Abstract: The present disclosure relates to a communication method, apparatus and system, an electronic device, and a computer readable storage medium. The communication method includes: determining an accepting host to be connected; obtaining a public key and communication address information of the accepting host from a blockchain; generating to-be-verified information according to the public key of the accepting host and a private key of the initiating host; sending the to-be-verified information to the accepting host according to the communication address information; and sending a communication connection request to the accepting host according to the communication address information to establish a communication connection with the accepting host. By adoption of the present disclosure, the anti-risk and anti-attack capabilities of the communication system may be improved by the decentralized features and security features of the blockchain, and the communication security is improved.

Abstract: The present disclosure relates to a data processing method and apparatus, a terminal and an access point computer, which can achieve an effect that the terminal accesses multiple access points at the same time. The method includes: receiving an application access request; determining a target access point corresponding to the application access request according to a mapping relationship between the access point and an application server obtained from a blockchain network; sending a software defined perimeter SDP authentication request to the target access point; and after the SDP authentication succeeds, performing interaction of application data through a data channel established with the target access point, wherein the data channel has a period of validity of a preset time length.
