Delegated Key-Policy Attribute-Based Set Intersection over Outsourced Encrypted Data Sets for CloudIoT

چکیده
Private set intersection (PSI) is a fundamental cryptographic primitive, allowing two parties to calculate the of their data sets without exposing additional private information. In cloud-based IoT system, IoT-enabled devices would like outsource in encrypted form cloud. this scenario, how delegate computation over outsourced cloud and achieve fine-grained access control for PSI divulging any information are still open problems. With that mind, work, we combine key-policy attribute-based encryption (KP-ABE) introduce such novel concept, called delegated (KP-ABSI), solve problem. Then propose first concrete KP-ABSI scheme analyze its efficiency.

O-PSI: Delegated Private Set Intersection on Outsourced Datasets
Private set intersection (PSI) has a wide range of applications such as privacy-preserving data mining. With the advent of cloud computing it is now desirable to take advantage of the storage and computation capabilities of the cloud to outsource datasets and delegate PSI computation. In this paper we design OPSI, a protocol for delegated private set intersection on outsourced datasets based on...

In recent years, determining the common information privately and efficiently between two mutually mistrusting parties have become an important issue in social networks. Many Private set intersection (PSI) protocols have been introduced to address this issue. By applying these protocols, two parties can compute the intersection between their sets without disclosing any information about compone...
متن کاملPrivate Key based query on encrypted data
Nowadays, users of information systems have inclination to use a central server to decrease data transferring and maintenance costs. Since such a system is not so trustworthy, users' data usually upkeeps encrypted. However, encryption is not a nostrum for security problems and cannot guarantee the data security. In other words, there are some techniques that can endanger security of encrypted d...
