Description

Technical Field

[0001] The present invention relates to the field of network technology, and in particular to a broadband sensor network protocol consistency detection system and method, so as to realize protocol consistency detection of terminal devices, relay devices and network management devices. Background Art

[0002] A protocol is a series of specifications that ensure that each communication entity in a communication system can interact normally. Protocol consistency testing is an important aspect of protocol testing, which aims to detect the degree of compliance between the protocol implementation under test and the protocol specification. For the network architecture of broadband sensor networks, the protocol consistency detection system needs to support single-hop testing such as terminal communication parameter configuration, media access control channel scheduling, access authentication process, and packet fragmentation process, and also needs to support the node under test as a relay node for simulated access nodes and simulated aggregation nodes to complete the verification of the networking process and network topology.

[0003] The broadband sensor network adopts a three-way peer authentication model, such as Figure 1 As shown, the ternary peer-to-peer authentication mode includes five steps: ① The access point (master device) sends a message "Identity authentication starts" to the terminal (slave device); ② The terminal sends a reply to the access point "This is my identity information, please authenticate, and please show me your identity information and the third party's identity authentication result for you"; ③ The access point sends a message to the authentication server "This is the identity information of me and the terminal, please authenticate and feedback the result"; ④ The authentication server sends a message to the access point "This is the identity authentication result for you and the terminal", at which time the access point can determine whether the terminal identity is legal; ⑤ The access point sends the authentication result of the authentication server to the terminal. After receiving the authentication result, the terminal determines whether the identity of the access point is legal based on the previously received access point identity information and the authentication result of the authentication server.

[0004] When performing authentication, a multi-hop sensor network based on a ternary peer-to-peer authentication model requires the end devices at all levels to report authentication requests in order from bottom to top, and at the same time requires the end devices at all levels to authenticate in order from top to bottom. There are strict requirements for the communication process of authentication interaction, and no omissions are allowed in the devices at all levels. At present, there is still a lack of a consistency detection system and method for the multi-hop sensor network authentication protocol based on a ternary peer-to-peer authentication model.

[0022] The main controller 10 is configured to control the operation of the authentication management module 20. Specifically, the main controller 10 includes a power supply 11, a memory 12, a main board 13, and an operating system 14. The power supply 11 is connected to the memory 12 and the main board 13, respectively, and is used to supply power to all hardware devices. The memory 12 and the main board 13 are both connected to the operating system 14 in communication, and the operating system 14 supports the normal operation of the authentication management module 20.

[0023] The execution module 30 includes a simulated access node 31, a simulated aggregation node 32 and a simulated broadband terminal 33. The simulated access node 31, the simulated aggregation node 32 and the simulated broadband terminal 33 are all connected to the main controller 10 by wire, and are all wirelessly connected to the node 40 to be tested. The execution module 30 is configured to: use the node 40 to be tested as a relay node for the simulated access node 31 and the simulated aggregation node 32 to complete the verification of the networking process and network topology; at the same time, the simulated broadband terminal 33 is connected to the node 40 to complete the node-side consistency verification of the communication parameter configuration, media access control channel scheduling, access authentication process, and packet segmentation process. The execution module 30 is built with existing software for completing functions such as parameter configuration, selecting test items, storing messages, and detecting messages.
