Attribute-Based Encryption (ABE) is a powerful crypto-graphic tool that allows fine-grained access control over data. Due to its features, ABE has been adopted in several applications, such as encrypted storage or access control systems. Recently, researchers argued about the non-acceptable performance of ABE when implemented on mobile devices. In-deed, the non-feasibility of ABE on mobile devices would hinder the deployment of novel protocols and services-that could instead exploit the full potential of such devices. However, the authors believe the conclusion of non-usability was driven by a not-very efficient implementation.
