With the ever-growing production of data coming from multiple, scattered, highly dynamical sources (like those found in IoT scenarios), it is compelling to (i) provide a seamless way to outsource the management and sharing of data (as provided by cloud services); (ii) assure an high security and privacy level to such data.

Abstract

With the ever-growing production of data coming from multiple, scattered, highly dynamical sources (like those found in IoT scenarios), it is compelling to (i) provide a seamless way to outsource the management and sharing of data (as provided by cloud services); (ii) assure an high security and privacy level to such data. As such, objectives (i) and (ii) are not easily reconcilable: for example, the way data is accessed may vary according to access policies of the users and of the cloud providers that share such data. In this paper, we argue that attribute-based proxy re-encryption is a viable solution for providing the flexibility needed in dynamic scenarios like the ones envisioned by large IoT deployments. Towards, this goal we present an efficient attribute-based, proxy re-encryption scheme that can be deployed in such scenarios, along with experimental results that confirm the viability of our approach.
