IoT DATA MANAGEMENT SCHEME BASED ON PROXY RE-ENCRYPTION IN IoT LIGHTWEIGHT DEVICES AND SYSTEM

摘要

The present invention discloses a data management method and system based on proxy re-encryption in IoT lightweight terminal environment. Proxy re-encryption based data management method in the IoT lightweight terminal environment according to an aspect of the present invention, by providing a terminal management method based on the proxy re-encryption method, only the user trusted in the step of managing the re-encryption key The received data can be decrypted using the private key. In addition, the number of communication increases in the data encryption transmission process can be lowered by using re-encryption, as compared with the existing terminal-to-device encryption communication method.
