Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0030] The security authentication system based on the one-way radio and television transmission network of the present invention is mainly composed of three parts: a data source server end, a signature encryption and certificate management system, and a data receiving end (intelligent set-top box).

[0031] Data source server end: the data source server end can be a VOD server (providing video source), EPG server (provid...

Abstract

The invention discloses a security certification system based on a unidirectional transmission broadcast television network. The security certification system comprises a data source server end, a signature encryption and certificate management system and a data receiving end, and solves several security problems that the broadcast television network currently faces. On one hand, secure and reliable certification is provided for secure data transmission of a broadcast television server side, on the other hand, illegal operations that files are tampered, replaced, maliciously replaced and the like in the transmission process of the unidirectional network are effectively prevented, and meanwhile television advertisements are also prevented from being replaced by criminals with profitable advertisement of the criminals.

Description

technical field [0001] The invention relates to a network security authentication system, in particular to a security authentication system based on a radio and television unidirectional transmission network. Background technique [0002] At present, there are mainly two security authentication methods based on two-way computer networks: digital signature and digital certificate. [0003] Digital signature is the application of asymmetric key encryption technology and digital abstract technology, mainly including the signature process of the sender and the verification process of the receiver. The signature process is that the sender uses a hash function to generate a message digest from the text of the message, and then encrypts the message digest with the sender's own private key. The encrypted result is the digital signature of the message. The verification process is that the receiver first uses the same hash function as the sender to calculate the message digest from t...
