Embodiment Construction

[0017] The present invention will be further described below through specific embodiments.

[0018] In order to improve the efficiency of the traditional random fuzzy Fuzzing test, in order to reduce the number of useless test cases and improve the usability of test cases, the invention proposes a structure-oriented data structure mutation algorithm based on node cloning for IEEE802.15.4 protocol MAC layer data frames .

[0019] The main work of the IEEE802.15.4 protocol MAC layer includes: correctly sending and receiving physical layer data, and maintaining a database that stores the status information of the MAC layer protocol. According to IEEE802.15.4 protocol, refer to figure 1 , MAC layer data frame includes control field (frame control in the figure), sequence number field (sequence number in the figure), address field (destination PAN address, destination address, source PAN address and source address in the figure), data field ( Encrypted information in the figure), paylo...

Abstract

A data construction variation algorithm based on node clone is used for generating Fuzzing test cases. The data construction variation algorithm comprises the steps of on the basis of address information of nodes in the know network, arbitrarily selecting a node A and a node B which can be in direct communication in the network, taking the node B as a trust node of the node A, and replacing a destination address and a source address in a data frame address domain transmitted by a test device with addresses of the node A and the node B to perform node clone; backwards inferring a destination address mode and a source address mode in a frame control domain according to the destination address and the source address before replacement, and randomizing other bits in the control domain; calculating an FCS proof test value again and attaching the FCS proof test value to the tail of a data frame. By means of the data construction variation algorithm based on node clone, even though the quantity of test cases is reduced, availability of the test cases is improved greatly, and test efficiency is increased due to comprehensively considering a frame structure and data randomization.

Description

Technical field [0001] The invention relates to the technical field of safety detection of wireless sensor network (WSN) of IEEE802.15.4 protocol, in particular to a data structure mutation algorithm based on node cloning. Background technique [0002] The power Internet of Things uses wireless sensor networks (WSN) to provide information perception for smart grids such as infrastructure, and plays a huge role in power grid construction, grid safe production management, operation and maintenance, information collection, security monitoring, metering, and user interaction. Improve the depth, breadth and density of information perception in all aspects of the smart grid. The Institute of Electrical and Electronics Engineers (IEEE) developed a low-power wireless personal area network standard in 2003-05, namely the IEEE802.15.4 protocol. The agreement established the physical layer (PHY) and media access layer (MAC) specifications. At present, various organizations have formulated...
