A quantitative study of authentication and QoS in wireless IP networks

摘要: With the increasing demand for secure and high-quality communications in public access wireless IP networks, it is very important to have an in-depth understanding of relationship between security quality service (QoS). In authentication can provide by preventing unauthorized usage negotiating credentials data transmission. Nevertheless, induces heavy overhead transmission, further deteriorating overall system performance. Thus, we analyze impact on QoS quantitatively this paper. First, introduce a model based challenge/response authentication, which widely used many mobile environments. Then, concept level proposed describe protection according nature security, i.e., information secrecy, integrity, resource availability. By taking traffic mobility patterns into account, our approach establishes direct quantitative connection through authentication. Finally, numerical results are provided demonstrate levels, performance terms delay call dropping probability.
