Encryption And Authentication

The paper objective is to determine the basic schemes and their characteristics for ensuring the security of Internet of Things nodes using symmetric authentication cryptographic microcircuits. The main results that had been obtained by using method of structural and functional design represent potentially possible options for using symmetric authentication cryptomicrocircuits to ensure the protection of Internet of Things nodes. The analysis of the presented schemes’ functioning made it possible to form the following conclusions. The host-side private key storage authentication scheme provides a fast symmetric authentication process, but requires secure storage of the private key on the host side. The simplest authentication scheme without storing a secret key on the host side, which does not imply the use of a cryptographic chip on the host side, provides a fast symmetric authentication process, but has a relatively low cryptographic strength, since the interaction in the system is performed without a random component in cryptographic transformations, which assumes constant the nature of requests in the system, and, consequently, the possibility of cryptanalysis of messages. To increase the cryptographic strength of such a scheme, it is advisable to introduce into the interaction system a random component in cryptographic transformations and use additional hashing procedures with an intermediate key, which leads to the complication of the scheme due to double hashing, but significantly increases the level of information security of IoT nodes. Downloading software in the system is implemented using secret encryption and authentication keys, which are permanently stored in the secure non-volatile memory of cryptographic chips of IoT nodes. In this case, session keys for encrypting the firmware code or decrypting it are generated on the client and host side, respectively. This approach allows creating unique downloads of the original firmware code (application) by preventing cryptanalysts from obtaining its images and algorithms. The peculiarity of the scheme of exchange of symmetric session encryption keys of messages are: use of a secret key stored on the side of the host and the client; the determination of the session key is performed as a result of hashing a random number with a secret key, that is, the exchange of the session key is performed in an encrypted secure form.

AbstractQuantum key distribution (QKD) protocols based on high-dimensional quantum states have shown the route to increase the key rate generation while benefiting of enhanced error tolerance, thus overcoming the limitations of two-dimensional QKD protocols. Nonetheless, the reliable transmission through fiber links of high-dimensional quantum states remains an open challenge that must be addressed to boost their application. Here, we demonstrate the reliable transmission over a 2-km-long multicore fiber of path-encoded high-dimensional quantum states. Leveraging on a phase-locked loop system, a stable interferometric detection is guaranteed, allowing for low error rates and the generation of 6.3 Mbit/s of a secret key rate.

The rapid development of intelligent networked vehicles (ICVs) has brought many positive effects. Unfortunately, connecting to the outside exposes ICVs to security threats. Using secure protocols is an important approach to protect ICVs from hacker attacks and has become a hot research area for vehicle security. However, most of the previous studies were carried out on V2X networks, while those on in-vehicle networks (IVNs) did not involve Ethernet. To this end, oriented to the new IVNs based on Ethernet, we designed an efficient secure scheme, including an authentication scheme using the Scalable Service-Oriented Middleware over IP (SOME/IP) protocol and a secure communication scheme modifying the payload field of the original SOME/IP data frame. The security analysis shows that the designed authentication scheme can provide mutual identity authentication for communicating parties and ensure the confidentiality of the issued temporary session key; the designed authentication and secure communication scheme can resist the common malicious attacks conjointly. The performance experiments based on embedded devices show that the additional overhead introduced by the secure scheme is very limited. The secure scheme proposed in this article can promote the popularization of the SOME/IP protocol in IVNs and contribute to the secure communication of IVNs.

With the development in the education system, considering the latest current online exam system, a new projection of online exam system based on Raspberry pi IOT is proposed, and the key implementation techniques and methods are also described. The growing ubiquity of wireless, RFID mobile and sensor devices has provide a promising opportunity to build the powerful examination systems and applications by Internet of Things (IoT). A wide range of IoT applications have been developed in recent years. In an effort to understand the development of IoT in online examination, here we propose the current research of IoT, IOT key enabling technologies, major IoT applications in online examination and identifies research trends and challenges. Here we initially all the examine details are stored in the server. Then By applying face recognition (in Open CV based) technique, you can start the online examination. Due to sometime unwanted person also enter to wright the exam, so this is the best way to identified any culprits are found or not.

The Internet Of Things

<p class="0abstract">One of the unexpected intelligence tactics known in World War II was to conceal the data in images that were reduced to the size of a point that was used in every text and transported in front of the enemy's eyes. In the new age, and after the expansion of Internet science and the use of the Internet worldwide, we will establish a security feature of the IOT service that will work more reliably and more effectively to deal with the Internet of Things and ensure the work of the services that the customer interacts with. A secret-key stenographic scheme that embeds four gray-scale secret size (128*128) pixel images into a size (512*512) pixel cover image in this work. Wavelet transform is the method used in this project to analyze the cover into its frequency components. In this work, combinations of steganography and cryptography were made to increase the level of safety and make the device more difficult for attackers to beat. The resulting stego-image that will be transmitted did not raise any suspicion by both objective and subjective evaluation, so the primary objective of Steganography is achieved. The proposed system was designed by using (MATLAB R2018b) and running on a Pentium-4 computer. The Internet of Things works with the encryption system for data in a synchronized manner with the technological development, and in order to maintain the stability of any Internet of things service, whether it is information signal services, visual or audio data, a remote control system, or data storage in the Internet cloud, we must focus on data preservation from internet pirates and internet system hackers. The picture Figure<strong> </strong>4 below shows the method of encryption and dealing with the Internet of things system..</p>
