Addressless: A new internet server model to prevent network scanning

Eliminating unnecessary exposure is a principle of server security. The huge IPv6 address space enhances security by making scanning infeasible, however, with recent advances of IPv6 scanning technologies, network scanning is again threatening server security. In this paper, we propose a new model named addressless server, which separates the server into an entrance module and a main service module, and assigns an IPv6 prefix instead of an IPv6 address to the main service module. The entrance module generates a legitimate IPv6 address under this prefix by encrypting the client address, so that the client can access the main server on a destination address that is different in each connection. In this way, the model provides isolation to the main server, prevents network scanning, and minimizes exposure. Moreover it provides a novel framework that supports flexible load balancing, high-availability, and other desirable features. The model is simple and does not require any modification to the client or the network. We implement a prototype and experiments show that our model can prevent the main server from being scanned at a slight performance cost.

Information control system of the Russian segment of the International Space Station

The development of Information Control System (ICS) of the Russian Segment of the International Space Station is considered. This Information Control System is intended for automatic and manual control of space experiments. To create high-tech conditions for scientific experiments on the ISS RS, RSC Energia performs operations for the ICS modernization on the Service Module, as well as the creation of ICS on the planned Multipurpose Laboratory Module and Science Power Module. The ICS modernization phases and principles are reviewed. The conduct of a series of high-tech scientific experiments was a practical result of the Service Module Information Control System (ICS) modernization. In 2014 two cameras were installed on the ISS. Today scientific experiment Icarus is being prepared for flight tests. The experience gained during experiments carried out allows to suggest that the ISS RS ICS will become a modern system allowing to implement the most ambitious experiments in the automatic mode on the ISS. Key words: Information Control System, ISS, space experiments, science hardware.

RESEARCH ON BIG DATA ANALYSIS OF LOCATION SERVICE AND INTELLIGENT SERVICE PLATFORM OF URBAN SCENIC SPOTS: A CASE STUDY OF GUILIN CITY, GUANGXI, CHINA

In many famous tourist cities, there is a lack of big data analysis and perception of tourist behavior, which reflected in the existence of a large number of basic data in the scenic area. Through the traditional and/or non-special sensors of the Internet of Things, a large amount of special -temporal change data is collected, including video monitors data, RFID, WIFI, temperature and humidity, water depth sensors and other big data of the Internet of Things(IoT)that can perceive the location and environmental resource information of tourists. In addition, the thermodynamic data of the distribution location of tourists' mobile phones, although these data include the behavior data of tourist groups and individuals in the scenic spot, which can be most shown by supplying, lack of in-depth analysis and intelligent service application.As we all know, Guilin, Guangxi is a famous tourist attraction in the word. In this tourism city, the big data processing methods of location service include establishing a data processing framework, information extraction, fusion and batch processing technology. As a result of the location data of tourists in the scenic spot are constantly created over time, the location service data will be processed by stream mode. At the same time, dimension reduction analysis of big data is an important link in processing as it has a large volume but a low-value density. The analysis methods of location service include kernel density analysis, GIS spatial and temporal analysis, artificial intelligence deep learning, two-dimensional mapping, visualization processing results, and extraction of hot spots or scenic spots, etc. Spatial and temporal index technology is used to manage the big data of scenic spot location service and to improve the efficiency of data query and access. At the same time, a reasonable predictive analysis of data processing results is an important research method.The main system structure of an intelligent service platform includes platform, data processing sing, and analysis end, mobile management end. The platform includes a general user service module, location service module, a communication module, etc, which is responsible for providing reasonable service to customers. The data processing and analysis end include a data receiving module and a data processing and analysis module. Responsible for receiving and processing the location service data returned by the client. The mobile management end includes the scenic spot management module. Responsible for providing the manager with the distribution of tourists in the scenic area, the location information of the staff, the location of the emergency situation and other contents, and providing great help for the manager to maintain the order of the scenic area, reasonably dispatch personnel, and launch rescue in time. Development and design to show users good models and development concepts and typical artificial intelligence products, to improve the scenic spot tourist's playing efficiency and humanized experience and reduce the management cost.

Inside - Out : Investigating Energy Efficient Façades

Placing the service systems alongside the facade is not uncommon in architecture. This “inside-out” concept can be easily seen in buildings such as the Pompidou Center in Paris or the Llyod's building in London. However, a more modern approach was taken in Düsseldorf, Germany in 2008, the Capricorn House Medienhafen Düsseldorf. This building contains a unique device in its facade- called the i-modul, which was designed by GATERMANN + SCHOSSIG. This decentralized service module, located behind the red glass panels, is equipped with technology to control the building's temperature and air-quality. It also features an integrated lighting system with sound absorption and room acoustic elements. This special feature eliminates the need for traditional technology and allows for more flexible space within the building. This paper examines the energy efficiency of the i-modul device and its relationship to preceding architectural facades, it also proposes four facades for a tower design in the New York city context. With the US being one of the greatest energy consumers on the planet, this study highlights possible design approaches that can be applied along building facades to help reduce the consumption of energy.
