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 keywordIn MULKASE, the size of the aggregate key is independent of the number of documents held by a data ownerThe size of an aggregate key remains constant even though the number of outsourced ciphertexts goes beyond

Frontiers of Information Technology & Electronic Engineering 2018, Volume 19, Issue 4,   Pages 481-493 doi: 10.1631/FITEE.1601849

Abstract: attention has been focused on designing provably secure cryptographic primitives in the presence of keyare random, and any polynomial time adversary can obtain a certain amount of leakage on the secret keyencryption scheme is proposed, whose security is proved based on the hardness of the classic decisionalAccording to our analysis, our method can tolerate leakage attacks on the private key.from the corresponding ciphertext, and a key leakage ratio of 1/2 can be achieved.

Destructive and non-destructive evaluation of concrete for optimum sand to aggregate volume ratio

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 6,   Pages 1400-1414 doi: 10.1007/s11709-021-0779-8

Abstract: As such, a detailed experimental investigation was carried out to evaluate the effect of sand-to-aggregate, cement content (340 and 450 kg/m3), water-to-cement ratio (0.45 and 0.50), and maximum aggregateThe careful analysis demonstrates that aggregate proportions and size need to be optimized for formulatingmix designs; optimum ratios of s/a were found to be 0.40 and 0.44 for the maximum aggregate

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.
