In vehicular ad-hoc networks (VANETs), a use case for mobile ad-hoc networks (MANETs), the ultimate goal is to let vehicles communicate using wireless message exchange to provide safety, traffic efficiency, and entertainment applications. Especially traffic efficiency applications benefit from wide-area message dissemination, and aggregation of information is an important tool to reduce bandwidth requirements and enable dissemination in large areas. The core idea is to exchange high quality summaries of the current status rather than forwarding all individual messages. Securing aggregation schemes is important, because they may be used for decisions about traffic management, as well as traffic statistics used in political decisions concerning road safety and availability. The most important challenge for security is that aggregation removes redundancy and the option to directly verify signatures on atomic messages. Existing proposals are limited, because they require roads to be segmented into small fixed-size regions, beyond which aggregation cannot be performed. In this paper, we introduce SeDyA, a scheme that allows more dynamic aggregation compared to existing work, while also providing stronger security guarantees. We evaluate SeDyA against existing proposals to show the benefits in terms of information accuracy, bandwidth usage, and resilience against attacks.
