Abstract: A seal assembly which includes a combination of an outer sleeve and an inner sleeve, which has a low friction sliding interface, such that the seal assembly provides desired sealing force and frictional force characteristics. When assembled, the seal assembly surrounds a rotor, such that the seal assembly is disposed between the outer surface of the rotor and the inner surface of a housing. The inner sleeve includes one or more ribs which are in contact with the outer surface of the rotor, which concentrates the sealing in the area of the ribs. The concentration of the sealing reduces the total friction between the rotor and the inner sleeve, while maintaining proper sealing force. The ribs formed as part of the inner sleeve are spaced apart such that the openings of the rotor are positioned relative to the ribs in a desired manner, regardless of the orientation of the rotor.

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.
