DS-CKDSE: A Dual-Server Conjunctive Keyword Dynamic Searchable Encryption with Forward and Backward Security [PDF]

Entropy
Dynamic Searchable Encryption (DSE) is essential for enabling confidential search operations over encrypted data in cloud computing. However, all existing single-server DSE schemes are vulnerable to Keyword Pair Result Pattern (KPRP) leakage and fail to ...

ROSE: Robust Searchable Encryption With Forward and Backward Security

IEEE Transactions on Information Forensics and Security, 2022
Dynamic searchable symmetric encryption (DSSE) has been widely recognized as a promising technique to delegate update and search queries over an outsourced database to an untrusted server while guaranteeing the privacy of data. Many efforts on DSSE have been devoted to obtaining a good tradeoff between security and performance. However, it appears that

A Forward-Secure Signature with Backward-Secure Detection [PDF]

2008 International Conference on Information Security and Assurance (isa 2008), 2008
In this paper, we propose a method to enhance the security of Abdalla and Reyzin 's forward-secure signature scheme, by producing a backward-secure detection. In the proposed scheme, we embedded the hash-chain into the forward-secure signature scheme. It achieves not only forward-security but also backward-security for the digital signature.

Dynamic Pattern Matching on Encrypted Data With Forward and Backward Security

IET Information Security
Pattern matching is widely used in applications such as genomic data query analysis, network intrusion detection, and deep packet inspection (DPI). Performing pattern matching on plaintext data is straightforward, but the need to protect the security of ...

Forward and Backward-Secure Range-Searchable Symmetric Encryption [PDF]

Proceedings on Privacy Enhancing Technologies, 2021
Abstract Dynamic searchable symmetric encryption (DSSE) allows a client to query or update an outsourced encrypted database. Range queries are commonly needed. Previous range-searchable schemes either do not support updates natively (SIGMOD’16) or use file indexes of many long bit-vectors for distinct keywords, which only support ...
