Constructing Subspace Membership Encryption through Inner Product Encryption

IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2014
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.

A Secured Proxy-Based Data Sharing Module in IoT Environments Using Blockchain

Sensors, 2019
Access and utilization of data are central to the cloud computing paradigm. With the advent of the Internet of Things (IoT), the tendency of data sharing on the cloud has seen enormous growth. With data sharing comes numerous security and privacy issues.

Searchable Public Key Encryption Supporting Semantic Multi-Keywords Search

IEEE Access, 2019
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

Tongxin xuebao, 2012
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
