摘要: The implications and challenges of security in vehicular ad-hoc networks are huge for several reasons and, basically, human safety effects due to the complex highly dynamic setting. Additionally security, being a cross-layer topic, can be managed at different layers network stack (e.g. MAC-level - with encryption authentication, network-layer as IPsec, transport-layer TLS, SSL). A rich scientific literature has addressed issue vanet however, all proposed solutions (i) focus on specific layer (ii) offer either robust but not scalable (such PKI infrastructure, hardly under mobility nodes services) or weak ones (at least if applied safety). For this reason, present paper, is faced layered approach which lets envisage solutions, properly hierarchically differentiated distinct services. Additionally, what introduces an even stronger novelty, dissertation covers both CSMA/CA slotted MAC protocols, having latter recently encountered certain favour.
