Abstract
A method for performing proxy transformation between a user and a server includes: selecting a first proxy relationship between a target user and a first user from a proxy relationship library; selecting a random value, and generating a second proxy relationship according to the random value and the first proxy relationship; and encrypting original information according to the public key of the first user and the random value to obtain the encrypted information, and transmitting the encrypted information and the second proxy relationship to the server, so that the server performs proxy transformation on the encrypted information according to the second proxy relationship to obtain the transformed information. The method for performing proxy transformation thoroughly solves the security hazard that the server performs proxy transformation without user permission. The present invention further discloses a user terminal and a system for performing proxy transformation.
