A Contribution to Secure the Routing Protocol "Greedy Perimeter Stateless Routing" Using a Symmetric Signature-Based AES and MD5 Hash
This work presents a contribution to secure the routing protocol GPSR (Greedy
Perimeter Stateless Routing) for vehicular ad hoc networks, we examine the
possible attacks against GPSR and security solutions proposed by different
research teams working on ad hoc network security. Then, we propose a solution
to secure GPSR packet by adding a digital signature based on symmetric
cryptography generated using the AES algorithm and the MD5 hash function more
suited to a mobile environment
Security Analysis of Vehicular Ad Hoc Networks (VANET)
Vehicular Ad Hoc Networks (VANET) has mostly gained the attention of today's
research efforts, while current solutions to achieve secure VANET, to protect
the network from adversary and attacks still not enough, trying to reach a
satisfactory level, for the driver and manufacturer to achieve safety of life
and infotainment. The need for a robust VANET networks is strongly dependent on
their security and privacy features, which will be discussed in this paper. In
this paper a various types of security problems and challenges of VANET been
analyzed and discussed; we also discuss a set of solutions presented to solve
these challenges and problems.Comment: 6 pages; 2010 Second International Conference on Network
