Authentication method and terminal equipment of set-top box remote control based on hash algorithm

Abstract

The invention discloses a hash algorithm-based authentication method for a remote control of a set-top box, a terminal device and a storage medium. The method includes that the remote control responds to an initial control command input by a user, and obtains a key value corresponding to the initial control command; Initially refers to the start code of the control command, the current timestamp, the key value, and the smart card number bound to the target set-top box, perform hash operation to obtain the hash value H, and send the operation result to the data gateway server, so that the data gateway The server encapsulates the operation result into a remote control command in TS packet format after the hash value verification of the operation result is passed once; after the target set-top box recognizes the remote control command according to the smart card number, it hashes the remote control command twice. The value is verified, and the operation commanded by the remote control is executed after the verification is passed. The invention can verify the protection data between the set-top box and the remote controller, and avoid the set-top box being attacked and controlled by other malicious systems.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an authentication method for a set-top box remote controller based on a hash algorithm, a terminal device and a storage medium. Background technique [0002] With the popularity of smart phones, it is a good choice for users to control the set-top box through the virtual remote control app on the smart phone. Live more users and improve economic benefits. [0003] During the research and practice of the prior art, the inventor of the present invention found that many methods or systems in the prior art for controlling set-top boxes by sending remote control commands through the virtual remote control on the smart phone are based on plain text or simple encryption It is easy to be simulated or modified by other malicious systems to send commands to control and attack the set-top box, causing the set-top box to be controlled or unusable. Therefore, it is necessary to provi...
