Constructing Subspace Membership Encryption through Inner Product Encryption
Subspace membership encryption is a generalization of inner product encryptions, which was recently formalized by Boneh, Raghunathan, and Segev in Asiacrypt 2013. The construction of this new predicate encryption was motivated by the fact that traditional predicate encryptions did not yield function privacy, a security notion introduced by Boneh et al.

Searchable Public Key Encryption Supporting Semantic Multi-Keywords Search
Searchable public key encryption (SPE) that supports multi-keywords search, allows data users to retrieve encrypted files of interest efficiently, and thus it has been intensively studied during recent years. However, most existing SPE solutions focus on

Predicate-based authenticated key exchange protocol with attribute-hiding
To overcome the problem that available predicate-based authenticated key exchange(PBAKE)protocols had drawback on privacy protection,a new PBAKE protocol was presented.The new protocol was constructed via combining an inner product encryption scheme with

Better Security for Functional Encryption for Inner Product Evaluations [PDF]
Functional encryption is a new public key paradigm that solves, in a non-interactive way, most of the security challenges raised by cloud computing. A recent paper by Abdalla, Bourse, De Caro, and Pointcheval shows a functional encryption scheme for ...
