Broadcast Channel with Receiver Side Information: Achieving Individual Secrecy
نویسندگان
چکیده
In this paper, we study the problem of secure communication over the broadcast channel with receiver side information, under the lens of individual secrecy constraints (i.e., information leakage from each message to an eavesdropper is made vanishing). Several coding schemes are proposed by extending known results in broadcast channels to this secrecy setting. In particular, individual secrecy provided via one-time pad signal is utilized in the coding schemes. As a preliminary result, we obtain a general achievable region together with a characterization of the capacity region for the case of a degraded eavesdropper.

On The Secrecy of the Cognitive Interference Channel with Channel State
In this paper the secrecy problem in the cognitive state-dependent interference channel is considered. In this scenario we have a primary and a cognitive transmitter-receiver pairs. The cognitive transmitter has the message of the primary sender as side information. In addition, the state of the channel is known at the cognitive encoder. Hence, the cognitive encoder uses this side information t...
متن کاملA Simplified Coding Scheme for the Broadcast Channel with Complementary Receiver Side Information under Individual Secrecy Constraints
This paper simplifies an existing coding scheme for the two-receiver discrete memoryless broadcast channel with complementary receiver side information where there is a passive eavesdropper and individual secrecy is required. The existing coding scheme is simplified in two steps by replacing Wyner’s secrecy coding with Carleial-Hellman’s secrecy coding as well as removing additional randomness ...
متن کاملThe Secrecy Capacity of the 2× 2 MIMO Wiretap Channel
We consider the MIMO wiretap channel, that is a MIMO broadcast channel where the transmitter sends some confidential information to one user which is a legitimate receiver, while the other user is an eavesdropper. Perfect secrecy is achieved when the the transmitter and the legitimate receiver can communicate at some positive rate, while insuring that the eavesdropper gets zero bits of informat...
متن کاملThe Secrecy Capacity for a 3-Receiver Broadcast Channel with Degraded Message Sets
In this paper, we study the secrecy capacity region for the 3-receiver broadcast channel (BC) with degraded message sets, where a confidential message is kept secret from one of the receivers. This model is more general than the previously studied degraded broadcast channel (BC) with confidential messages, as the wiretap receiver is supposed to receive the common message. Our main results are t...
متن کاملThe Secrecy Rate Region of the Broadcast Channel
In this paper, we consider a scenario where a source node wishes to broadcast two confidential messages for two respective receivers, while a wire-tapper also receives the transmitted signal. This model is motivated by wireless communications, where individual secure messages are broadcast over open media and can be received by any illegitimate receiver. The secrecy level is measured by equivoc...
