Design And Implementation Of Multi-Embranchment Chain Of Trust In 3GPP Networks

Trusted computing technology is an emerging technology in recent years, in recent years gained rapid development. Trusted computing technology is an important area of research is the integrity of the state of the computer systems of measurement, monitoring. In recent years, the emergence of trusted computing technology, in order to enhance the security of computer systems to ensure its credibility in running state provides good technical solution ideas.This paper studies the measurement of the integrity of Trusted Computing in the 3GPP network architecture and applications, mainly completed in the following areas:1. This paper have performed a credible analysis and research technology development and history. And this paper also took a in-depth study of the trusted platform technology as well as the physical realization of trusted platform technology entities in the structure and main functions of TPM.2. This paper examined the network connections (TNC) of the protocol functions and framework, and in this study based on the TNC-CS protocol in the integrity of the measurement of the role of architecture.2. Based on analyzing the IMA infrastructure, this paper has indicated two limitations of IMA structure:mass bandwidth occupation and privacy considerations. This paper has introduced a method to improve IMA (Integrity Measurement Architecture) based on classifying the services provided by computer into different groups, builds a multi-embranchment chain of trust and new measurement architecture. In-depth analyzing shows that this method has resolved the problem of bandwidth occupation caused by remote integrity validation authentication and privacy considerations.3. On the 3GPP-SAE networks have been studied, in-depth analysis of E-UTRAN and MME of the control surfaces of the SCTP protocol stack based on the proposed connection establishment phase in the SCTP nested TNC-CS message solutions, successfully achieved 3GPP-SAE network of TNC-CS protocol support.4. SCTP protocol in the use of nested TNC-CS on the basis of the agreement will be based on the integrity of the multi-branch chain of trust measurement architecture applied to HeNB home base station, the realization of the MME entities carrier 3GPP-SAE network HeNB the integrity of the challenges of and verified. The integrity of the adoption of the HeNB measurement programs, telecom operators can access and core network HeNB the integrity of the state to achieve good control purposes, thereby prevent them from being attacked or hidden safety problems HeNB the destruction of the operator's network.As the 3GPP-SAE network of broad prospects for development and home base station (HeNB) applications. HeNB will become even more pressing security needs, while HeNB the integrity of the measurement and application of packet-based multi-branch chain of trust the integrity measurement architecture, application prospects wider.
