Distributed Optimization for Utility-Security Tradeoff in Wireless Networks

摘要

The most important tool for network and communications security is encryption and decryption, wireless network security based on encryption and decryption is widely used. However, encryption and decryption consume system resources, this will inevitably lead to a decline in system performance. In this work, we jointly consider the security and wireless network performance, where security measure and wireless network performance are quantified by the function of the key length and network utility respectively. This results an optimal utilitysecurity tradeoff in context of wireless networks, simulation results validate our arguments.
