  ABSTRACT: Trust relationship among multiple domains is the basis for inter-domain fast authentication. This paper proposes a fast authentication method combining inter-domain trust relationship for wireless mobile IPv6 networks. In order to implement inter-domain trust relationship, a dynamic trust maintenance mechanism is designed. Based on Combined Public Key (CPK) algorithm, a new signature and verification scheme is applied to accelerate the authentication process. This scheme supports the proposed trust-based mutual authentication between mobile node and the access network. Theoretical analysis and numerical results show that the proposed method is more effective in reducing authentication delay and signaling overhead. Additionally, the proposed method is proven to be tolerant of existential forgery and man-in-the-middle attacks.

• Conference Proceeding: Dynamic load balancing among multiple home agents for MIPv6

  ABSTRACT: In MIPv6, the home agent (HA) is the key entity to ensure a mobile nodepsilas (MN) reachability. A single HA on the home link will become a performance bottleneck. In order to enhance service availability and improve system performance, it is necessary to configure multiple HAs on the home link and efficiently balance load among these HAs. This paper proposes a dynamic multiple HA load balancing mechanism based on active overload prevention (DHALAOP). The solution actively prevents HA from overloading in advance, rather than just passively transferring excess load among HAs as previous load balancing mechanisms do. A novel dynamic weight load evaluation algorithm is introduced to provide the basis for optimal load balancing decision. In addition, DHALAOP utilizes single HA mirror image and load slicing scheme to achieve the transparency of load balancing and eliminate unnecessary additional overhead. The theoretical analysis results show that DHALAOP can be more efficient in enhancing service availability and improving system performance as compared with the previous mechanisms. At the same time it introduces a lower signaling cost.
