Problems solved by technology

[0006] Mutual authentication and key agreement between communication parties are the basis of a trusted Internet. Since the existing TPM modules are all authenticated by the PKI (Public Key Infrastructure, public key system) cryptographic system, additional digital certificates are required. Bind the public key of the platform with the identity of the platform (such as number, etc.), so that in the process of verifying the platform, the certificate needs to be verified additionally, and the transmission of the certificate also needs to occupy additional network bandwidth. Management is also very complicated, requiring network support for PKI

Abstract

The present invention discloses a bidirectional authentication method, a system, and a network device, and relates to network information security. The method may include: a network device generates an inspection parameter according to a public key of the peer network device and a private key of the network device, the public key and the private key of the network device being generated according to an identifier of the network device; and the network device performs reciprocal authentication according to the inspection parameter generated by the network device and an inspection parameter sent by the peer network device. A system and a network device for bidirectional authentication are also provided herein. As such, extra calculation caused by certificate authentication is cut down, the system is more secure and reliable, and the key management is simplified.

Description

technical field [0001] The invention relates to the field of network information security, in particular to a two-way authentication method, system and network terminal. Background technique [0002] For designers and developers of most systems and application networks, security issues are always a critical and challenging issue. Regardless of whether it is an ordinary PC system or an enterprise gateway system, various attacks and unauthorized access can easily lead to loss of key data and cause immeasurable losses. [0003] On April 8, 2003, the Trusted Computing Group (TCG, Trusted Computing Group) was established. As a standardization organization accepted by the industry, TCG has designed the basic building blocks of trusted hardware on hardware, and developed trusted software on software to resist various virtual or physical attacks. Now, products that implement these standards can be easily applied to embedded designs. [0004] Trusted Platform Module (TPM, Platform...
