Dynamic Security Architecture for Next Generation Wireless Networks

The balance between security and performance represents critical and tightly coupled challenges in the design and operation of next generation LTE networks. Security and performance are not necessarily proportional to each other. It is common that; high security measures lead to high reliability results. However over-dimensioned security measures can adversely affect the networks' performance and thus the services' quality of experience. For example a lightweight security algorithm may represent a security breach to an E-commerce application and vice versa. This paper presents a framework of dynamic security architecture that balances the trade-off between resources performance and security to optimize the performance of communication networks via tuning of security profile. The paper explores a framework to define the network security profile concept and identify its usage for security analysis and vulnerability assessment for enhancing the networks' performance. A simulation model is developed using OPNET to ground the model analytics under heavy load conditions.
