Study on designing a secure gateway to realize secure IoT environments

Abstract

The Internet of Things (IoT) enables a variety of interconnected services that harvests fragile information that could be sensitive and private data belong to users and serves elegance services that could not be realized at traditional environment. Though IoT enables new internet life, it causes significantly critical security problems, information leakage. There are a lot of security functions (e.g., access control, intrusion detection) protect user's properties. However, it is hard to implement the security functions to IoT environment due to a large number of host to be involved. To resolve critical security issues on IoT environment, we proposed SafeWAY that provides user-intended dynamic security mechanisms for protecting sensitive and private information. We implement a prototype of $S_{AFE} WAY$ as the SDN based IoT Gateway with NFV system and describes how it protects user's properties with easy of use. We demonstrate how $S_{AFE} WAY$ effectively and efficiently resolves security issues through four use cases and performance evaluations.
