Key Aggregate Cryptography Based Solution for Dynamic Ownership Management in Fog Infrastructures

Organizations across the world are using Cloud to leverage some of its key aspects, such as reduced startup costs, data transmission expenditures, pay-as-you-use model etc. Increasing usage of Cloud based services not only raises conventional issues related to data security and privacy, but also causes handling data ownership and handling it dynamically difficult. This has now become a prominent research topic. To support real-time applications, concept of Fog computing have emerged. In this paper, we propose a model utilizing Fog computing and incorporating dynamic data ownership for data aggregation and deduplication. The technique presented in the paper uses Key Aggregate Cryptography and Bilinear groups.
