Title:
Designing a Hybrid Attribute-Based Encryption Scheme Supporting Dynamic Attributes

Authors: Stefan G. Weber

Abstract:

This article presents the design of a novel hybrid attribute-based encryption scheme. The scheme is attribute-based, as it allows encrypting under logical combinations of attributes, i.e. properties that users satisfy. It is hybrid, as it combines ciphertext-policy attribute-based encryption (CP-ABE) with location-based encryption (LBE) on the level of symmetric keys. It can efficiently handle dynamic attributes with continuous values, like location, even in resource-constrained settings.
