The technological advancements in the Internet of Things (IoT) and related technologies lead to revolutionary many sectors. One these sectors, is industrial sector red that leverages IoT forming Industrial (IIoT). IIoT has potential enhance manufacturing process by improving quality, trace-ability, integrity processes. enhancement achieved deploying devices (sensors) across facilities; therefor...

We study encrypted storage schemes where a client outsources data to an untrusted third-party server (such as cloud provider) while maintaining the ability privately query and dynamically update data. focus on multi-maps (EMMs), structured encryption (STE) scheme that stores pairs of label value tuples. EMMs allow queries labels return associated tuple. As responses are variable-length, subject...

With the rapid development of industrial Internet Things (IIoT) and cloud computing, an increasing number companies outsource their data to servers save costs. To protect privacy, sensitive must be encrypted before being outsourced servers. A multiuser searchable encryption (MUSE) scheme was introduced ensure high efficiency retrieval. In IIoT system with numerous users, existing MUSE schemes s...

Cloud computing has emerged as a new technology that aims to provide unlimited virtualized resources to clients and enterprises. As services and huge sensitive data are being moved to the cloud server, a new challenge arises as to how to use the migrated data in a way that preserves privacy. Due to privacy concerns, important data should be encrypted before uploading onto cloud servers, so that...
