Improved Leakage Abuse Attacks in Searchable Symmetric Encryption with EBPF Monitoring

Searchable Symmetric Encryption SSE allows users to search over encrypted data stored on untrusted servers, like cloud providers. While SSE hides the content of queries and documents, it still leaks patterns, such as how often a query is made. These leakages have been shown to enable leakage abus...

S-Leak: Leakage-Abuse Attack against Efficient Conjunctive SSE Via S-Term Leakage

Conjunctive Searchable Symmetric Encryption CSSE enables secure conjunctive searches over encrypted data. While leakage-abuse attacks LAAs against single-keyword SSE have been extensively studied, their extension to conjunctive queries faces a critical challenge: the combinatorial explosion of...

Enhancing Leakage Attacks on Searchable Symmetric Encryption Using LLM-Based Synthetic Data Generation

Searchable Symmetric Encryption SSE enables efficient search capabilities over encrypted data, allowing users to maintain privacy while utilizing cloud storage. However, SSE schemes are vulnerable to leakage attacks that exploit access patterns, search frequency, and volume information. Existing...

How Searchable Encryption Changes the Data Security Game

Searchable Encryption has long been a mystery. An oxymoron. An unattainable dream of cybersecurity professionals everywhere. Organizations know they must encrypt their most valuable, sensitive data to prevent data theft and breaches. They also understand that organizational data exists to be used...
