A dynamic orchestration-based audio-video security protection method is provided. A security sharing gateway identifies a level of audio-video data in an audio-video code stream and an authority of an audio-video retrieval platform before forwarding the audio-video code stream to the audio-video retrieval platform. In a case where the security sharing gateway does not retrieve a platform authority corresponding to the level of the audio-video data, it reports alarm information to a network and data security situation awareness platform. The network and data security situation awareness platform issues a platform authority corresponding to the level of the audio-video data to the security sharing gateway according to the alarm information, and in a case where it is determined that the level of the audio-video data does not match the authority of the audio-video retrieval platform, dynamically adjusts a security protection strategy of at least one other gateway in the system.

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.
