VPN (Virtual Private Network) device safe starting method and VPN device safe starting system

Abstract

The invention provides a VPN (Virtual Private Network) device safe starting method and a VPN device safe starting system. The VPN device is power-on, and BIOS firmware is started; a trusted cryptography module carries out HASH operation on the starting code of the BIOS firmware, and the BIOS starting code operation result is compared with a first preset legal threshold; when the BIOS starting code operation result meets the first preset legal threshold, the VPN device operation system is started; the trusted cryptography module carries out HASH operation on the starting code of the operation system, and the operation system starting code operation result is compared with a second preset legal threshold; and when the operation system starting code operation result meets the second preset legal threshold, the VPN device is started normally. The VPN device can be protected from being illegally attacked in the case of starting, the legality and the reliability of private network access can be ensured, and the information safety is ensured.

Description

technical field [0001] The invention relates to the field of cryptographic algorithms of VPN equipment, in particular to a method and system for safely starting a VPN equipment. Background technique [0002] With the rapid development of modern network technology, network interconnection has become an irresistible trend, but this interconnection method is extremely vulnerable to various attacks, resulting in illegal access to internal networks and information leakage. The full English name of VPN is Virtual Private Network, a virtual private network, which uses a public and open network (such as the Internet) as the basic transmission medium, and protects private information transmitted on the public network from being stolen and tampered with by encrypting and verifying network traffic, thereby Provide end users with network services similar to private network (Private Network) performance, but if maliciously attacked during the start-up phase, access to the private network...

[0002] With the rapid development of modern network technology, network interconnection has become an irresistible trend, but this interconnection method is extremely vulnerable to various attacks, resulting in illegal access to the internal network and information leakage

The full English name of VPN is Virtual Private Network, a virtual private network, which uses a public and open network (such as the Internet) as the basic transmission medium, and protects private information transmitted on the public network from being stolen and tampered with by encrypting and verifying network traffic, thereby Provide end users with network services similar to private network (Private Network) performance, but if maliciously attacked during the start-up phase, access to the private network will be seriously threatened. Therefore, how to secure and reliable VPN equipment is an urgent task Technical issues resolved
