Abstract: A system and method for authentication code generation based on adversarial machine learning are provided in this disclosure. The method includes a defensive authentication code generation system, an authentication code formation module, an authentication code scheduling module, an authentication-code adversarial processing center, an attack sample generation module, a verification and error reporting system, a division module, a grouping and distribution system, a category checking module, a data recording unit, a detection module and an integration terminal. In the system and method for authentication code generation based on adversarial machine learning according to the disclosure, attack scenes are simulated for continuous training for the authentication code, error-reporting data are recorded and optimized into the defensive authentication code generation system, so as to improve defense performance of the authentication code.

Abstract: The disclosed online transaction method and system uses payment platform acting as an intermediary agent between the merchant and the shipping company to handle the payment. While the payment platform receives payment from the shipping company, the merchant receives payment from the payment platform. The method and system do not require buyers to use the payment method provided by an intermediary transaction platform to make a payment. Instead, the buyer may pay directly to the shipping company. Unlike conventional transaction method based on COD, however, the disclosed online transaction method and system centrally manage a logistics platform or multiple logistics operations run by logistics companies. The merchant does not receive the payment from the logistics company, but rather receive the payment from a centralized payment platform to ensure secure and fast payment.

Abstract: Techniques for modeling a circuit cell of a microprocessor or other integrated circuit for hierarchical powergrid analysis are disclosed herein. Distribution coefficients, used to distribute node voltages and capacitances to respective parts of the cell, are determined for each internal node of the cell. Current distribution coefficients may also be determined for each resistor in the cell. Using the distribution coefficients, internal cell capacitances are modeled as port capacitors. Resistive elements are modeled as a resistor network having no internal nodes. Transistor elements are modeled as port current sources. Such a model permits back calculation of internal node voltages and currents.

Abstract: Ports at which a cell served by a local powergrid is to be modeled are designated on a selected metal layer N-levels down from the topmost metal layer of the local powergrid. The cell is modeled at the designated ports, excluding any metal layers above the selected metal layer. Any metal layers of the local powergrid above the selected metal layer are included as part of a model of the global powergrid, rather than as part of the local powergrid, and a hierarchical powergrid analysis is performed.

Abstract: An aspect of the current invention is directed to a method for modeling behavior of a non-linear component with a first interconnect line in a system of a plurality of interconnect lines. The method contemplates modeling an interconnect lines as a plurality of segments. Each of the segments of the interconnect line are coupled together to form the interconnect line. A non-linear component is modeled as coupled to a line segment. The line segment has an electric coupling to the other line segments, possibly on different interconnect lines. A signal associated with the first interconnect line is precharacterized. The signal is indicative of the output of the non-linear component on the line segment. The signal is then input into a linearized simulation of the system of interconnect lines.
