Ticket-Based Schemes for Anonymity and Authentication on Wireless Mobile Networks

In wireless mobile networks (WMN), user anonymity and authentication are needed to protect the personal information of the user and the integrity of data, respectively. In this work, a ticket-based anonymity and authentication technique using an optimized algorithm called WMN_TAA-QPSO is developed. In this model, a ticket is employed to convey the query request message from the sender to the location server via a set of dummy senders established around the base station. The QPSO algorithm is also applied to locate a central node out of the neighboring base stations of the serving base station. The encrypted query message maintains security. In this respect, the misbehaving nodes were unable to access the private information of the user. As the problem described above, simulation results also demonstrate that this technique will enhance the Authentication Success Ratio (ASR) and reduce both the Authentication Delay (AD) and Communication Overhead (CO).
