Abstract
Wireless ad hoc networks are an important topic in the automotive domain. Thereby, strict security requirements lead to high effort for verification of digital signatures used to secure message exchange. A popular approach to limit such effort is to apply verify-on-demand schemes. However, we show that verify-on-demand requires much more cross layer dependencies than identified before. Moreover, a massive denial of service weakness of this kind of verification mechanism is found. Thus, we recommend to prefer verify-all schemes over their verify-on-demand counterparts.
