A monitoring system and method for radio and television data security

Abstract

The invention discloses a monitoring system and method for radio and television data security, including a network node, a network signal detector, a distributed computing unit, an extension system and a host system; After the node, a one-way telecommunication connection network signal detector is used; the network signal detector is used to collect broadcast and television network data, and transmits the broadcast and television network data to a distributed computing unit; the distributed computing unit is used for broadcasting and television network data Perform classified decryption and data interception, and perform intrusion detection on the classified and decrypted data in the extension system, and the distributed computing unit transmits the security data after the intrusion detection of the extension system to the host system. The system can realize the online reconfiguration of the hardware itself, and enhance its safety performance during operation.

Description

Technical field [0001] The present invention relates to the field of broadcasting television data, and more particularly to a monitoring system and method for radio television data security. Background technique [0002] Radio and television network technology is constantly updating, from early SDH network transmission, gradually transforming into a variety of networks such as IP network, ATM swap transmission network, HFC network, and the transmission of transmission, the broadcast TV station transmits the optical cable through the cable transmission or transform The electromagnetic signal is wirelessly transmitted, regardless of the data transmission mode, it is very susceptible to the external interference or attack, which affects the security of radio and television network. [0003] The purpose of radio and television network is to distinguish whether the transmission signal type of the broadcast television network is determined whether these transmission signal sources are ...

However, more and more asymmetric encryption, one-time pad mode, the monitor cannot identify

[0004] Using a honeypot network or a sandbox can effectively monitor attack behavior. Whether it is a honeypot network simulating an actual working network or a virtual file operating environment in a sandbox, it will take up a lot of system resources. At this stage, it is impossible to meet the needs of data security monitoring and radio and television data transmission simply by improving the computing power of the computer.
