Problems solved by technology

[0003] In 2004, the IETF established the 6LoWPAN working group to study the application scheme of IPv6 on the IEEE 802.15.4 network. At present, corresponding solutions have been proposed for the adaptation layer technology, header compression technology, and routing technology, but there is no provision for the security mechanism of the 6LoWPAN network. A set of effective methods, one of the security issues that must be paid attention to is the abuse of NDP (Neighbor Discovery Protocol), duplicate address detection and router announcement messages, etc.
However, this solution is not suitable for LoWPAN networks. Routers often need to provide certificate path chains, which requires the host to spend a lot of resources and energy to calculate the validity of the path. At the same time, the SEND protocol needs to use CGA for all ND messages ( Encryption generated address) and RSA public key system, which requires longer processing time and calculation process, is not suitable for sensor nodes with limited resource energy

Embodiment Construction

[0036]The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0037] The technical scheme of the present invention relies on the optimized 6LoWPAN network neighbor discovery process, realizes an effective node access control scheme, and provides security protection for the network. In the 6LoWPAN network, the border router plays an important role. In addition to connecting the WSN network to the Internet, it is also responsible for notifying the link prefix (subnet information) route and other configuration information, and maintaining the IPv6 address of each node within the network range. information and MAC information, so that it can perform two-layer address resolution and duplicate address detection. The border router needs to be manually configured, such as figure 1 shown.

Abstract

The invention discloses a LoWPAN (low-power wireless personal area network) node secure access control method based on neighbor discovery. The LoWPAN node secure access control method based on neighbor discovery solves the problem of communication security of 6LoWPAN (IPv6over LoWPAN) links. By means of optimization on RS (router solicitation) and RA (router advertisement) messages in a router discovery protocol, security authentication when new nodes are added into a network is achieved effectively, and whether the messages in the network are tampered or not is detected. By means of secure access control of a new node, an authentication address IP (internet protocol) list is maintained commonly within a network range, and attack and masking of malicious nodes can be prevented within the whole network range. The LoWPAN node secure access control method based on neighbor discovery has the advantages that the method is put forward based on an NDP (neighbor discovery protocol) of the 6LoWPAN, redefining new protocol types is not needed, and the method is higher in extendibility, easier to popularize and particularly applicable to sensor networks limited in resource energy.

Description

technical field [0001] The invention relates to a control method for secure access of 6LoWPAN nodes, belonging to the technical field of wireless sensor network security. Background technique [0002] The wireless sensor network is a wireless network composed of a large number of micro-nodes integrated with sensors, data processing units and communication modules randomly distributed on demand in a self-organizing manner. It has the advantages of low cost, low energy consumption, and high flexibility. It can be applied to It has important research value and application prospect in the fields of national defense and military, environmental monitoring, traffic management and so on. As a next-generation network protocol, IPv6 has the advantages of rich address resources, automatic address configuration, good mobility and scalability, and can meet the needs of wireless sensor networks in terms of address, security, mobility, and integration with existing networks. [0003] In 2...
