connection with the target device to the server, and the communication request includes the device identifier of the target device;

[0038] Wherein, the device identification of the target device to be established is stored in the set-top box. When the set-top box wants to communicate with the target device, it will send a communication request to the server, and carry the device identification of the target device in the request. The corresponding target device establishes a communication connection.

[0039] For example, the device identifier may be a device serial code.

[0040] Specifically, before the server sends a communication request to the set-top box, the server ...

Embodiment 2

[0053] figure 2 It is a schematic flowchart of another embodiment of the set-top box communication method of the present invention, the method may be executed by the server, such as figure 2 As shown, the method may include:

[0054] 201. The server receives a communication request sent by the top box to establish a connection with the target device, and the communication request includes the device identifier of the target device;

[0055] For example, the device identifier may be a device serial code.

[0056] 202. The server acquires target device address information corresponding to the device identifier according to the device identifier, and generates a random code;

[0057] Wherein, before receiving the communication request sent by the top box to establish a connection with the target device, the server also receives registration requests sent by the top box and the target device respectively, and the registration request includes the device identifier.

[0058] A...

Embodiment 3

[0066] image 3 It is a signaling schematic diagram of another embodiment of the set-top box communication method of the present invention. This embodiment is a more specific description of the set-top box communication method of the present invention, as shown in image 3 As shown, the method includes:

[0067] 301. The set-top box and the target device send a registration request to the server, where the registration request includes a device identifier;

[0068] Among them, the communication network where the set-top box and the target device are located can be called a media switching network; when the set-top box and the target device are connected to the media switching network, they need to first register with the server; the target device can be a set-top box, other servers, terminals, etc.

[0069] The registration request may include some parameter information of the device itself, such as device serial code and other information; the device may also carry the user ...

Abstract

The invention provides a communication method, a communication device and a communication system for a set top box. The method comprises the following steps of: sending a communication request connected to target equipment to a server, wherein the communication request comprises an equipment mark of the target equipment; receiving a random code returned from the server and target equipment address information corresponding to the equipment mark; and conducting encryption communication between the target equipment address information and the target equipment based on the random code encryption communication data. By the method, the device and the system, the communication security is greatly improved.

Description

technical field [0001] The present invention relates to communication technology, in particular to a set-top box communication method, device and system. Background technique [0002] As the processing capability of the set-top box becomes stronger and stronger, data communication between the set-top box and external devices becomes more and more frequent. When the current set-top box communicates with the target device, it can communicate in the form of a random code, that is, the two sides of the communication store a consistent random code, and communicate by encrypting and decrypting messages on the basis of the random code. Wherein, the random code is stored in the device when the communication device leaves the factory. Since the communication device is usually manufactured by the operator in the factory, the manufacturer will write the random code preset by the operator into the device during production. , so the random codes of the mass-produced devices used for mut...
