Smooth Number Message Authentication Code in the IoT Landscape

This paper presents the Smooth Number Message Authentication Code (SNMAC) for the context of lightweight IoT devices. The proposal is based on the use of smooth numbers in the field of cryptography, and investigates how one can use them to improve the security and performance of various algorithms or security constructs. The literature findings suggest that current IoT solutions are viable and promising, yet they should explore the potential usage of smooth numbers. The methodology involves several processes, including the design, implementation, and results evaluation. After introducing the algorithm, provides a detailed account of the experimental performance analysis of the SNMAC solution, showcasing its efficiency in real-world scenarios. Furthermore, the paper also explores the security aspects of the proposed SNMAC algorithm, offering valuable insights into its robustness and applicability for ensuring secure communication within IoT environments.Comment: 19 pages, 7 figure

The role of community pharmacists in depression management: a survey of attitudes, practices and perceived barriers

Background Community pharmacists play a significant role in depression care. Depression is a health priority in national health strategies around the world, including in Qatar. Objective To describe current practices, attitudes and perceived barriers of community pharmacists towards depression care, and to investigate factors associated with these practices. Setting Community pharmacies in Qatar. Method A cross-sectional online survey using an adapted survey instrument. Scores were measured on a five-point Likert scale. Descriptive univariate and bivariate analyses of study outcomes, followed by multivariate regression examining the association between pharmacists’ practices and their attitudes, socio-demographic and professional characteristics. Main outcome measure Pharmacists’ scores on self-reported attitudes towards depression and depression care practices and the number of perceived barriers for depression care. Result: 358 pharmacists (response rate 39%) completed the questionnaire. Pharmacists’ attitudes to depression were moderately positive (mean score = 3.41, SD = 0.26) but involvement in depression care was very low (mean score = 2.64, SD = 0.94). Three major barriers were lack of access to patients’ medical records (83.21%), lack of patients’ insight on depression and the importance of treatment (81.85%), and lack of knowledge and training on mental health (79.63%). Female pharmacists and those graduated more than 10 years prior were significantly less involved in depression care compared to their counterparts (practice scores (95% CI) −4.36 (−7.46 to −1.26) and -7.51 (−15.10 to −1.35), respectively), while those who had access to private counselling area were more involved (practice score 3.39 (0.20 to 6.59). Pharmacists’ depression practice score was positively associated with attitudes (p = 0.001). Conclusion Pharmacists’ moderately positive attitudes were not reflected in their suboptimal depression-care practices. Action from policymakers is needed to improve pharmacists’ practices and attitudes to depression.This study was partially funded by a Qatar University Post-Graduate Student Grant (QUST-2-CHS-2019-15)
