Abstract :
In this paper we consider a cognitive interference channel with two confidential messages. In our scenario, although the cognitive transmitter cooperates with the primary sender, the primary and cognitive messages must be secure at unintended receivers. The level of secrecy is measured by the equivocation rate. Also an expression is obtained for the rate-equivocation region of the discrete memoryless cognitive interference channel with confidential primary and secondary messages.
