Pindex: Private multi-linked index for encrypted document retrieval.
PLoS ONE, 2021 Cryptographic cloud storage is used to make optimal use of the cloud storage infrastructure to outsource sensitive and mission-critical data. The continuous growth of encrypted data outsourced to cloud storage requires continuous updating.

Practical Non-Interactive Searchable Encryption with Forward and Backward Privacy [PDF]
Proceedings 2021 Network and Distributed System Security Symposium, 2021 In Dynamic Symmetric Searchable Encryption (DSSE), forward privacy ensures that previous search queries cannot be associated with future updates, while backward privacy guarantees that subsequent search queries cannot be associated with deleted documents

A Forward Privacy Model for RFID Authentication Protocols [PDF]
, 2013 In this paper, we propose a new variant of indistinguishability-based security model for the RFID authentication protocol, which allows an adversary to obtain an authentication result and secret key of a target tag. Ng et al. showed that symmetric-key based RFID authentication protocols cannot be resilient to the above information leakage ...

The impact of location privacy on opportunistic networks [PDF]
, 2011 Opportunistic networking involves forwarding messages between proximate users, who may or may not know one another. This assumes that users are willing to forward messages to each other. This assumption may not hold if users are concerned about using the

Practical privacy-aware opportunistic networking [PDF]
, 2011 Opportunistic networks have been the study of much research — in particular on making end-to-end routing efficient. Users’ privacy concerns, however, have not been the subject of much research. What privacy concerns might opportunistic network users have?

A privacy preserving authorisation system for the cloud [PDF]
, 2012 In this paper we describe a policy based authorisation infrastructure that a cloud provider can run as an infrastructure service for its users. It will protect the privacy of users’ data by allowing the users to set their own privacy policies, and then ...

Efficient dynamic searchable encryption scheme for conjunctive queries based on bidirectional index
Tongxin xuebao, 2022 To solve the problems of complicated operation, information leakage, and inflexible query method in the update process of existing dynamic searchable encryption scheme, an efficient dynamic searchable encryption scheme (named BPC-DSSE) for conjunctive ...

Forward Secure Conjunctive-Keyword Searchable Encryption
IEEE Access, 2019 Searchable symmetric encryption (SSE) has been applied in constructing secure cloud storage for its simplicity, high-efficiency, and practicality. Recent works show that forward privacy has become a fundamental property required for SSE, and several ...

DP-Forward: Fine-tuning and Inference on Language Models with Differential Privacy in Forward Pass
Proceedings of the 2023 ACM SIGSAC Conference on Computer and Communications Security, 2023 Differentially private stochastic gradient descent (DP-SGD) adds noise to gradients in back-propagation, safeguarding training data from privacy leakage, particularly membership inference. It fails to cover (inference-time) threats like embedding inversion and sensitive attribute inference. It is also costly in storage and computation when used to fine-
