A new method of encryption wireless energy transmission for EV in the smart grid

Abstract

Wireless charging has played a crucial role in electric vehicle charging market presently. As electric vehicles will be important nodes access to the smart grid in the future, the security flow of energy and information between wireless charging infrastructure and the smart grid will directly affect the security of the smart grid. A novel secure wireless transfer method for energy and information transfer simultaneously has been represented in this paper by designing a reasonable dual-band coil for simultaneous transmission of energy and information, using improved chaotic modulation and a three times handshake protocol for encrypting energy and information between wireless charging infrastructure and the smart grid. Both the simulation and experiments show that the security of energy transmission can be effectively improved by this structure, in the premise of ensuring the power and efficiency of wireless energy transmission.

Anonymous and Efficient Message Authentication Scheme for Smart Grid

“…In the last decade, several cryptographic protocols including digital signature [11], encryption [12,13], data aggregation [14,15], secure data storage [16][17][18], and authentication schemes [9,19] have been proposed as solutions to secure the smart grid by academia and industry [20]. The authentication scheme is the first line of defense to protect data security and enforce privacy protection for smart grids, and it is an important requirement in the deployment of smart grids.…”

Synchronous control system based on wireless data transmission for 50,000-t heavy-haul trains

“…Specifically, for a power-distributed train, the traction and brake force 6 of each locomotive 7 should cooperate in balance to avoid large forces, thus to ensure safe operation. Wireless control 8,9 holds great promise for salient performance of synchronization among multi-locomotives. 10 In China, haul freight trains of a 20,000 t capacity have successfully been put into practice with the help of GSM-R 11 Technical Standard and Locotrol wireless synchronous control system, which increases the annual transportation capacity to three times higher.…”
