| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Polar codes, invented by Arikan, achieve the capacity of the discrete memoryless channel with low computational and space complexity. The idea of polar codes has been extended to various coding problems. In this paper, we propose a construction of polar codes for the broadcast channel with confidential messages (BC-CM) where one transmitter sends independent confidential messages to two respective receivers. In particular, we introduce the idea of polar codes by Sasoglu and Vardy that achieve strong secrecy for the degraded wiretap channel into the chaining construction of polar codes by Wei and Ulukus that achieve weak secrecy for BC-CM. We show that proposed polar codes achieve strong secrecy and the best-known achievable rate region. | |
