Enhancing Security in Multicellular Multicast Channels Reducing Interference Power with the Best Relay Selection

Journal of Computer and Communications 2022年第1期10卷 1-26页

作者： shaikh Muhammad Rizwan ali Md. Zahurul Islam Sarkar Department of Information and Communication Technology BUP Dhaka Bangladesh Department of Electrical and Electronic Engineering RUET Rajshahi Bangladesh

The capacity of wireless networks is fundamentally limited by interference. A few research has focused on the study of the simultaneous effect of interference and correlation, and less attention has been paid to the topic of canceling simultaneous effect of interference and correlation until recently. This paper considers a secure wireless multicasting scenario through multicellular networks over spatially correlated Nakagami-m fading channel in the presence of multiple eavesdroppers. Authors are interested to protect the desired signals from eavesdropping considering the impact of perfect channel estimation (PCE) with interference and correlation. The protection of eavesdropping is also made strong reducing the simultaneous impact of interference and correlation on the secrecy multicast capacity employing opportunistic relaying technique. In terms of the signal-to-interference plus noise ratio (SINR), fading parameter, correlation coefficient, the number of multicast users and eavesdroppers and the number of antennas at the multicast users and eavesdroppers, the closed-form analytical expressions are derived for the probability of non-zero secrecy multicast capacity and the secure outage probability for multicasting to understand the insight of the effects of aforementioned parameters. The results show that the simultaneous effects of correlation and interference at the multicast users degrade security in multicasting. Moreover, the security in multicasting degrades with the intensity of fading and the number of multicast users, eavesdroppers and antennas at the eavesdroppers. The effects of these parameters on the security in multicasting can be significantly reduced by using opportunistic relaying technique with PCE. Finally, the analytical results are verified via Monte-Carlo simulation to justify the validity of derived closed-form analytical expressions.

当前,云计算技术的应用极为广泛,已融入到互联网生活的方方面面。然而,由于其架构和服务的特点,云计算的安全隐患一直存在。同时,云安全危害事件也屡屡发生。因此,云环境下的安全问题受到工业界及学术界越来越多的关注。在云计算安全性的研究中,数字取证技术属于研究热点之一。通过数字取证可以对云端安全危害行为进行调查并执行责任处理,从而大大提升用户使用云平台的信心。然而,云环境中的数字取证是较困难的。首先,由于云计算本身的分布式架构特性,其数据可能存储在多个不同的数据中心上,获取较为困难。其次,数据中心间的数据传输往往需要对数据进行压缩,会产生数据丢失,或者恶意攻击会参杂到数据中去实施。再者,由于用户隐私保护会使得透明数据缺乏,这将影响取证。本文拟对云计算用户的数据和信息安全性进行识别和分析,从而辅助数字取证调查员对云环境中的用户日志信息进行收集及取证。本文提出的方法是基于主机入侵检测系统(HIBS)思想来设计的。本文目的是设计一个标准的数字取证框架来克服云环境下数字取证的挑战,实现云端安全危害行为的监控。在本文中,我们设计一个新的系统来解决云环境中的数字取证问题。首先,引入一个基于主机的入侵检测系统(HIDS)来确保云中数据免受恶意攻击。其次,基于HIDS的反馈结果,构建一个web服务器来自动生成预警邮件和SSH消息,从而进一步限制可疑活动。最终,数字取证调查员针对可疑用户收集可靠证据数据。通过本文的相关实验和测试可以看出,HIDS系统和日志收集系统可以成为云环境下数字取证的关键组成部分。

通过对日本污水处理技术的研究,了解了中国生活污水处理的可行性、去除效果以及符合污水排放法规的要求。然而,在全球范围内,污水处理实践正面临着严峻的问题,特别是营养物质和有机物的去除,安装成本高,运行维护困难,这些都是修正和改进目前污水处理发展以提高去除效率的关键问题。从生活污水中去除有机和营养物质是废水处理厂必不可少的基础之一。因此,本研究以低成本分散处理系统johkaso去除总磷、氨氮、总氮和化学需氧量的效率评价为基础,对国内及农村地区的处理进行了研究。本研究重点介绍了通过johkasou处理生活污水的特点,包括生活污水的组成、系统的去除效率、不同季节内处理系统的机理以及处理周期的长短。该处理系统由沉淀分离槽、缺氧槽和好氧槽三部分组成,去除效率不同,旨在确定各个槽的各项指标。不同季节,生活污水中总磷的浓度范围为2.40～4.69mg/L,氨氮的浓度范围是16.3～48.6mg/L,总氮的浓度范围是23.3～55.3mg/L,化学需氧量的浓度范围是250～507 mg/L。该处理系统运用微生物来去除这些污染物。而去除率分别为,总磷25%、氨氮39%、总氮23%,化学需氧量73%.本研究中夏季对总磷、氨氮和总氮三项指标的去除率最高,而秋季对化学需氧量的去除率最高。此外,每个槽对总磷的去除贡献率分别为32.6%、28.7%、27%以及11.6%,对氨氮的去除贡献率分别为43.4%、16%、8.6%和13.7%,而对总氮的去除贡献率分别为31%、37%、12.5%和18.5%,对化学需氧量的去除贡献率分别为 22.3%、16%、39.5%和 22.1%。分析表明,由于污染物负荷单位为进水量和水量,中国研究区系统的污染物去除效率与日本相比仅仅一般。因此,为了更有效的净化,它需要符合其结构标准的适当的进水量和质量,但是该系统比在农村污水系统中广泛使用的化粪池更有效。该系统是中国农村生活污水处理的一种解决方案,因为其净化性能最佳,易损性较低。另一方面,在需要更多管线并且运行成本也被认为过高的地区,单位成本投资非常高。

红树林生态系统不仅为一些两栖动物、爬行动物以及底栖无脊椎动物和昆虫提供了非常好的生存环境,同时也为很多水生生物提供了繁殖场所。据估计,各种重要水生物种的90%至少有一半生存在红树林中,红树林与整个生态系统的生物多样性密切相关。红树林被大量的有机体用作繁殖和育种的场所。红树林在风暴潮期间减少了海岸侵蚀,它们是稳定水质的最佳来源。目前,由于不同的自然条件和人类活动的影响,近十五年来红树林正面临着覆盖率急剧下降的严重威胁。本研究将带我们更好地了解Miani hor地区红树林的存在境况。在本研究中遥感和地理信息系统技术为红树林分布和土地利用变化情况提供了有效的手段,同时利用LandsatETM和最新的Google地球图像为我们提供了有关红树林植物区系的确切信息,并得到红树林及其分布情况。作者利用Landsat数据对2001年至2016年间巴基斯坦海岸附近的Miani hor地区进行了土地利用和土地覆被变化的探索研究,尤其是对红树林的分布变化进行了分析。作者运用土地利用转移矩阵方法来衡量研究区各土地利用类型的土地覆被变化。研究表明,自2001年以来,Mianihor大量的红树林已经消失,Miani hor地区的红树林覆盖面积从在2001年的5.63%减少至2016年4.11%,共损失了 1.52%。此外,该研究还将为研究区的决策管理和经济发展提供重要的警示。
