Abstract

In order to improve the application of the wireless LAN environment, safety and reliability, it is the network access process of the introduction of access control to a wireless access network of the request for access control terminal. A typical network access authentication access control technology is technology. The technology built on top of the key technologies to identity authentication technology as the basis for the security of the terminal platform itself as the premise, combined with the security agreement to ensure that access control policies to meet specific terminal can safely access the network. The technology to solve the problem of network access security has played a certain role. But traditional access control scheme is based on the terminal device itself is safe for the assumption, and therefore will make those who meet the security needs of agreement but potentially damaging or threatening their existence wireless terminal access network, and damage to the environment of the entire network. With the emergence of trusted computing technology and the deepening of its research, the wireless LAN environment, the access control problems with new solutions. (1) proposed a multi-level trusted wireless access architecture model. On the existing network access technologies based on the research, we propose a credible multi-level access wireless architecture model. The model implements the two-way access authentication capabilities to overcome the limitations of one-way authentication; in the traditional authentication platform based on the introduction of the authenticity and integrity of certified platforms, improved access control security strength: Multi-level Existing trusted access method improves \(2) proposed two remote attestation scheme. Build confidence in wireless multi-level access architecture, based on the design of two kinds of remote attestation model: \secure authentication protocol and the authorization process. Analysis showed that the two schemes from different angles on the existing remote attestation solutions privacy and security has been improved, and improved efficiency of the implementation process of protocol interactions. (3) Use TPM_emulator of the proposed theoretical model for the simulation. In the Linux operating system, with open source TPM simulator and VMware virtual machines to build a prototype experimental platform, use the appropriate technology development Glade graphical interface, and the model presented in this paper gives some validation program.
