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.
