This paper studies mobile devices mediated electronic voting system based on the distributed Pailler's encryptions; We apply the standard cut-of-the-choose technique to avoid the computational zero-knowledge proofs and show that the proposed scheme is efficient yet somewhat provably secure in the simulation-based paradigm.
When a mobile node roams in the mobile networks, its access router and routing path keeps changing. Hence the mobile node needs to authenticate the new access router and establish a new key for secure communication. To this motivation, this paper proposes a lightweight, efficient and scalable protocol to establish and update the authentication key in the mobile IPv6 networks.
This paper studies practical auction systems for allocating resources in the wireless environments. The contribution of this paper is two-fold. In the first fold, a novel solution to mobile auction (m-auction) systems is presented based on the notion of convertibly undeniable signatures which in turn, can be viewed as a light-weight version of verifiably encrypted signatures in the bulletin board...
Mobile IPv6 is an IP layer mobility protocol which allows mobile nodes to remain reachable while moving around in the Internet. In the current IETF Mobile IPv6 specifications (D. Johnson et al., 2004), when a mobile node roams, its location movement can be tracked by simply monitoring the IP addresses in IP packets. Recently, the issue of protecting location information in mobile IPv6 has received...
When a mobile node roams, its location information can be revealed from the IP prefix information of its care-of address. This paper proposes a technique for hiding a mobile node's care-of address from its correspondent node and its home address from an eavesdropper using reverse tunneling mode. In the protocol, any two real addresses regarding route optimization will never be included in a traffic...
