The automated inspection vehicle in industrial settings conducts data collection via IoT devices.Nevertheless,current control systems for these vehicles transmit data in plain text,leaving them vulnerable to security threats like data leaks.Conventional encryption algorithms can only access data post-decryption,leading to reduced execution efficiency.Hence,this paper introduces a novel searchable encryption algorithm that facilitates the application of symmetric encryption algorithms for data encryption and decryption operations.This allows data users to perform ciphertext retrieval func-tions,thereby improving both data security and usability.Furthermore,this paper employs the afore-mentioned algorithm to establish a security protection system for automated inspection vehicles,effec-tively ensuring data security.
