Abstract: Through vehicular platooning, a group of autonomous vehicles move together under the same control law with maintaining constant inter-vehicle distance and velocity. Owing to many advantages in the aspect of economy, environment, and safety, platoon has been developed for AHS (Automated Highway System). But there is little study of platoon in adversarial environment. Since vehicle safety is directly related to a passenger’s life, the in-depth study of adversarial platooning is of crucial importance. In this paper, we present that an attacker in platoon can cause serious accident just by slightly modifying control law and also discuss the control system designed for mitigating the damage of accident caused by the attacker.

Abstract: GALILEO together with EGNOS will provide more robust positioning capability enhancing the adoption of satellite technologies in services where signal continuity and integrity are required, such as those related to Public Regulated Service (PRS) and Safety of Life (SOL) applications. This will have an impact on various sectors and applications, including emergency and disaster management, Search and Rescue Service (SAR) tasks and location-based services (LBS) supporting responders in mission critical operations. In this scenario, in November 2013, the SPARTACUS project started to design, realize and test in simulated and real world scenarios GALILEO-ready tracking solutions that can be deployed in operative missions for enhancing Location Awareness in emergency management and crisis operations. SPARTACUS developed new EU-specific services to ensure precise positioning and timing capabilities to three application areas: 1) tracking, tracing and localization of critical transport assets in case of major failure of existing networks; 2) tracking the flow of relief support goods from the sending side to the receiving/end place; 3) supporting coordination of first responders in disaster management operations, ensuring their safety. By its Consortium, SPARTACUS innovations include hardware adaptations, algorithms for precision improvement, dead reckoning functionalities, location awareness, and ad-hoc independent communication networks.

Abstract: One of the main methods to evaluate, to investigate and to integrate the behavior of security systems within the automotive design is by using modeling and simulation. Due to the fact that the ECUs represent more than 57% from vehicle architecture and they are using protocols to communicate through the CAN networks many possibilities for breaking security of the vehicles successfully may appear. In order to understand all of these aspects and to be able to create a simulation model for immobilizer systems, it is mandatory to represent the features and functions of all components of this kind of systems. Developing a immobilizer model include the possibility of testing virtual models in different conditions and for different functioning modes.

Abstract: Security systems employ the RFID method to protect objects and data and to ensure public safety and the safety of commercial activity, e.g. through the control over technological processes. The research activity aimed at improving the level of safety of electronic and technical protection needs to be verified through the manufacture of prototype IDs with RFID inlays.The authors presents an original experimental device enabling the implementation of individual chips in RFID inlays, which were made on a flexible base to which an RFID antenna is attached. The collection of the chip from the dispenser and an unambiguous orientation of the soldered tips in relation to the antenna are provided by a four-axis vacuum manipulator cooperating with a vision system identifying the location of the chip on the manipulator and its final application area. A computer control system enables the operation in two modes, i.e. a semi-automatic mode in which it is possible to manually control the order and the way in which individual tasks are performed, and an automatic mode conducted according to the designed algorithm. The developed device is intended for research on the ways to improve the manufacturing techniques and electronic document protection by means of RFID technologies.

Abstract: Cloud technology has undergone significant and rapid growth in recent years, providing users with ever more Cloud resources. The services offered are based on users’ usage habits, so users come to rely ever more on Cloud applications. OpenID Union proposed an authorization method, allowing the authorized transfer of users’ personal data from one Cloud to another, using personal registration information. However, since providers do not protect users’ private information, attackers can easily intercept and tamper with confidential messages. In this paper, we use the characteristics of the blind signature to support user verification of the registering provider, to protect the user’s identity, and to address known vulnerabilities in the system.

Abstract: In present, manufacturing organizations in some countries will have to submitinformation to both internal and external to the organization, called circular mail to report newswithin the organization or external relations. Administrative officer is responsibility about to senda circular mail for each organization and will be responsible for receiving letters in paper form orpublication or media message. Then the administrative officer will be read and extracted the letterand send a message in the form of emails to receivers as indicated on the letter. In mailings sendsuch potential attacks from disgruntled individuals; such as a change of email messages duringtransmission or identity thieves use a fake email address to send officials to the other party. If anattack occurs, the organization will make a loss. In terms of stability credibility and security in theuse of corporate email. This paper presents a model and how to send an email or letter online ina format that is more stable and secure by the applied technology of public key cryptography andhash function to encrypt the message to provide stability and security in the mail's circulars online.

Abstract: For tag anti-collision algorithm in the current RFID system, considering the problems of tag privacy leakage and tag being tracked, a security solution based on Hash function was put forward. A theoretical analysis and a security evaluation about the proposed solution are also made. Through the analysis and evaluation, it turns out that this solution can prevent tag from privacy leaking, being tracked, cloning and counterfeit.

Abstract: Rapid development of information technology in education not only leads to great changes in the field of education, but also results in some security risks. How to ensure the safety of teaching resources has become a hot topic in current research in the teaching system with the cloud-terminal integrated digital classroom as scene. In the paper, importance of identity authentication mechanism is proposed by analyzing defects of cloud computing firstly, multiple identity authentication technologies are adopted for privacy protection of data. Features of four technologies, password authentication, smart card authentication, USB key authentication and biometric authentication, are analyzed in details. A set of multiple identity authentication system is designed and realized. The system is designed in Detailed system architecture is designed in the system for improving dynamic password technology and fingerprint recognition technology for ensuring data operation of legitimate users. Mobile terminals should be combined as example, and actual test can be conducted aiming at account recovery, remote data destruction and other demand after unexpected loss of smart terminal equipment. The result shows that the system can ensure accuracy and reliability of account and hardware equipment with excellent test effect.

Abstract: With the development of information technology, computer and network have been widely applied into the area of energy consumption, energy conservation and pollution reduction. Information technology brings convenience into energy conservation and environment protection management, but at the same time, it also brings security issues. In the area of energy consumption, a lot of sensitive data related to national economy and society are on-line collected. Once data theft, it will bring immeasurable losses. Furthermore, data transmission between the existing energy consumption monitoring equipment and platform has no unified interface or standard. So this paper designed a chip, used as core chip in gateway, for compatibility, standards and safety during transmission, which will provide hardware and technical support for the government and enterprises to carry out monitoring of energy consumption and conservation, to achieve energy conservation and emissions reduction targets.
