Self-Recusation Protocol for Blockage of Misbehaving Applications in Vehicular Networks

Security is a fundamental issue in the deployment of any kind of network, in particular those networks that affect people integrity. It is therefore important to detect the existence of any failure and to try to avoid its propagation as much as possible. In order to take maximum advantage of ad-hoc networks, protocols should be adapted to these new technologies by proposing new alternatives to centralized systems. Along this paper, a proposal is being discussed to allow blockage of applications that show malfunctioning, through a collaborative system based on weighted accusations. This method is more effective than the complete revocation of the keys since it allows the use of critical applications.
