Security and Privacy in Solar Insecticidal Lamps Internet of Things:Requirements and Challenges

Solar insecticidal lamps(SIL) can effectively control pests and reduce the use of pesticides. Combining SIL and Internet of Things(IoT) has formed a new type of agricultural IoT,known as SIL-IoT, which can improve the effectiveness of migratory phototropic pest control. However, since the SIL is connected to the Internet, it is vulnerable to various security issues.These issues can lead to serious consequences, such as tampering with the parameters of SIL, illegally starting and stopping SIL,etc. In this paper, we describe the overall security requirements of SIL-IoT and present an extensive survey of security and privacy solutions for SIL-IoT. We investigate the background and logical architecture of SIL-IoT, discuss SIL-IoT security scenarios, and analyze potential attacks. Starting from the security requirements of SIL-IoT we divide them into six categories, namely privacy, authentication, confidentiality, access control, availability,and integrity. Next, we describe the SIL-IoT privacy and security solutions, as well as the blockchain-based solutions. Based on the current survey, we finally discuss the challenges and future research directions of SIL-IoT.

太阳能杀虫灯物联网研究现状与展望

太阳能杀虫灯在农业趋光性害虫受灯光引诱并接触金属网时释放高压脉冲电流杀灭害虫,可有效减少施用农药造成的环境污染和食品安全问题。本文介绍了利用无线传感器网络技术提升太阳能杀虫灯在农业迁飞性趋光害虫防治领域的应用效果,明确提出了一种新型农业物联网——太阳能杀虫灯物联网。首先,从杀虫灯在国内农业生产中的应用研究现状出发,总结了杀虫灯在林果、水稻和蔬菜等作物生产种植中的部署特点和杀虫工作时段分布情况;其次,分析了现有联网型太阳能杀虫灯节点的产品特点和杀虫灯物联网研究现状;然后,结合太阳能杀虫灯的能量采集方式、田间部署特点,综合分析了基于太阳能能量采集方式的传感器网络研究现状和基于启发式的传感器网络节点部署研究现状;最后,探讨了太阳能杀虫灯物联网的节点部署、能量预留管理、虫害爆发区域边界定位、虫情数据抗干扰传输等关键研究问题,并对太阳能杀虫灯物联网在农业生产中的应用进行了总结和展望。

Impact of various vaccine boosters on neutralization against omicron following prime vaccinations with inactivated or adenovirus-vectored vaccine

SARS-CoV-2 Omicron变异株已在全球范围内广泛传播.包括中国在内的许多国家广泛接种了SARS-CoV-2灭活疫苗(IAV)、重组蛋白疫苗(PRV)和腺病毒载体疫苗(Ad V),以达到群体免疫效果.该研究系统评价了完成不同疫苗全程接种后以及接种不同疫苗加强针后的341份人血清对原始毒株和Omicron变异株的交叉中和活性.研究发现,所有类型疫苗诱导的针对Omicron变异株BA.1的中和抗体水平都明显低于原始毒株.初免疫IAV和Ad V后,分别接种Ad V和PRV的异源加强针可以最大程度地提高血清对Omicron中和活性.此外,该研究使用m RNA疫苗在小鼠模型中评估了初次免疫编码Spike蛋白的m RNA疫苗后,加强免疫编码原始毒株或者不同突变株RBD蛋白的m RNA疫苗对Omicron中和效果.结果发现,与原始毒株加强针相比,只有Omicron加强针疫苗显著地提升了Omicron的中和抗体水平.该研究对各种疫苗加强针的系统性评价可为接下来对抗Omicron变异株的免疫接种提供参考.
