Abstract: |
With rapid development of Wireless communication, more and more wireless standards appear. Cognitive radio networks (CRN) is built on cognitive radio technology which could provide a good solution for heterogeneous networks merging. However, heterogeneous networks merging leads to the various wireless standards are not compatible, and also security architectures of the different standards are not complete compatible. This paper focuses on security issues of heterogeneous networks merging. The paper firstly discusses security architectures of the current wireless standards such as: GSM, WiMAX. Then, a unified security architecture is constructed for the future cognitive radio networks. The new architecture consists of two security sub-layers: security of application layer (sub-layer 1) and physical layer (sub-layer 2). Sub-layer 1 focuses on the encryption algorithms, key management, authentication, data encryption and policy strategies. Sub-layer 2 is responsible for spectrum detection, spectrum distribution, and spectrum recycling. After analysis and discussion, we can conclude that: the proposed architecture is adaptable, scalable, and suitable for cognitive radio networks.
