Shedding Light on Blind Spot of Backward Privacy in Dynamic Searchable Symmetric Encryption

IEEE Access, 2023
Dynamic searchable symmetric encryption (DSSE) enables users to outsource their data while retaining the capability to search and update on the encrypted database. Although various DSSE schemes have been proposed to achieve higher efficiency and stronger

Forward and Backward Private Searchable Encryption for Cloud-Assisted Industrial IoT [PDF]

Sensors
In the cloud-assisted industrial Internet of Things (IIoT), since the cloud server is not always trusted, the leakage of data privacy becomes a critical problem. Dynamic symmetric searchable encryption (DSSE) allows for the secure retrieval of outsourced

Result-pattern-hiding Conjunctive Searchable Symmetric Encryption with Forward and Backward Privacy [PDF]

Proceedings on Privacy Enhancing Technologies, 2023
Dynamic searchable symmetric encryption (DSSE) enables the data owner to outsource its database (document sets) to an untrusted server and make searches and updates securely and efficiently. Conjunctive DSSE can process conjunctive queries that return the documents containing multiple keywords.

Searchable Encryption for Conjunctive Queries with Extended Forward and Backward Privacy [PDF]

Proceedings on Privacy Enhancing Technologies
Recent developments in the field of Dynamic Searchable Symmetric Encryption (DSSE) with forward and backward privacy have attracted much attention from both research and industrial communities. However, most DSSE schemes with forward and backward privacy schemes only support single keyword queries, which impedes its prevalence in practice.

Privacy Analysis of Forward and Backward Untraceable RFID Authentication Schemes [PDF]

Wireless Personal Communications, 2010
In this paper, we analyze the first known provably secure Radio Frequency Identification (RFID) authentication schemes that are designed to provide forward untraceability and backward untraceability: the L-K and S-M schemes. We show how to trace tags in the L-K scheme without needing to corrupt tags.

Fault-tolerant Verifiable Dynamic SSE with Forward and Backward Privacy [PDF]

IACR Communications in Cryptology
Dynamic Searchable Symmetric Encryption (DSSE) allows users to securely outsource their data to cloud servers while enabling efficient searches and updates. The verifiability property of a DSSE construction ensures that users do not accept incorrect search results from a malicious server while the fault-tolerance property guarantees the ...

Dynamic Bit Encoding for Privacy Protection against Correlation Attacks in RFID Backward Channel [PDF]

IEEE Transactions on Computers, 2013
Today Radio Frequency Identification (RFID) technologies are applied in many fields for a variety of applications. Though bringing great productivity gains, RFID systems may cause new security and privacy threats to individuals or organizations. Therefore, it is important to protect the security of RFID systems and the privacy of RFID tag owners ...

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
