An new approach to access VANETs

With the rapid development and the extensive application of Vehicle Ad Hoc Networks (VANET), the problem of ensuring the credibility of accessing VANET has gained more and more attentions. In the view of the characteristics that the rough set theory is good at handling uncertainly information, we proposed a new approach to access VANET based on rough set theory. We introduced the Mobile Trusted Module (MTM), so the trusted attributes could be gathered, and leading to easily making access decision. Simulations prove the effectiveness and practicality of the presented scheme.
