Achievable Source Admission Region for Secure Lossless Broadcast Channel
Lang Fe · Journal of Nanjing University of Posts and Telecommunications · 2014
The problem of dual-source secure transmission over broadcast channel is studied using information security theory,in which the information of each receiver is unknown to the source intended for other receivers and the secure level is measured by the equivocation rate at the eavesdropping receiver. Applying separated source-channel coding scheme and combining with double binning and rate splitting technologies,an inner bound of source admission region is obtained based on the achievable and reliable transmission guaranteed,thus it can generalize existing results as a special case. in the inner bound.
