Monitorable privacy communication method based on secret sharing scheme

Abstract

The invention discloses a monitorable privacy communication method based on a secret sharing scheme. The privacy communication method comprises a user side, a service provider, and an monitor side. The user side comprises a sender and a receiver. Point-to-point communication or many-to-many communication between the sender and the receiver is adopted. A key agreement is performed between the sender and the receiver through a DH protocol. After the key agreement is completed, a session key formed is divided according to the number of the sender, the receiver, the service provider, and the monitor side, and the divided key is assigned to the sender, the receiver, the service provider, and the monitor side. Then, a group member encrypts the received divided key. The service provider receivesthe encrypted key and the assigned divided key. The monitor side receives the assigned divided key. According to the monitorable privacy communication method based on a secret sharing scheme, the contradiction between the privacy communication of users and the content monitoring from the service provider in the prior art can be solved; privacy communication of users can be protected to the greatest extent; and point-to-point and many-to-many monitorable privacy communication can be achieved.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a privacy-monitoring communication method based on a secret sharing scheme. Background technique [0002] Since the invention of the instant messaging tool, it has been widely used, but there are always irreconcilable contradictions in terms of user privacy security and service provider content supervision. The specific manifestation is that users want their communication information to be protected by privacy and refuse to be viewed by others; and service providers often need to review user communication information out of consideration for content security. [0003] Privacy security is currently a concern of citizens, especially for privacy protection in communication, which has become a hot topic of research and discussion. For private communication, there are currently mature private communication protocols, such as a protocol based on the RSA algorithm to exchang...

Problems solved by technology

However, it has more or less only one aspect of the function, that is, it either has private communication but does not have the method of reviewing the content, or the service provider stores the communication records in plain text to realize the function of content review and cannot avoid service provision. the possibility that the merchant will retain the communication records for other purposes

At this stage, no matter what kind of instant messaging tool, it is not possible to monitor the content under special circumstances on the basis of privacy protection
