Abstract: The present disclosure provides example line order detection methods and multi-antenna network devices. One example method includes obtaining preset antenna numbers of a target antenna group. A first uplink received signal strength sequence of each antenna channel is determined based on a first uplink reference signal sequence from a terminal. After an antenna downtilt angle of the target antenna group is adjusted from a first downtilt angle to a second downtilt angle, a second uplink received signal strength sequence of each antenna channel is determined based on a second uplink reference signal sequence from the terminal. Actual antenna numbers of the target antenna group are determined based on the first uplink received signal strength sequence and the second uplink received signal strength sequence of each antenna channel. When the preset antenna numbers are different than the actual antenna numbers, a line order is determined to be incorrect.

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.
