Methods, systems, apparatuses, and devices for securing network communications using multiple security protocols

Abstract

The disclosed embodiments describe a data exchange method, apparatus, and device. In one embodiment, the method is applied to a sender device performing data exchange with a receiver device and comprises: negotiating a default protocol for the data exchange with the receiver device; obtaining a dynamic protocol according to the default protocol; generating an exchange data packet according to the dynamic protocol and to-be-transmitted data; and transmitting the exchange data packet to the receiver device, so that the receiver device receives the exchange data packet using the dynamic protocol generated through the default protocol. By means of the disclosed embodiments, a dynamic protocol is generated through a negotiated default protocol between a sender and a receiver; and data exchange is performed based on the dynamic protocol. Because the dynamic protocol can be dynamically generated when a need for data exchange arises, a malicious third party stealing can be effectively prevented in a communication process of data exchange, thereby enhancing data exchange security.
