Problems solved by technology

[0004] It can be seen that the proxy server in the traditional Internet of Things network cannot fully support the UDP protocol, or the UDP message cannot be encrypted when the SOCKS proxy protocol of the UDP protocol is supported, resulting in no security guarantee

Embodiment Construction

[0101] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of them. Based on the embodiments of the present application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0102] At present, the application of the Internet of Things and the access technology of the Internet of Things are developing rapidly, and among the emerging technologies of long-distance Internet of Things access, NB-IoT technology has some obvious advantages. Long-distance IoT access is an IoT access method that is very relevant to operators. In addition to traditional 2G and 4G access, there are emerging access methods such as NB-IoT. Currently, H...

Abstract

The embodiment of the invention discloses a method and a device for forwarding a user datagram protocol message. After a proxy server receives the identifier and the secret key authentication code sent by the Internet of Things equipment, when the identifier is consistent with the stored identifier and the secret key authentication code corresponding to the stored identifier is consistent with thesecret key authentication code. The service information of forwarding service is sent to the Internet of Things equipment. Based on the at least one password suite sent by the Internet of Things device, a target password suite is sent to the Internet of Things device. Then, a first UDP message sent by the Internet of Things device is received. After the first UDP message comprises the position information and the first data of the target service server, the first UDP message is decrypted based on the target password suite to obtain the position information and the first data of the target server. Finally, the first data is sent to the target service server corresponding to the position information, thereby realizing forwarding of the UDP message completely based on the UDP protocol, and improving the safety of the UDP message.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a method and device for forwarding a user datagram protocol message. Background technique [0002] The User Datagram Protocol (UDP) is a connectionless transport layer protocol in the OpenSystem Interconnection (OSI) reference model. Unlike the TCP protocol, the UDP protocol is connectionless. It does not need to maintain the order of receiving packets, nor does it need to maintain the sliding window, etc., so the implementation is much simpler; and because there is no need for three-way handshake to establish a connection, UDP packets can be sent immediately. So the sending delay is lower. The UDP protocol is widely used in IoT networks. For example, HiSilicon’s narrowband Internet of Things (Narrow Band Internet of Things, NB-IoT) chip only supports the UDP protocol, not the Transmission Control Protocol (TCP); Qualcomm and Taiwan MediaTek MTK's NB-IoT chi...
