2results about How to "Improve security protection efficiency" patented technology

This application discloses a security protection method and related products. The method includes: identifying abnormal behavior in the data to be processed corresponding to a target vehicle based on a preset security rule base and a pre-trained anomaly recognition model to obtain a security recognition result; if the security recognition result indicates a first anomaly level, then performing local security protection on the target vehicle according to a local protection strategy; if the security recognition result indicates a second anomaly level, then obtaining the collaborative protection strategy sent by the cloud platform corresponding to the target vehicle, and performing collaborative security protection with other vehicles according to the collaborative protection strategy. This improves the security of the entire vehicle-to-everything (V2X) environment.

This application relates to a data encryption method, a risky data processing method, an apparatus, a computer device, and a storage medium. The method includes: acquiring application source code data; compiling the application source code data to obtain first application compiled data; replacing the signature encryption public key in the first application compiled data with a simulated public key to obtain second application compiled data. If a data encryption request is received, the method acquires the data to be processed corresponding to the data encryption request, restores the second application compiled data to the first application compiled data, and performs encryption and signature processing on the data to be processed based on the signature encryption public key in the first application compiled data to obtain encrypted signature data. This method can reduce the risk of leakage of the signature encryption public key, as well as information leakage and resource loss to the platform and users, and improve the efficiency of information security protection.
