Embodiment

[0036] The invention discloses a dynamic encryption method for UDP communication, including a UDP server design process and a UDP client design process;

[0037] Described UDP service end design flow comprises command port thread design flow and data port thread design flow;

[0038] Such as figure 1 As shown, the command port thread design process includes the following steps:

[0039] Step S101: creating a thread for the UDP command port;

[0040] Step S102: the command port monitors the client request, if there is a request message, immediately jump to step S103;

[0041] Step S103: use the public password KP to decrypt;

[0042] Step S104: Judging whether the request of the requesting client is correct, if it is a password request, jump to step S105, otherwise jump to step S102;

[0043] Step S105: dynamically generate the password K1 and return to the client, and then jump to step S102;

[0044] Such as figure 2 As shown, the data port thread design process include...

Abstract

The invention discloses a method for realizing dynamic encryption of UDP communication. The method comprises a UDP server design process and a UDP client design process. The UDP server design process comprises a command port thread design process and a data port thread design process; the method comprises the steps that firstly, a UDP server side is started, a command port thread and a data port thread are created at the same time, the command port thread mainly exchanges dynamic passwords with a UDP client side, and the data port thread is mainly responsible for data communication with the UDP client side; when the UDP client is started, a thread of a command port is created firstly, a password request message is sent to the server side, when the server side receives the password request message of the client side, a password is returned to the client side, the client side receives a dynamic password of the server side, and a data port is created to normally interact data information with the server side. The safety of the whole system is enhanced, illegal control is effectively prevented, and the reliability and the stability of the whole system are greatly improved.

Description

technical field [0001] The invention relates to the technical field of smart home, in particular to a dynamic encryption method for UDP communication. Background technique [0002] In industrial control applications, security control is very important. At present, many on-site controls are not encrypted and are easily destroyed, such as MODBUS, bacnet and the like. The dynamic encryption method proposed by the invention improves the security of the whole system. Contents of the invention [0003] In view of this, in order to solve the above-mentioned problems in the prior art, the present invention proposes a dynamic encryption method for UDP communication. [0004] The present invention solves the above problems by the following technical means: [0005] A method for implementing dynamic encryption for UDP communication, including a UDP server design process and a UDP client design process; [0006] Described UDP service end design flow comprises command port thread de...
