Abstract

The invention provides a network camera identity authentication method based on a TPCM. The method is characterized in that a network camera and a reliable gateway adopt a self-signing mode to generate a digital certificate which comprises a value of a platform configuration register and a measurement result of a memory code segment in operation. An authentication center verifies validity of the digital certificate and confirms identity of the verified party. Advantages are that a measurement value in the starting process of equipment is stored in the platform configuration register so that hardware of the network camera and the reliable gateway is ensured to be unchanged. Reliability of equipment identity is ensured from the aspect of software via measurement of the memory code segment. Besides, a signature secret key is generated by a TPCM chip and bound with the hardware platform state of the equipment so that the digital certificate is difficult to forge.

Description

technical field [0001] The invention relates to information security technology, in particular to provide an identity authentication method of a network camera by utilizing the security technology provided by trusted computing. Background technique [0002] At present, with the rapid development of information technology and network technology, the development of safe cities is constantly being promoted, and the application of network cameras in real life is becoming more and more extensive. It has also been widely used everywhere. Usually, places that need to install video surveillance systems have high security requirements. Once the surveillance system is attacked and destroyed by malicious users, the consequences will be immeasurable. Therefore, the security of the surveillance system itself needs to be guaranteed. [0003] However, in the current existing network camera monitoring system, there are still the following hidden dangers: on the one hand, the credibility of...
