In the recent years, the devices in Internet of Things (IoT) are growing exponentially due to the emergence of many sophisticated applications. This tremendous growth leads to serious security challenges and the devices of Wireless Sensor Networks should be protected from various attacks. IoT can be configured dynamically without fixed infrastructure and the devices are communicated with one another in an Ad-hoc manner. The work presents the classification of various DDoS attacks in the IoT environment and provides a solution for replay attack. All variations of DDoS attacks are modeled using UML based activity modeling. This clearly understands the behavior of each version of attacks and their performance in the environment. The modeling also helps to construct a solution to prevent this attack from its execution. The work also proposed a trust based protocol for replay attacks which allows the attack inside the network and blocks it after identifying the attack based on its specific behavior. The network performance is improved after implementing this proposed protocol inside the network with help of simulation under realistic conditions. The performance metrics considered in the work are energy, packet loss, computational time and throughput. The paper compares the performance with the state-of-the-art schemes such as Efficient Distributed Deterministic Key and Hash-based Message Authentication Code. The experimental analysis proved that the proposed scheme outperforms the other state-of-the-works in terms of computational cost, throughput, and delay.

A specialized low-temperature measuring cell with a cryogenic capillary system for infrared spectral analysis of ethanol developed by the authors is presented. The use of the created low-temperature cell is possible for further studies of the low-temperature properties of both pure ethanol and mixtures with its contents, which is currently an urgent task, and the data obtained with its help can be used for ice research. Two methods of ethanol research at low temperature are presented in comparison. In the first method proposed by the authors, a specially developed low-temperature measuring cell based on a diffuse reflection prefix of the Fourier spectrometer FSM 2203 with a cryogenic capillary system is used. This system allows you to achieve the required low-temperature regime at normal atmospheric pressure. The results of the experiment are compared with the traditional method of gas-phase condensation of the test sample under low temperature conditions at the pressure P = 1.0·10 –5 Torr. Infrared spectra of low molecular weight amorphous and crystalline ethanol were obtained at a temperature of 150 K at normal atmospheric pressure and in vacuum. Comparison of experimental results confirmed the operability of the new installation. In the experiments, peaks were observed in the absorption bands from 2850 to 3000 cm –1 and from 2950 to 3100 cm –1 , corresponding to the valence CH vibrations of ethanol as well as in the absorption bands from 3150 to 3400 cm –1 and from 3300 to 3500 cm –1 , which corresponds to the valence vibrations of OH. The results of the study showed the prospects of the proposed method and can be useful by researchers in the field of low-temperature spectroscopy at normal pressure.
介绍了一种专门用于乙醇红外光谱分析的低温毛细管低温测量池。使用所创建的低温电池可以进一步研究纯乙醇及其混合物的低温特性，这是目前的一项紧迫任务，并且在其帮助下获得的数据可用于冰研究。对两种低温乙醇研究方法进行了比较。在作者提出的第一种方法中，使用了一种专门开发的低温测量单元，该单元基于fsm2203傅立叶光谱仪的漫反射前缀，带有低温毛细管系统。该系统允许您在正常大气压下实现所需的低温状态。实验结果与传统的低温条件下测试样品在压力P = 1.0·10 -5 Torr条件下的气相冷凝方法进行了比较。在常压150 K和真空条件下，获得了低分子量无定形乙醇和结晶乙醇的红外光谱。实验结果的对比验证了新装置的可操作性。实验中，2850 ~ 3000 cm -1和2950 ~ 3100 cm -1的吸收波段出现峰值，对应乙醇的CH价振动;3150 ~ 3400 cm -1和3300 ~ 3500 cm -1的吸收波段出现峰值，对应OH的价振动。研究结果显示了该方法的应用前景，可为常压低温光谱研究提供参考。
