Digitalization has generated massive amounts of data for various industries.The effectiveness and convenience of some data require it to be stored in the cloud.Thus,the security of data stored in the cloud has become an important concern for people.A secure cloud storage system for data is designed and imple-mented based on Android system and the hybrid encryption algorithm of SM2 and SM4.The system adopts a C/S architecture and implements file management functions through software encryption and decryption.Through testing and use on Pixel 3 devices,the results show that it runs well and achieves the security and effectiveness of new media user data storage.This system improves the security of cloud data and effectively solves the privacy issue of user cloud disk storage files.
