An Inspectable Privacy Communication Method Based on Secret Sharing Scheme

Abstract

A monitorable privacy communication method based on a secret sharing scheme. The privacy communication method includes the user side, the service provider and the monitoring side. The user side includes the sender and the receiver. The sender and the receiver use point-to-point communication or In many-to-many communication, the sender and receiver conduct secret key negotiation through the DH protocol; after the secret key negotiation is completed, the session key will be formed according to the sender, receiver's team members, service provider and monitoring Split the secret key according to the number of parties; distribute the split secret key to the sender, receiver team members, service provider and supervisor, and the team members encrypt the received split secret key; the service provider Receive the encrypted key of the group members and the assigned split key; the monitoring party receives the assigned split key. The invention solves the contradiction between the existing user's private communication and the service provider's content monitoring, protects the user's private communication to the greatest extent, and realizes point-to-point and many-to-many private communications that can be monitored.
