Abstract (in Japanese) (See Japanese page) 
(in English) In the fifth-generation mobile communications system (5G), massive machine-type communications (mMTC), which accommodates wireless access from many Internet of things (IoT) terminals has been considered as one of the main use cases. To realize mMTC, interleave division multiple access (IDMA) scheme is studied as a kind of non-orthogonal multiple access schemes which can increase a system capacity. Meanwhile, there is a security problem that more and more cyber-attacks to IoT have been increased every year. To tackle this problem in mMTC scenario, we previously proposed a single user chaos IDMA (SUC-IDMA) scheme. However, it could ensure the physical layer security to one user and remaing users were weakly protected by a chaotic interleaver. Therefore, in this paper, we propose a chaos-based multi-user IDMA, and show that the proposed scheme ensure both the physical layer security and channel coding gain to all users by numerical simulations.
