One-time pad Encryption key Distribution

Some of these problems with digital information protection systems may be overcome by providing a mechanism which allows a content provider to encrypt digital information without requiring either a hardware or platform manufacturer or a content consumer to provide support for the specific form of corresponding decryption. This mechanism can be provided in a manner which allows the digital information to be copied easily for back-up purposes and to be transferred easily for distribution, but which should not permit copying of the digital information in decrypted form. In particular, the encrypted digital information is stored as an executable computer program which includes a decryption program that decrypts the encrypted information to provide the desired digital information, upon successful completion of an authorization procedure by the user. In combination with other mechanisms that track distribution, enforce royalty payments and control access to decryption keys, the present invention provides an improved method for identifying and detecting sources of unauthorized copies. Suitable authorization procedures also enable the digital information to be distributed for a limited number of uses and/or users, thus enabling per-use fees to be charged for the digital information.

Method, device and system for V2G battery management

InactiveCN104319799AAddressing lack of functionalityAchieve the effect of intelligent charging and dischargingSecondary cellsAc network load balancingPWM rectifierPower grid
The invention discloses a method, device and system for V2G battery management. The system comprises a controllable PWM rectifier used for receiving the alternating current from a power grid and also used for converting of the alternating current and the direct current, a both-way DC / DC converter used for changing the direction of the current, a detector used for detecting a battery pack to obtain detection data and sending the detection data to a controller, the controller used for receiving a control command from the power grid and the detection data from the detector, controlling the controllable PWM rectifier and the both-way DC / DC converter according to the control command, processing the detection data according to the preset simulation algorithm to obtain the current state of the battery pack, determining the equalization strategy of an equalization circuit according to the current state and sending the equalization strategy to the equalization circuit, and the equalization circuit used for executing the equalization strategy. By means of the method, device and system, the problem that the function of a battery management system is not complete when the battery management system is applied to the V2G technology.
