Dynamic encryption communication method and confidential conference room thereof

The invention belongs to the technical field of encryption communication, and particularly relates to a dynamic encryption communication method and a confidential conference room thereof, and the dynamic encryption communication method comprises the steps: carrying out the identity verification of communication participants through employing an improved zero-knowledge proof technology, and starting the real-time communication after all communication participants complete the identity verification; encrypting original data sent by a sender by using a homomorphic encryption algorithm, and decrypting the received encrypted data by a receiver by using a private key to obtain decrypted data; each communication participant allocates a pair of public key and private key, the public key is registered on a block chain, and the block chain records a mapping relationship between the public key and the identity information of the communication participant; according to the invention, the security of identity verification
