Abstract:Attribute-Based Encryption is an encryption technique which allows to provide end-to-end encryption in situations where data is shared with multiple users, based on their roles or properties of the data. This is especially useful in situations where data is stored in an online environment, like cloud storage services. We propose a construction using ABE which allows to meet certain requirements that are, in our view, required for ABE to be practically feasible in an application. We provide an implementation of this construction, as well as implementations of several ABE schemes. Multiple experiments are performed to investigate the feasibility and performance of four selected ABE schemes in this construction, by means of an example case of an health care application. Our analysis shows that the application of ABE is feasible, as long as several conditions are met. Not all of the selected schemes turn out to be feasible, and the use of devices with limited computational resources yield unfeasible results. However, when these conditions are met, the overall performance is acceptable.
