  • Patent number: 12255981
    Abstract: The present disclosure provides methods and apparatuses for implementing high-speed cryptographic operations based on software-hardware collaboration, and electronic devices. In the embodiments of the present disclosure, by analyzing software and hardware computing resources in real-time, the cryptographic device driver allocates the one or more target resources for cryptographic computation to the reference data packets. When the one or more target resources include the target cryptographic device, the cryptographic device executes, according to the characteristics of the target cryptographic algorithm used to perform cryptographic computation on the reference data packet, the acceleration operation corresponding to the target cryptographic algorithm for the cryptographic computation on the reference data packets, such as grouping the reference data packets, to improve a concurrent execution rate of an algorithm and cope with situations with a large amount of service concurrency and data processing.

  • Patent number: 9159928
    Abstract: Disclosed are an amine-oxide-group-containing conjugated polymer photoelectric material and application thereof. The amine-oxide-group-containing conjugated polymer photoelectric material consists of conjugated main chains and a side chain containing an amine oxide unit, and is applied in an organic photoelectric device. The material has desirable alcohol/water solubility and photoelectric properties, is suitable for making a multi-layer solution for machining a device, and meanwhile can prevent an adverse effect incurred by freely moving counter ions in a common polyelectrolyte to the device. The material may be used as a cathode interface modification layer applied in organic photoelectric devices such as light-emitting and photovoltaic devices, so as to improve performance of the devices.
