The invention provides an electric automobile charging management method based on a mobile terminal. The method includes that information of an automobile and an owner is registered through application programs of a mobile terminal, the nearby charging facility is searched for through GPS, a charging pile is selected to make an appointment to acquire an unlocking password, the selected charging facility is navigated, the unlocking password is input to start charging, a correlated credit card is pre-authorized on the backstage, then charging is started, charging real-time data are transmitted to an intelligent terminal through the backstage, the intelligent terminal applies a program memory and shows the data, and a backstage management system deducts the charging cost from the correlated credit card after charging is finished by the user, and the authorization is omitted. The backstage management system transmits the charging end information to a mobile phone. By means of the method, the electric automobile owner can quickly search for the charging facility, make an appointment on the charging facility, manage the charging process and analyze the charging data.

A review and vision on authentication and privacy preservation schemes in smart grid network

As the next generation of power system, smart grid provides people with great convenience in efficiency and quality. It supports two-way communication and extremely improves the efficiency of utilization of energy resource. In order to dispatch accurately and support the dynamic price, a lot of smart meters are installed at users’ house to collect the real-time data or power plan. Besides, many entities in smart grid need to share some necessary data. However, all these collected data are related to user privacy. In this paper, we make a comprehensive survey of privacy-preserving in smart grid, analyze the current privacy problems and list the corresponding solutions from a holistic angle. At last, we discuss the future work and make the conclusion.

A Comprehensive Survey of Privacy-Preserving in Smart Grid

The invention discloses a smart power grid aggregation method and system for differential privacy security and fault tolerance The method comprises the steps that a smart electric meter records and reports the electricity consumption of users in real time; a control center is responsible for collecting, processing and analyzing real-time electricity consumption data; a gateway is responsible for instruction delivery, data aggregation and security transmission between the control center and the users; a credible center is responsible for managing the whole system, and main function modules include a system initialization function module, a data aggregation request function module, a data aggregation request relay function module, a user data report function module, a security data aggregation function module and an aggregated data recovery module According to the smart power grid aggregation method and system, the common fault tolerant function is supported, a difference privacy attack can be resisted, and the phenomenon that a hostile attacker exposes and obtains privacy information of the users by eavesdropping user communication links can be resisted; when some user data are not reported successfully, the electricity consumption of all the users with normal data reporting can still be aggregated; the smart power grid aggregation method and system have the high elastic expandability and can support efficient million-scale smart power grid electricity consumption data aggregation

The invention discloses a method for authenticating anonymity groups of power-driven automobiles by a charging station and relates to the technical field of information safety. The method for authenticating the anonymity groups of the power-driven automobiles by the charging station includes the following steps that firstly, the power-driven automobiles request to access to a power grid; secondly, a central polymerizer is used for issuing a grid-accessing license for each power-driven automobile; thirdly, the automobiles request to add to a charging station of a certain zone; fourthly, a local polymerizer is used for verifying validity of the grid-accessing licenses; fifthly, the local polymerizer is used for distributing affiliated groups and signing and issuing the licenses to the power-driven automobiles; sixthly, the power-driven automobiles request to access to the charging station; seventhly, the charging station verifies whether the power-driven automobiles are allowed to access or not; eighthly, the charging station distributes a charging socket which is practical and useable for each verified power-driven automobile; ninthly, the power-driven automobiles and the charging station carry out information and energy interaction. According to the method for authenticating the anonymity groups of the power-driven automobiles by the charging station, anonymity authenticating on the automobiles by the charging station can be achieved, a vicious user can be tracked and punished to a certain degree and the group authenticating efficiency can be improved at the same time.

Different from the traditional grid, smart grid builds a real-time connection network between the user and the grid company by smart terminals, which can achieve bidirectional data transmission and information control. In smart grid, the smart meters send various information to the power generators and substations. Frequent data collection meets real-time management, but it tends to raise privacy concerns from the users about privacy information leakage. Based on the blind signature and the key distribution scheme, an efficient and privacy-preserving data collection (EPPDC) scheme is proposed for smart grid to cope with the above problems. In EPPDC scheme, the users' data information is transmitted to the local aggregator by building gateway with privacy preserving. In addition, the security analysis indicates that EPPDC scheme not only can resist replay attack, but also has source authentication and data integrity, confidentiality, unforgeability, nonrepudiation, and evolution of shared keys. Furthermore, performance analysis shows that EPPDC scheme has less computation cost than existing scheme.
