“…Similarly, to balance the nodes' energy consumption and avoid the situation where there are some higher energy level nodes still in a dead network, the selection of a lower energy level node should have a higher cost than selecting a higher energy level node. Thus, we define the cost matrices for the simulation as follows: C1 = [5.5, 7.5, 11, 25, 31, 37, 43, 52, 63], C2 = [6,8,11,23,30,35,42,50,62], C3 = [6.5, 8.5, 12, 21, 28, 33, 40, 48, 60], C4 = [8,10,13,18,25,30,37,45,55], C5 = [8.5, 11, 15, 19, 27, 32, 38, 47, 58], C6 = [9,10,15,20,28,32,38,48,59], C7 = [9,12,16,15,20,28,33,40,50], C8 = [10,13,18,16,21,28,34,42,51], and C9 = [11,…”

Most of the previous work on threshold-cryptography-based distributed CA concentrates on the initial systems configurations and concrete protocols design, ignoring the efficiency and effectiveness of the key management service during its operation, and always assuming that there are honest nodes to carry out the service faithfully. This paper focuses on developing a selection mechanism in MANETs with selfish nodes, to dynamically select a coalition of nodes carrying out the threshold key management service optimally during system operation. First, we formulate the dynamic nodes selection problem as a combinatorial optimization problem, with the objectives of maximizing the success ratio of key management service and minimizing the nodes' cost of security and energy. Then, to ensure truth telling is the dominant strategy for any node in our scenario, we extend the payment structure of the classical Vickrey-Clarke-Groves (VCG) mechanism design framework and divide the payment into pieces to the nodes, with the consideration of their actual execution effectiveness. Simulations show that the proposed mechanism enjoys improvements of both the success ratio of key management service and lifetime of the network, as well as reductions of both the cost of participating nodes and compromising probability of MANETs, compared with the existing work.

“…Instead of studying hierarchical certification schemes, prior work focused on decentralized CAs residing within the VANET itself (Masdari and Barbin, 2012;Sen et al, 2007). However, such schemes do not provide the high level of security provided by infrastructure based CAs (Masdari and Barbin, 2012).…”

Car-to-X communication systems are about to enter the mass market in upcoming years. Security in these networks depends on digital signatures managed by a multi-level certificate hierarchy. Thereby, certificate distribution is critical in regard to channel utilization and data reception delay via security caused packet loss. These issues are even more significant in case not only pseudonym certificates but also authorization authority certificates have to be exchanged between nodes in the VANET. Prior work has not studied distribution of the elements of a multi-level certificate chain in detail. Hence, this work provides an analysis of the currently standardized mechanisms and identifies several drawbacks of the straight forward solution proposed so far. Thereby, we find a severe denial of service attack on that solution. Moreover, the distribution problem is found to be similar to the packet forwarding problem encountered in position-based routing. Thus, we study several strategies for efficient distribution of a certificate chain in regard to channel load, which are adapted from their counterparts in position-based routing. Thereby, we find that by combining pseudonym certificate buffering with requester based responder selection the requirement for certificate chain distribution in VANETs can be removed completely. Hence, the proposed design avoids the identified denial of service weakness and reduces the worst case size of the security envelope of VANET messages by more than a third.
