Abstract

The present invention provides a retransmission method based on a finite state machine. The retransmission method is based on partial retransmission technology. The client and the server use a finite state machine, wherein the finite state machine includes three states: working, inquiry and pause. When data packets are lost during user data transmission, the data packets are retransmitted through the conversion of three states, which improves the quality of information transmission, enhances the security of data transmission, and prevents channel congestion and user information from being stolen. By establishing the main algorithm model and the reference algorithm model, the success rate, delay and security of the data retransmission method are investigated to achieve the goal of verifying the effectiveness of the retransmission method based on the finite state machine.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method for retransmitting user information data. Background technique [0002] At present, in the various processes of user authentication, whether it is one-way or two-way authentication, the main authentication communication steps can be roughly divided into four steps (C means client, S means server): [0003] (1) C→S, authentication request (user serial number) [0004] (2) S→C, impact code 1 [0005] (3) C→S, response code 1. If it is biometric authentication, plus biometric information. If it is two-way authentication, plus shock code 2 [0006] (4) S→C, whether to pass or not. If it is two-way authentication, plus response code 2 [0007] In the case that the connection cannot be maintained, packet loss may occur in any of the above four steps. In view of this situation, most systems adopt the common state machine model of the server and the user. The transmi...
