Abstract: A method for dynamic encryption and signing includes: obtaining, by a terminal during session connection, a predetermined first key index and a randomly-generated first signature index; signing session request data with a first signature corresponding to the first signature index; encrypting the session request data with a first key corresponding to the first key index; sending the encrypted session request data and the first signature index to the server; and receiving, from the server, session response data signed with a second signature corresponding to a second signature index and encrypted with a second key corresponding to a second key index, after decryption and signature verification by the server over the session request data succeed. The second signature index and the second key index are randomly selected by the server and saved in a login session object accessible by both the server and the terminal.

Abstract: A measurement method for an aviation-specific inductive proximity sensor (IPS for short) includes steps of: 1) building a measurement circuit, wherein an IPS comprises an internal resistance r and an inductance L; 2) building a look-up table, wherein the step 2) specifically comprises steps of: sampling a first voltage measured value U1 corresponding to a first constant delay time T1 with the ADC; sampling a second voltage measured value U2 corresponding to a second constant delay time T2 with the ADC; then obtaining voltage discharge formulas U1(T1, R, r, L) and U2(T2, R, r, L) of an r-L circuit; and 3) compressing the look-up table, utilizing the compressed look-up table for calculation during measurement. The present invention ensures that the system works within a standard temperature range, and improves measurement stability, reliability, and real-time performance. Furthermore, there is no floating point calculation, which saves CPU or MCU hardware resources.

Abstract: A method and system for implementing verification within data transfer are provided. The method includes obtaining a user card identifier and a data transfer password of a selected user card through a data transfer request interface. A data transfer verification request to a data transfer server is initiated, the data transfer verification request being generated according to the user card identifier, the data transfer password and a data transfer user identifier. A current time valid identifier that is returned by the data transfer server is received when the data transfer verification is passed, the current time valid identifier being issued when the data transfer server determines that the current time does not exceed a valid period of card-binding time of the selected user card. A secondary verification interface is skipped according to the current time valid identifier. A data transfer confirmation interface is entered.
