霧聯網安全機制之研究

Fog networking is a kind of network service architecture. This is designed for supporting distributed and collaborative operation in fog computing. Compared to cloud computing, which is a logically centralized architecture, fog computing supports lower latency and higher efficiency features because fog computing enables storage and computing services to reside on the right places based on the real requirements. In order to support adaptive resource allocation, SDN (Software Defined Networking) is a suitable choice for fog networking. In terms of the importance of secure communication fog computing reference architecture, this project will focus on how to build a secure fog networking. In this project, we start from the infrastructure security of the fog computing. Since SDN is widely adopted in the fog computing, we design a security mechanism for preventing the fog system loading malicious network applications. Then, we focus on the IoT scenario since it is the most popular usage of the fog computing. We make the edge server play as a proxy role to introduce modern attribute-based cryptographic technologies for devices with limited resources. Moreover, we design a security protocol to protect the device identity. This can avoid leaking user information through the device behavior.
