Özet
Cognitive radios (CRs) are proposed as a solution to inefficient utilization of the overcrowding spectrum and opening space for the new wireless communication technologies. 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. However, new abilities of CRs are exposed to new security threats in addition to the existing security threats experienced in wireless networks. In this paper, we briefly evaluate these new security threats and provide cryptographic and non-cryptographic countermeasures to them. We also present the proposed security solution in [1] and provide the security evaluation of this proposed architecture. Moreover, we propose a security architecture to mitigate the threats to spectrum sensing and decision making accordingly. © Springer-Verlag Berlin Heidelberg 2010.
