Abstract (in Japanese) (See Japanese page) 
(in English) There are many cases of cyber-attacks and internal fraud targeting IoT devices. We have proposed the IoT-ZTN system that applies ZTN to IoT systems to address the security challenges of the IoT. This paper focuses to realize ZTN for services using multiple IoT devices. We propose a new component called Service Processing Component (SPC) that aggregates packets from cooperating IoT devices, and a trust score calculation method that uses weights according to the importance of each IoT device. Through experiments, we have confirmed that the more cooperating IoT devices there are, the more the latency increases.
