Forward Privacy Analysis of a Dynamic Searchable Encryption Scheme
2020Dynamic searchable encryption is one branch of searchable encryption. Compared with the static searchable encryption, a dynamic searchable encryption scheme can support update (add or delete) of outsourced data. However, this kind of operation may cause data leakage.

Leakage-Resilient RFID Authentication with Forward-Privacy
2010Low power devices, such as smart-card and RFID-tags, will be used around our life including in commercial and financial activities. A prime application of such devices is entity authentication in pervasive environment. The obvious concerns in this environment involves getting security against tag-forgery (even by adversary controlled readers) and, on ...

Verifiable Blockchain-Based Searchable Encryption with forward and backward privacy
2020 16th International Conference on Mobility, Sensing and Networking (MSN), 2020Symmetric Searchable Encryption (SSE) is an ideal technology to secure searches. SSE is dedicated to improving data confidentiality without sacrificing the searchability of data. Currently, most SSE schemes work using a semihonest or curious cloud server model in which the search results are not absolutely trustworthy. Therefore, a verifiable SSE (VSSE)

A Reinforced Dynamic Multi-keyword Ranked Search with Forward Privacy
2021 IEEE Conference on Dependable and Secure Computing (DSC), 2021Searchable symmetric encryption performs satisfactorily in protecting the privacy of outsourced data in cloud storage scenarios because it encrypts data and provides a secure way of searching on the ciphertext. Dynamic searchable symmetric encryption is designed to support insertion and deletion of outsourced data.

Investigating the Privacy versus Forwarding Accuracy Tradeoff in OpportunisticInterest-Casting
IEEE Transactions on Mobile Computing, 2014Many mobile social networking applications are based on a "friend proximity detection" step, according to which two mobile users try to jointly estimate whether they have friends in common. Preserving privacy while performing "friend proximity detection" is fundamental to achieve widespread acceptance of mobile social networking applications.

Privacy and Digital Health: Causes for Concern and a Way Forward
Journal of Addiction MedicineDigital health technologies hold promise for addressing substance use disorder (SUD) treatment gaps but also introduce significant privacy risks, challenging patient autonomy and therapeutic trust. This commentary highlights how SUD digital health services, despite claims of “privacy” and “HIPAA compliance,” often utilize surveillance technologies that

GraphShield: Dynamic Large Graphs for Secure Queries with Forward Privacy
IEEE Transactions on Knowledge and Data Engineering, 2020The increasing amount of graph-structured data catalyzes analytics over graph databases using semantic queries. Motivated by the ubiquity of commercial cloud platforms, data owners are willing to store their graph databases remotely. However, data privacy has emerged as a widespread concern since the cloud platforms are not fully trusted.

A Privacy-Preserving Message Forwarding Framework for Opportunistic Cloud of Things
IEEE Internet of Things Journal, 2018As an emerging communication platform, opportunistic Cloud of Things (CoT) is promising for clients to exchange messages through opportunistic contacts in cloud computing-enabled Internet of Things. Recently, numerous socially aware schemes have been put forward, leveraging users’ social attributes and contact history to predict future contacts with ...

Cooperative Data Forwarding Strategy with Privacy Preservation
2013In the MSN, users rely on the opportunistic contacts for cooperative data forwarding. Unlike conventional wireless relay networks assuming end-device to be insensate, users have specific social features, e.g., privacy concerns and selfishness, and they will choose a data forwarding strategy under the impacts of these features. For example, when privacy
