Jakimoski, G., Subbalakshmi, K.: Towards secure spectrum decision. This process is experimental and the keywords may be updated as the learning algorithm improves. These keywords were added by machine and not by the authors. Moreover, we propose a security architecture to mitigate the threats to spectrum sensing and decision making accordingly.
We also present the proposed security solution in and provide the security evaluation of this proposed architecture. In this paper, we briefly evaluate these new security threats and provide cryptographic and non-cryptographic countermeasures to them. However, new abilities of CRs are exposed to new security threats in addition to the existing security threats experienced in wireless networks. CRs have the ability to monitor the spectrum activities and decide on the best transmission channel depending on the measurements thereby provide agility in spectrum access. Cognitive radios (CRs) are proposed as a solution to inefficient utilization of the overcrowding spectrum and opening space for the new wireless communication technologies.
