Capability Based Outsourced Data Access Control with Assured File Deletion and Efficient Revocation with Trust Factor in Cloud Computing

Abstract: Cloud computing has introduced a paradigm which support data outsourcing to third parties for processing using commodity clusters. It allows the owner to outsource sensitive data and share it with the authorized user while reducing the computation and management cost. Since owners store sensitive data over the cloud, the requirements of access control and data security have also been increasing. To alleviate all the problem requirements, the need has arisen for providing a safe, secure, and sound model. The existing solutions for these problems use pure cryptographic techniques, which increases the computation cost. In this article, the security problems are solved by using a trusted third party and a quorum of key managers. A service provider is responsible for capability-based access control to ensure that only authorized users will be able to access the data. Whenever any data revocation is required, the data owner simply updates this information to the master key manager to revoke a specific number of shares. The model for the proposed work has been presented and its analysis shows how it introduces security features.

On intuitionistic fuzzy entropy of order-α

Abstract: Using the idea of Renyi's entropy, intuitionistic fuzzy entropy of order-α is proposed in the setting of intuitionistic fuzzy sets theory. This measure is a generalized version of fuzzy entropy of order-α proposed by Bhandari and Pal and intuitionistic fuzzy entropy defined by Vlachos and Sergiadis. Our study of the four essential and some other properties of the proposed measure clearly establishes the validity of the measure as intuitionistic fuzzy entropy. Finally, a numerical example is given to show that the proposed entropy measure for intuitionistic fuzzy set is reasonable by comparing it with other existing entropies.

Host–pathogen interactome analysis of Chikungunya virus envelope proteins E1 and E2

Abstract: The envelope proteins of Chikungunya virus (CHIKV) are known to play crucial roles in viral infection and spread. Although the role of envelope proteins in viral infection has been studied, the cellular interactors of these proteins are still elusive. In the present study, the ectodomains of CHIKV envelope proteins (E1 and E2) have been used for a high throughput yeast two-hybrid (Y2H) screening to identify the interacting host protein partners. Following a comparative analysis between the viral–host protein interaction data generated from Y2H and computational approach, five host proteins interacting with E1 and three host proteins interacting with E2 common to both datasets were identified. These associations were further verified independently by pull down and protein interaction ELISA. The identified interactions shed light on the possible cellular machinery that CHIKV might be employing during viral entry, trafficking, and evasion of immune system.

Enhanced dielectric and piezoelectric properties of 0–3 PZT/PVDF composites

Abstract: Flexible piezoelectric composite films of ([PZT/]x/[PVDF]1-x (x = 0, 0.1, 0.2, 0.3) with 0–3 connectivity were synthesized from 0.2 wt% Li2CO3 added PZT ceramic powders in the morphotropic phase boundary (MPB) and PVDF polymer by solution cast technique under optimized thermal processing conditions. It is seen that crystallinity and β phase are enhanced with the addition of Li in the composite films and as well as with the volume content of PZT ceramics in PVDF matrix, thereby resulting in superior dielectric and piezoelectric properties. It is also seen that reasonably high dielectric and piezoelectric properties are obtained for 30 % of the volume content of PZT ceramics as compared to 50 % of the volume content of ceramic in the polymer matrix as reported in literature and hence, the flexibility is better in these films.
