Universally Attainable Error and Information Exponents for the Broadcast Channels with Confidential Messages
نویسندگان
چکیده
We show universally attainable exponents for the decoding error and the mutual information for the broadcast channels with confidential messages. The error exponents are the same as ones given by Körner and Sgarro for the broadcast channels with degraded message sets.

Discrete Memoryless Interference and Broadcast Channels with Confidential Messages
Discrete memoryless interference and broadcast channels in which independent confidential messages are sent to two receivers are considered. Confidential messages are transmitted to each receiver with perfect secrecy, as measured by the equivocation at the other receiver. In this paper, we derive inner and outer bounds for the achievable rate regions for these two communication systems.
متن کاملThe Three-Receiver Broadcast Channel with Degraded Message Sets and Confidential Messages
In this paper, bounds to the secrecy capacity region for the general 3-receiver broadcast channel with 3 degraded message sets, are presented for confidential messages sent to be kept secret from one of the receivers. This model is a more general model than 2-receiver broadcast channels with confidential messages with an external wiretapper, and recently studied 3-receiver degraded broadcast ch...
متن کاملError and Erasure Exponents for the Broadcast Channel with Degraded Message Sets
Error and erasure exponents for the broadcast channel with degraded message sets are analyzed. The focus of our error probability analysis is on the main receiver where, nominally, both messages are to be decoded. A two-step decoding algorithm is proposed and analyzed. This receiver first attempts to decode both messages, failing which, it attempts to decode only the message representing the co...
متن کاملStrong security and separated code constructions for the broadcast channels with confidential messages
We show that the capacity region of the broadcast channel with confidential messages does not change when the strong security criterion is adopted instead of the weak security criterion traditionally used. We also show a construction method of coding for the broadcast channel with confidential messages by using an arbitrary given coding for the broadcast channel with degraded message sets.
متن کاملSecrecy Capacity Region of a Multi-Antenna Gaussian Broadcast Channel with Confidential Messages
In wireless data networks, communication is particularly susceptible to eavesdropping due to its broadcast nature. Security and privacy systems have become critical for wireless providers and enterprise networks. This paper considers the problem of secret communication over the Gaussian broadcast channel, where a multi-antenna transmitter sends independent confidential messages to two users wit...
