DATA TRANSMISSION METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240022775 titled 'DATA TRANSMISSION METHOD AND APPARATUS
Simplified Explanation
The patent application describes a method and apparatus for improving the security of audio-video data transmission. It involves identity authentication and key negotiation between the source device and a transmission device that needs to output or process the audio-video data. A key distribution packet is generated by the source device to encrypt or decrypt the audio-video stream exclusively for the transmission device. Other devices on the transmission path cannot access the key or perform decryption, enhancing the transmission security of the audio-video stream. The source device also performs identity authentication and authorization control on other transmission devices that need to output or process the audio-video data.
- The method and apparatus improve the security of audio-video data transmission.
- Identity authentication and key negotiation are performed between the source device and the transmission device.
- A key distribution packet is generated to encrypt or decrypt the audio-video stream exclusively for the transmission device.
- Other devices on the transmission path cannot access the key or perform decryption.
- The source device also performs identity authentication and authorization control on other transmission devices.
Potential applications of this technology:
- Secure transmission of audio-video data in video conferencing systems.
- Secure transmission of audio-video data in surveillance systems.
- Secure transmission of audio-video data in multimedia streaming services.
Problems solved by this technology:
- Unauthorized access to audio-video data during transmission.
- Potential interception and decryption of audio-video data by unauthorized devices.
- Lack of centralized identity authentication and authorization control in audio-video data transmission.
Benefits of this technology:
- Enhanced security and privacy of audio-video data during transmission.
- Prevention of unauthorized access and interception of audio-video data.
- Centralized identity authentication and authorization control for improved security.
Original Abstract Submitted
a data transmission method and apparatus are provided, to improve security of audio-video data transmission. in this application, the source device performs identity authentication on and negotiate a key with a transmission device that needs to output audio-video data or perform transformation processing on a transmission path to the sink device, and generates a key distribution packet used to encrypt or decrypt an audio-video stream only for the transmission device that needs to output audio-video data or perform transformation processing. another device on the transmission path cannot know the key and cannot perform decryption, so that transmission security of the audio-video stream can be improved. in addition, the source device centrally performs identity authentication and authorization control on other transmission devices that need to output the audio-video data or perform transformation processing.
