The SHA-256 algorithm is used to ensure the integrity and authenticity of data in order to achieve a good security thus is playing an important role in various applications, such as e-transactions and bitcoins. The SHA-256 computation capacity is a main research direction of Hashing Algorithm. In order to improve the computation capacity of hardware, the proposed design first uses pipeline principle and circuitry of timing prediction to find a most efficient architecture for implementation. Then it is optimized with hash function and hardware characteristics to give a high-performance hardware architecture of SHA-256 hash. Three pipelines are used to replace the critical path in the round functions which can shorten the timing path, and divide the computation chain into independent steps. Multi-computation of SHA-256 is working in parallel pipelines, indicating that the computation capacity can be 3 times of that with standard SHA-256 implementation. The proposed SHA-256 hardware architecture has been implemented and synthesized with Intel 14nm technology. Simulation and synthesis results show the proposed SHA-256 hashing throughput can be improved by 3 times with 50.7% power reduction, at an area cost of 2.9 times compared to that of the standard implementation.

In this paper, a modulation scheme referred as spatial modulation based color-intensity shift keying (SM CISK) is proposed for visible light communication (VLC) systems. The proposed scheme amalgamates conventional color shift keying (CSK), pulse amplitude modulation (PAM), and SM together to efficiently exploit the degrees of freedom in the color, the intensity, and the spatial domains. It maintains a constant average transmit power to fulfill the non-flickering requirement for the normal illumination. The bit error rate (BER) of the proposed scheme is studied based on the maximal likelihood (ML) detection. Simulation results verify that the proposed scheme outperforms the joint color-and-spatial modulation (SM CSK) and CISK modulation scheme.

Nowadays, there is a flood of data such as naked body photos and child pornography, which is making people bloodless. In addition, people also distribute drugs through unknown dark channels. In particular, most transactions are being made through the Deep Web, the dark path. “Deep Web refers to an encrypted network that is not detected on search engine like Google etc. Users must use Tor to visit sites on the dark web” [4]. In other words, the Dark Web uses Tor's encryption client. Therefore, users can visit multiple sites on the dark Web, but not know the initiator of the site. In this paper, we propose the key idea based on the current status of such crimes and a crime information visual system for Deep Web has been developed. The status of deep web is analyzed and data is visualized using Java. It is expected that the program will help more efficient management and monitoring of crime in unkown web such as deep web, torrent etc.

Voice over Internet Protocol (VoIP) applications, such as WeChat, Whatsapp, or LINE, have gained increasing popularity during the last few years. Packets analysis of VoIP is one of the critical criminal investigation strategies for law enforcement agencies (LEAs). Due to its convenience and multi-functionality, the WeChat application is accessible by a massive amount of people in Asia, especially in Taiwan and China. Therefore, this study uses Wireshark to reveal the tool marks behind the WeChat messages and voice calls. It will be an excellent help for LEAs to identify cybercriminals and bring them to justice.

Today, quite a lot of attention is paid to the integration of information technology and medicine. E-health network development makes it possible. The principles of e-health networks imply the use of small-sized mobile medical devices - sensors and actuators. As a rule, sensors, and actuators are combined into a network and operate with other network devices: gateways, cloud servers, etc. The article discusses the network scheme, including a portable near-infrared spectrometer for molecular analysis of food products and its interaction with the Internet in the process of data collection and processing.

In order to maximize the capacity of the cooperative communication system, a power allocation scheme for multi-relay AF cooperative system based on blind relays is presented in this paper. Under the premise that the source power is known, the power allocation problem is modeled to maximize the capacity of the system and transformed into the standard convex optimization. The power allocation factors of each relay is obtained by solving the Karush-Kuhn-Tucher (KKT) condition. Finally, the capacity and outage probability of the proposed scheme are provided for the proposed power allocation scheme. Compared with the typical equal power allocation, the proposed convex optimization-based power allocation scheme achieves better performance.

The purpose of this article is to contribute to the access to quality education in Mathematics and Philosophy for all children in the country, including those in remote areas of the capital, through an IPTV platform. To do this, we offer an SDN network integrated into an IPTV infrastructure in order to have an agile and automated interactive platform, but capable of video streaming. Interactivity is managed by Verto-FreeSwitch, agility, streaming and automation are the responsibility of SDN. The interactive IPTV server performs a multicast broadcast for learners. With a web browser or an IPTV client, learners can follow courses and interact in real time with teachers via the Verto-FreeSwitch module. The use of SDN allows to benefit from a better configuration of equipment to optimize data storage servers, but when coupled with IPTV they allow democratization of access to Mathematics and Philosophy courses.

In recent years, everything has been more and more systematic, and it would generate many cyber security issues. One of the most important of these is the malware. Modern malware has switched to a high-growth phase. According to the AV-TEST Institute showed that there are over 350,000 new malicious programs (malware) and potentially unwanted applications (PUA) be registered every day. This threat was presented and discussed in the present paper. In addition, we also considered data privacy by using federated learning. Feature extraction can be performed based on malware. The proposed method achieves very high accuracy (≈0.9167) on the dataset provided by VirusTotal.

The rapid growth of IoT (Internet of Things) makes life better, but it can be a burden for IoT users to manage heterogeneous IoT devices in a timely and appropriate manner. In this paper, we propose an IoT device configuration translator for IoT-cloud services that enables IoT users who do not have expertise in IoT environments to efficiently configure their IoT devices. The user's high-level configuration based on natural language is delivered to the translator in IoT-cloud platform using NETCONF (Network Configuration Protocol). The translator, which is designed with three components using automata theory and database mapping information, translates the high-level configuration into a low-level configuration applicable to the IoT devices. This allows IoT users to configure their IoT devices without considering which protocols and platforms they work on.
