Private set intersection (PSI) is an essential cryptographic protocol that has many real world
applications. As cloud computing power and popularity have been swiftly growing, it is now …

In the cloud storage framework, once clients remotely store their data on cloud storage
providers, they will lose the physical control over their outsourced data. The risk of …

Attribute-based encryption (ABE) is a promising cryptographic tool for data owner (DO) to
realize fine-grained date sharing in the cloud computing. In the encryption of most existing …

With the development of Internet of Things (IoT) and 5G, edge computing, as a new
computing paradigm, has been widely popularized in academia and industry. Due to the …

Face recognition is one of the most important biometrics pattern recognitions, which has
been widely applied in a variety of enterprise, civilian and law enforcement. The privacy of …

Provable data possession (PDP) allows a user to outsource data with a guarantee that the
integrity can be efficiently verified. Existing publicly verifiable PDP schemes require the user …

Solving quadratic congruences is a widely applied operation in cryptographic protocols to
