Abstract

Disclosed are an information processing method, retrieving method, device, user terminal and server, the retrieving method comprising: a first user terminal receives the address information transmitted by a second user terminal for saving an encrypted file of the user of the second user terminal; acquiring the private information, the non-private information and a shared key corresponding to the address information from a cloud server and a trusted server; acquiring the address information of a file to be accessed by retrieving the private information and the non-private information; acquiring from the cloud server a first encrypted file corresponding to the address information of the file to be accessed; decrypting, via the shared key, the first encrypted file to acquire the file to be accessed. The present invention introduces a trusted server during the information retrieval process, such that an encrypted file uploaded to a cloud server by a user terminal can be retrieved by a trusted third-party user terminal, thus taking full advantage of the cloud server performance while ensuring user file security.

Description

technical field [0001] The present invention relates to the technical field of network communication, and in particular, to an information processing method, a retrieval method, a device, a user terminal and a server. Background technique [0002] Cloud computing is a technology that provides dynamic and easily scalable virtualized resources through the Internet. Through cloud computing, the network can be easily accessed, and by configuring a large number of storage devices, the storage and management of massive data can be realized. [0003] Cloud computing usually requires a lot of user participation. Users can upload their own files to the cloud server for storage. At this time, the user's files may be open to the outside world, and third-party users can retrieve the required files from the cloud server. Therefore, in order to protect the privacy and security of the user's files, the user usually encrypts the file before uploading it to the cloud server, and uploads the ...
