TruMan: Trust Management for Vehicular Networks

Abstract

I would like to express my deep gratitude toward my advisor, Professor Luiz Albini, for all the guidance he offered throughout the research that led to this dissertation. His frequent ideas and suggestions were what inspired me to pursue knowledge and be encouraged to find solutions to problems that are far from simple. Furthermore, I would like to thank Professor Eduardo Todt, who has helped me in ways beyond this dissertation, and my fellow students, Eric, Nelson and Ivan, who always brought interesting conversations. I would also like to thank my friends, in particular Taiane, Cainã, Douglas, Lucas and Giancarlo for bringing joy to my life for many years. Perhaps most importantly, I would like to thank my parents, Edison and Lizmari, who supported me throughout the whole process and always reminded me that I was on a path worth pursuing, as well as my grandmother Glacial and everyone in my family. Palavras-chave: redes veiculares, gerenciamento de confiança, identificação de nós maliciosos.

VANET Security through Group Broadcast Encryption

“…While Trust Management is not in the scope of this paper, it is important to note its effect when applied to VANETs and Group Broadcast communications [12].…”

“…Nodes are responsible for their own group views, deciding which vehicles should they keep as destinations and which should be revoked. This decision process happens based on the input of a trust management system [12] defines a solution for trust management in VANETs, where every node will evaluate how much it can trust its neighbors. If a trust weight is past a threshold value for a single node, that node can be revoked from the group view.…”

“…x is the size of each sub-share of the MSK generated by nodes. As nodes must be close during the initialization phase, hop count is not considered [12].…”
