Abstract
dc:descriptionΤhis thesis deals with the optimization of the users’ authentication procedure in 4th generation mobile networks. Overall, two different problems are studied. The first problem deals with the authentication latency and the associated burden of multi-pass authentications. A novel mechanism called security binding is proposed that reduces the authentication delay of multi-pass authentications in a simple yet effective and secure manner. The focal point of the proposed mechanism is its generic application in multi-pass authentications regardless of the underlying network or protocol. The performance improvement of the proposed mechanism is evaluated through extensive simulations and mathematical modeling. The second problem copes with the false synchronization issue incurred in the users’ authentication procedure. An analytical model based on a four-dimensional markov chain is developed to investigate the impact of various network parameters on the system performance. The mathematical model facilitates the dynamic adaptation of the network parameters achieving an optimal tradeoff between security and performance.
