Abstract: A lattice-based proxy signature method, apparatus and device, a lattice-based proxy signature verification method, apparatus and device, and a storage medium. Polynomials are randomly selected in rings to calculate public and private keys of nodes, and the magnitudes of proxy public and private keys are the same as the magnitudes of public and private keys of an original signer. Therefore, compared with existing proxy signature schemes, the present application has smaller lengths of public and private keys and higher storage efficiency. Proxy signature information generated in the present application shows a signature of the original signer and also shows a signature of a proxy signer. Once a proxy signature is created, the proxy signature cannot be repudiated by the proxy signer, and has strong non-repudiation and strong unforgeability. The proxy signature method has the advantage of resisting quantum computer attack.

Abstract: A method for calibrating a first clock signal output by an oscillation module to obtain a calibrated second clock signal includes obtaining a first count value by counting a third clock signal of an external device. A second count value is obtained by counting a scan signal of the oscillation module, and a first cycle ratio is obtained based on the first count value and the second count value. It is determined whether the first clock signal has a frequency deviation by comparing the first cycle ratio with a reference cycle ratio. A frequency division coefficient of the oscillation module is adjusted when the first clock signal has the frequency deviation, so that the oscillation module divides a frequency of the first clock signal according to the adjusted frequency division coefficient, thereby obtaining the calibrated second clock signal.
