摘要 Abstract 

隨著 5G 網路技術的發展，物聯網 (IoT) 已經被應用在許多的領域。雖然 IoT 帶給我們許多的便利，然而卻有一些潛在的安全缺陷，而其主因便是 IoT 裝置通常是資源受限的，例如，低的計算力及有限制的記憶體容量。此次演講將討論一些在物聯網環境委外計算及群播細緻化存取控制之安全強化方式，用以改善在 IoT 設備的效能及隱私保護。此研究的方法被實作在樹莓派上以施行進一步的實驗。

With the development of 5G networking technology, the Internet of things (IoT) has been applied on many areas. Although IoT can bring us convenience, it has some potential security flaws due to most of IoT devices being resource constraint, e.g., low computation power and limited memory.This talk will discuss some security enhancements of IoT environment for computation outsourcing and multicast communication with fine grained access control to improve both performance and privacy protection within IoT devices. The research approaches are also implemented on Raspberry Pi for carrying out advanced experiments.
