| 2 | Construction and Optimization of TRNG Based Substitution Boxes for Block Encryption Algorithms显示文摘Internet of Things is an ecosystem of interconnected devices that are accessible through the internet.The recent research focuses on adding more smartness and intelligence to these edge devices.This makes them susceptible to various kinds of security threats.These edge devices rely on cryptographic techniques to encrypt the pre-processed data collected from the sensors deployed in the field.In this regard,block cipher has been one of the most reliable options through which data security is accomplished.The strength of block encryption algorithms against different attacks is dependent on its nonlinear primitive which is called Substitution Boxes.For the design of S-boxes mainly algebraic and chaos-based techniques are used but researchers also found various weaknesses in these techniques.On the other side,literature endorse the true random numbers for information security due to the reason that,true random numbers are purely non-deterministic.In this paper firstly a natural dynamical phenomenon is utilized for the generation of true random numbers based S-boxes.Secondly,a systematic literature review was conducted to know which metaheuristic optimization technique is highly adopted in the current decade for the optimization of S-boxes.Based on the outcome of Systematic Literature Review(SLR),genetic algorithm is chosen for the optimization of s-boxes.The results of our method validate that the proposed dynamic S-boxes are effective for the block ciphers.Moreover,our results showed that the proposed substitution boxes achieve better cryptographic strength as compared with state-of-the-art techniques. | Muhammad Fahad Khan Khalid Saleem Mohammed Alotaibi Mohammad Mazyad Hazzazi Eid Rehman Aaqif Afzaal Abbasi Muhammad Asif Gondal | 2022 | Computers, Materials & Continua2022，，11： | 0 |
| 3 | Healthcare seeking trends in acute respiratory infections among children of Pakistan显示文摘AIM To assess healthcare seeking trends among Pakistani children with acute respiratory infections through comparative analysis between demographic health surveys(DHS) 2006-2007 and 2012-2013. METHODS Data of the last born children 0-24 mo of age of the sampled households from both the DHS was analyzedafter seeking permission from the DHS open access website. These were children who had suffered from cough and/or breathing difficulty in the past two weeks and sought health care thereafter. The trends of health care seeking were determined separately for the individual, household and community level according to the study parameters. χ2 test was applied to compare these trends. A P-value of < 0.05 was considered significant. RESULTS Out of 2508 children in 2006-2007 there were 1590 with acute respiratory infections(ARI) according to case definition along with 2142 out of 3419 children in 2012-2013 DHS, whose data was analyzed. During 2006-2007, 69% cases sought healthcare for ARI which improved to 79% in 2012-2013. Additionally, it was revealed that when compared between 2006-2007 and 2012-2013, improvement in care seeking practices was observed among illiterate mothers(64% vs 77%) although there was minimal change in those literate. Similarly, those women working also showed an increase in healthcare seeking from 67% to 79%. Additionally, those belonging to low and middle socioeconomic class showed a marked increase as compared to those in the higher class where there was no significant change. Whereas those living in rural communities also showed an increase from 66% to 78%.CONCLUSION Increasing health budget, improving maternal education and strengthening multi-sectoral coordination are among the effective strategies to improve outcomes associated with healthcare seeking in ARI. | Hana Mahmood Samina Mohsin Khan Saleem Abbasi Yahya Sheraz | 2017 | World Journal of Clinical Infectious Diseases2017，7，3： | 0 |
