Embodiment Construction

[0040] The preferred embodiments of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0041] In this embodiment, the wireless sensor network is composed of a base station and a large number of randomly deployed sensor nodes, such as figure 1 shown. The base station is responsible for basic work such as integer pool generation and integer pre-allocation. Wireless sensor nodes complete key construction and sensor node deletion and addition under the effective control of the base station.

[0042] This embodiment follows figure 2 The steps shown implement the key agreement:

[0043] According to step 1, generate an integer pool and perform integer pre-allocation:

[0044] like image 3 As shown, first, the base station determines an integer N according to actual application requirements and pre-calculation, such as N=2 or N=3, and this integer is used for subsequent integer modulo, and at the same time, the base stati...

Abstract

The invention relates to a wireless sensor network key management method based on integer modulo, and belongs to the field of network communication security. It includes the following steps: generate an integer pool and pre-allocate integers; construct a session key between sensor nodes; after the session key is constructed, each sensor node stores a table data, and the table data mainly records other information that the sensor node can communicate with. Sensor nodes and corresponding session keys; determine whether there is a deletion or addition of sensor nodes, and if so, update the table data of the sensor nodes to build a secure remittance path. The invention reduces the session key that each sensor node needs to store, and is beneficial to the dynamic expansion of the entire network; at the same time, it greatly reduces the storage requirement and communication load in the session key construction stage.

Description

technical field [0001] The invention relates to a wireless sensor network key management method based on integer modulo, and belongs to the field of network communication security. Background technique [0002] Wireless sensor networks are referred to as WSNs, that is, Wireless Sensor Networks. Wireless sensor networks have been widely regarded as one of the most important technologies in the 21st century. With the development of wireless communication and micro-electromechanical system technology, sensor nodes can be made cheap, small and It is intelligent and can provide a wide range of military and civilian applications such as battlefield reconnaissance, industrial control and environmental monitoring through wireless connection to the Internet. [0003] Due to the typical characteristics of wireless sensor networks, there are many challenges in the design process of wireless sensor networks. It is mainly reflected in the following aspects: 1. Limited node energy: senso...
