Internet-of-things terminal equipment communication protocol consistency security detection method

Abstract

The invention discloses an Internet-of-things terminal equipment communication protocol consistency security detection method. The method comprises the following steps: 1, generating a formal description model for a communication protocol standard state machine; 2, generating a corresponding test case set based on the unique input / output sequence according to the formal description of the protocolstandard state machine, and further converting the test case set into an executable protocol interaction test case set according to the specific conditions of the detection environment and the testedequipment; and 3, executing the executable test case set, observing the external response of the tested equipment, carrying out content conformance judgment on the response output of the tested equipment, and judging whether the response output of the tested equipment is the same as the expected output of the protocol standard. According to the method, whether the communication protocol implementation of the Internet-of-things terminal equipment does not accord with the protocol standard can be rapidly detected, and potential safety hazards can be found in time.

Description

technical field [0001] The invention relates to a communication protocol security detection method, in particular to a consistency security detection method for a communication protocol of an Internet of Things device. Background technique [0002] With the rapid growth of the number of connected devices in the world, "Internet of Everything" has become an important direction for the future development of the global network. It is predicted that by 2025, the number of global IoT devices connected to the Internet will reach 25.2 billion, which will be widely used in many fields such as smart cities, smart transportation, smart production, and smart homes. At the same time, a series of security issues and threats related to it are also increasingly concerned by people. [0003] In the specific implementation process of the Internet of Things system, the consistency security detection of the communication protocol of the terminal equipment is an indispensable organic part.

Problems solved by technology

[0005] 1. The vulnerability of the communication link: The data transmission of the Internet of Things generally communicates by means of wireless radio frequency signals. The inherent vulnerability of wireless networks makes the system vulnerable to various forms of attack and interference

Attackers can transmit interference signals so that the reader cannot accept the data in the normal electronic tag, or the base station cannot work normally, causing communication interruption, and the communication status between the IoT terminal device and the remote server is out of sync, resulting in communication failure;

[0006] 2. Vulnerability of communication links: due to the development of wireless links, it is easy for attackers to invade the network by hijacking channels

However, there is no targeted testing method for the above-mentioned specific consistency security issues faced by the IoT terminal device communication protocol, and the traditional basic interconnection detection, capability detection, and behavior detection methods cannot effectively find the IoT terminal device in the face of Consistency security issues arising from asynchronous communication status and receipt of communication protocol messages containing malicious fields
