An Attack Resilient Framework in Cognitive Radio Network Environment for Inter‑domain and Intra‑domain Communication

Abstract

Abstract In this manuscript, we have considered the number of security concerns at different aspects of network communication in hybrid (centralized or distributed) cognitive radio network cell environment by distributing it into inter-domain and intra-domain. We have identified and resolved the routing and handoff process threats in both the domains by proposing a secure communication framework. The intra-domain security threats include routing and handoff CU attacks that are firmed by a Trust Analyzer which computes the TV/TF of each transmitting node or CU. Further, the inter-domain security mechanism efficiently recognized the malicious behavior of the handoff CU during real time communication by proposing a ticket based mechanism. For this, an authentication server is liable for generating and distributing the tickets to all the handoff users by verifying their authenticity. The proposed framework is validated against conventional security mechanism over certain networking parameters such as network throughput, packet delivery ratio, packet loss ratio, falsification attack, average authentication, maximum authentication and probabilistic scenarios of authentication mechanism for both the domains.
