Smart Contract-Assisted Dynamically Searchable Encryption Scheme with Forward and Backward Security [PDF]
Jisuanji gongcheng, 2022 The dynamic searchable encryption process is vulnerable to file injection attacks and information abuseattacks caused by information leakage.Furthermore, the existing dynamic searchable encryption schemes based on public key cryptosystem often involve a ...

A provably lightweight and secure DSSE scheme, with a constant storage cost for a smart device client. [PDF]
PLoS ONEOutsourcing data to remote cloud providers is becoming increasingly popular amongst organizations and individuals. A semi-trusted server uses Searchable Symmetric Encryption (SSE) to keep the search information under acceptable leakage levels whilst ...

Shared and Searchable Encrypted Data for Untrusted Servers [PDF]
, 2008 Current security mechanisms pose a risk for organisations that outsource their data management to untrusted servers. Encrypting and decrypting sensitive data at the client side is the normal approach in this situation but has high communication and ...

Multi-keyword searchable encryption scheme based on dynamic cuckoo filter [PDF]
Tongxin xuebaoExisting solutions have utilized Cuckoo Filter (CF) on the server side to achieve multi-keyword searching.The capacity of CF is preset, which can not satisfy the continuous growth of the capacity expansion demand on the server side.

High Recovery with Fewer Injections: Practical Binary Volumetric Injection Attacks against Dynamic Searchable Encryption [PDF]
USENIX Security Symposium, 2023 Searchable symmetric encryption enables private queries over an encrypted database, but it also yields information leakages. Adversaries can exploit these leakages to launch injection attacks (Zhang et al., USENIX'16) to recover the underlying keywords ...

Dynamic Searchable Encryption Scheme Based on Identity [PDF]
Jisuanji gongcheng, 2019 Searchable encryption technology saves user’s local storage resources and simplifies user’s search operation.However,most searchable encryption schemes are only static search.Therefore,this paper presents a dynamic searchable encryption scheme based on ...

A Rankable Boolean Searchable Encryption Scheme Supporting Dynamic Updates in a Cloud Environment
IEEE Access, 2023 At present, three problems exist in searchable encryption in cloud storage services: firstly, most traditional searchable encryption schemes only support single-keyword search while fail to perform Boolean searches; even if a few schemes support Boolean ...
