Cognitive Radio based IEEE 802.22 deploys the concept of maximum resource utilization through dynamic resource sharing. Inter base station resource sharing is dynamic process in IEEE 802.22 and is accomplished by exchange of control messages between the neighboring base stations. Insecure transmission of control channels open vulnerable holes for the Denial of Service attacks on base station. First the paper identifies the rogue base station and replay attacks during the resource sharing between the base stations that can snatch the resources from the renter base station. Then paper presents a hybrid approach of timestamp, nonce and Digital Signature to authenticate the sender and avoid the attacks.
