Abstract: A secure processor for a post-quantum cryptography (PQC) algorithm CRYSTALS-KYBER, includes a communication unit, a management unit, a processing unit, and a storage unit. The communication unit is configured to receive and transmit data for the secure processor; the management unit is configured to control the processing unit according to the data; the processing unit is configured to process the data to form encrypted data, decrypted data and key data; and the storage unit is configured to store all data. The secure processor can efficiently and rapidly realize key generation, encryption and decryption of a KYBER algorithm under KYBER1024, KYBER768 and KYBER512 security levels, makes data encryption more complicated, and ensures security of the data.

Abstract: An oil circulation system is configured to supply lubrication oil to a plunger pump. The oil circulation system includes an oil tank, and the oil tank is provided with an electric heater. The oil circulation system further includes: a main circulation circuit. Two ends of the main circulation circuit are configured to respectively communicate with an oil outlet and an oil inlet of the oil tank, and the main circulation circuit is provided with a power member; and an overflow valve, disposed on the main circulation circuit and located on an oil outflow side of the power member.

Abstract: The technology of this application relates to the field of filter technologies, and provides a common mode filter and a terminal device. The common mode filter includes a first winding and a second winding. A portion of the first winding and a portion of the second winding are formed, by rotating around a same axis, at a first coil layer. The other portion of the first winding and the other portion of the second winding are formed, by rotating around another same axis, at a second coil layer stacked with the first coil layer. At the first coil layer and the second coil layer, there is one turn of the second winding between each two adjacent turns of the first winding.
