Evaluation of ticket-based access control method applied to IoT data distribution

抄録

Fog computing provides various new services with distributing Internet of Things (IoT) data. To distribute IoT data, we apply the publish/subscribe messaging model to a fog computing system. However, the user’s private data may be distributed without his or her permission. In this paper, we propose using Ticket-based Access Control to distribute IoT data. It enables detailed control over a user’s data access. Because we need to understand the performance of the ticket authentication and authorization infrastructure, we simulate it. As a result, the average processing delay time is nearly the same when the number of authentication and authorization channels is 5 and 10. In addition, the average processing delay time is reduced by approximately 61% when compared to the case with one channel.
