Communication protocol testing method and system for smart home equipment

Abstract

The invention provides a communication protocol test method of intelligent household equipment and a system thereof. The method comprises the following steps of acquiring a data packet between a detected object and an opposite end system based on a protocol session; carrying out protocol analysis on the data packet and determining whether a communication protocol used by the detected object is a known protocol; when the communication protocol used by the detected object is a non-known protocol, acquiring a variable field of the data packet; according to the variable field, carrying out mutation operation on the data packet sent to the detected object from the opposite end system based on the protocol session and generating a test case of the detected object; and sending the test case to the detected object so as to execute and monitoring whether the detected object generates an abnormity. The communication protocol test method and the system thereof of the invention are suitable for an intelligent household system communication protocol; and aiming at privately-owned, encrypted and other characteristics of an intelligent household protocol, a protocol knowledge base containing an known protocol model and an abnormal test case generation rule and an encryption algorithm knowledge base are introduced so that protocol analysis efficiency is effectively increased and testing of an encryption protocol is supported.

Description

technical field [0001] The invention relates to the technical field of testing smart home equipment, in particular to a communication protocol testing method and system for smart home equipment. Background technique [0002] With the rapid development of technologies such as the Internet of Things and big data analysis, smart home devices are more and more widely used, bringing great convenience to daily life. At the same time, as a consumer field that is closely related to consumers' lives, the security threats it faces are becoming more and more serious. The types of network attacks against smart homes are constantly being updated and incidents emerge in endlessly. Communication protocols are important for the interconnection and interoperability of smart home devices. link, its security testing has attracted more and more attention from the industry. [0003] As the rules and agreements that must be followed to complete communication or services between smart home nodes,...

Problems solved by technology

[0009] At present, there is no special tool for security analysis and testing of smart home system communication protocols in China

Moreover, there is no effective solution for fuzzing testing of private or encrypted communication protocols. Generally, it is only possible to rely on manual reverse analysis of the protocol, which is very inefficient.

[0010] For the traditional testing of private protocols, the non-intelligent fuzzing test method based on mutation is generally selected. Although this can avoid the difficult process of protocol analysis, due to the lack of understanding of the protocol itself, it may cause a large number of data packets due to blind construction of data packets. Invalid test cases, thus greatly reducing test efficiency

As for the encryption protocol, the traditional method can only decrypt it first through reverse analysis. High consumption
