Fog computing is an extended technique of cloud computing and a computing model which is closer to users as well. Although the computing capability of fogs is not stronger than that of clouds, it can reduce response time, save energy and decrease the utilized network bandwidth. Needless to say, it is the trend of current smart technology development to combine the architecture of fog computing and IoT application services. However, the data sharing in fog computing is an important issue in practice, since the shared data is beyond the physical control of data owners. Meanwhile, in attribute-based encryption approaches, the access policy of ciphertext cannot remain unchanged when the shared data is processed by fog nodes. This results in that current cloud data sharing mechanisms cannot be directly applied to the architecture of fog computing. Moreover, it also lacks secure and efficient solutions to key management among fog nodes and authorization revocation. In view of the above imperfections, this project is devoted to the research on anonymous key generation, authorization revocation and attribute-based secure data sharing with deduplication in fog computing for IoTs. Four major project purposes are to (1). Propose an anonymous key generation mechanism in fog computing for IoTs; (2). Propose an authorization revocation mechanism in fog computing for IoTs; (3). Propose an attribute-based secure data sharing mechanism in fog computing for IoTs; (4). Propose a data deduplication mechanism in fog computing for IoTs. We hope to solve the problems of secure communication and data access sharing in fog computing for IoTs. In the meantime, to promote the sound development of the IoT smart technology industry. 霧計算是雲端運算的一種衍生技術，也是一種更接近使用者的運算模式。霧的運算處理能力雖然沒有雲來得強大，但卻可減少回應時間、節省能源及減少網路頻寬使用。不可諱言地，結合霧計算架構的物聯網應用服務是當前智慧科技產業發展方向，也是雲端資訊分享的一種新型態。然而，在霧計算中的資料共享會是一個實務上的重要議題，因為共享的資料超出了資料擁有者的實體控制。同時，在使用基於屬性的加密方法中，當共享的資料經由霧節點處理後，密文的存取策略無法維持不變，使得現行的雲端資料分享機制並無法直接套用於霧計算架構中。此外，霧節點之間的金鑰管理與授權註銷也欠缺安全且有效率的解決方案。鑒於上述未臻完善之處，本計畫即致力於適用於物聯網霧計算之匿名金鑰產生、授權註銷與基於屬性存取的安全資料分享暨去重複化機制之研究。四個主要的計畫目的分別為(1).提出適用於物聯網霧計算之匿名金鑰產生機制；(2).提出適用於物聯網霧計算之授權註銷機制；(3).提出適用於物聯網霧計算之基於屬性存取的安全資料分享機制；(4).提出適用於物聯網霧計算之資料去重複化機制，期望能解決當前物聯網霧計算架構下的安全通訊與資料存取分享問題，並促進物聯網智慧科技產業的健全發展。
