TL;DR: A novel blind filter protocol based on comparable attribute-based encryption and “transformation” technique, which can filter out the encrypted POI records under the condition that both LBSP and proxy without knowing the user’s location information are proposed.

TL;DR: This work considers a secure search service providing fine-grained and search functionality, called attribute-based multiple keyword search (ABMKS), which can be seen as an extension of searchable encryption, and proposes an ABMKS with only multiplication operations in encrypted keyword index generation.

TL;DR: This paper is the first to present a secure, efficient fine-grained access control scheme with hidden access structure, the access structure can be expressed as AND-gates on multi-valued attributes with wildcard and has obvious advantages in efficiency.

TL;DR: This paper proposes a novel digital signature scheme in the identity-based context with proxy delegation and message recovery features and, more importantly, this scheme is quantum resistant, in a particular lattice-based signature.
