Designing a Hybrid Attribute-Based Encryption Scheme Supporting Dynamic Attributes.
Stefan Weber · 2013
Abstract. This article presents the design of a novel hybrid attributebased 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.
