This essay aims to investigate the use of an origin-ID within the Beaker Complex, as defined by John C. Barrett, seen through their different expressions of use in ceramic form and ornamentation, architecture and landscape through time and space with special emphasis on the late Neolihtics in the South of England. The analytic vehicle "the reinforcing circle" is used as a new diffusion model suggested by Stuart Needham, and the analytic tool "incubation" is used to structure the process the Beaker-cultures may have used to reach cultural hegemony. Id est, that the Beaker-cultures socially invites already existing cultures, offering within family and trading the results of new technolo­gies. And/or, occupy the space and use the authority needed by re-writing the narrative as seen in the grave use and grave deposits. The use of a Beaker origin-ID is identified as a peaceful strategy to successfully implement and fullfill a process towards cultural hegemony in areas in Europe where the Beaker cultures presence over time have been identified. / Uppsatsen är inte paginerad.

Security and privacy are among the growing concerns of a Vehicular Ad hoc Network (VANET) which requires a high degree of liability from its participants. In this dissertation, We address security, anonymity and privacy challenges of VANETs in the light of the IEEE standards for vehicular communications. VANET provides a variety of road-safety and other applications through wireless devices installed in vehicles and roadside infrastructure. A roadside infrastructure in VANET is generally public, and is prone to several different malicious attacks including node compromise, impersonation, and false message delivery attacks. Therefore, a user of a VANET must verify the integrity of a message that is delivered from a roadside infrastructure. On the other hand, a vehicle-originated message should be anonymous in order to ensure user-privacy in a VANET. However, a vehicle must not be able to take advantage of its anonymity for any misbehavior like sending false messages or malicious updates to other vehicles or a roadside infrastructure. We use proxy signature, identity-based signature, and elliptic curve cryptosystems to provide authentication for infrastructure generated messages, and anonymous authentication for vehicle originated messages. Authentication in a dense traffic condition is a challenge for a receiving entity as it incurs a processing delay at the receiving end. We address this issue with a dynamic approach that selectively verifies received messages based on a message's MAC-layer priority and a sender's information relevance. This approach makes a trade-off between priority and fairness in vehicular message authentication. We develop a network simulator to measure the impact of our authentication schemes over a WAVE protocol stack. Also, we investigate how some of the MAC-layer weaknesses may impair the security of a VANET. Our solutions are lightweight, bandwidth friendly and compatible to the current standards of vehicular communications.
