Efficient keyword search over graph-structured data based on minimal covered Article

Asieh GHANBARPOUR, Khashayar NIKNAFS, Hassan NADERI

Frontiers of Information Technology & Electronic Engineering 2020, Volume 21, Issue 3, Pages 448-464 doi: 10.1631/FITEE.1800133

Abstract: Keyword search is an alternative for structured languages in querying graph-structured data.A result to a keyword query is a connected structure covering all or part of the queried keywords.However, this needs a time-consuming search process, which is not appropriate for an interactive systemrecent works by confining the shape of results to examine their coverage and compactness during the searchsearch.

MULKASE: a novel approach for key-aggregate searchable encryption formulti-owner data Regular Papers

Mukti PADHYA, Devesh C. JINWALA

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 12, Pages 1717-1748 doi: 10.1631/FITEE.1800192

Abstract: Recent attempts at key-aggregate searchable encryption (KASE) combine the advantages of searching encrypteddata with support for data owners to share an aggregate searchable key with a user delegating searchA user, in turn, is required to submit only one single aggregate trapdoor to the cloud to perform a keywordsearch across the shared set of data.Security analysis proves that MULKASE is secure against chosen message attacks and chosen keyword attacks

The Security Analysis for Enhanced Data Encryption Schemes in IEEE802.11/11b WLAN

Song Yubo,Hu Aiqun,Cai Tianyou

Strategic Study of CAE 2004, Volume 6, Issue 10, Pages 32-38

Abstract:

As an expansion of LAN, the WLAN reduce the cost of building a network infrastructure, to enjoy the mobile, high-quality, multimedia services. The 802.11 standard for wireless networks includes a Wired Equivalent Privacy (WEP) protocol, which is used to protect link-layer communications from eavesdropping and other attacks. Several serious security flaws in this protocol have been discovered and some solutions have been proposed to enhance WEP security. However, it is doubtful whether they can provide enough security as these solutions lack precisely security analysis. In this paper, concrete security analyses of various enhancing mechanisms are given. Results show that these mechanisms indeed increase security and bring significant, provable security gains in WLAN environment. The authors quantify the security as a function of the security of the primitives used, thereby enabling a user to decide how to construct an enhanced mechanism for desired demands.
