We consider the problem of group key agreement among n parties communicating over an insecure ad hoc network. Firstly, we analyze the state and the problem of existing group key management schemes, and then present a secure, efficient and contributory group key management scheme, which is based on elliptic curve cryptosystems (ECC). The security of our scheme relies on the hardness of elliptic curve...
Location dependent information services (LDISs) are gaining increasing popularity in recent years. Due to limited client power and intermittent connectivity, caching is an important approach to improve the performance of LDISs. In this paper, we propose a new replacement policy called location dependent cooperative caching (LDCC). Unlike existing location dependent cache replacement policies, the...
Cache invalidation is an important issue in mobile caching and has received much attention by researchers. However most existing studies on cache invalidation strategies are limited to cellular wireless networks in which the mobile terminals can communicate with the base stations directly. In this paper, we address the seldom studied issue of cache invalidation in mobile ad hoc networks (MANETs),...
