Sensor network equipment safety communication encryption mechanism based on OID coding and addressing method

Abstract

The invention discloses a wireless sensor network communication method, system and user control terminal based on OIDs. A wireless sensor network comprises access devices and terminal devices, each access device is used for providing access communication for a secondary sensor network comprising at least one terminal device, both the access devices and the terminal devices store enterprise OIDs, MIDs, WIDs, NIDs and NPASSes, the NIDs and the NPASSes belong to the secondary sensor networks, and communication addressing and migration are conducted on the basis of address codes. Unique identification of the devices is set on the basis of OID coding, sub-network identification and sub-network secret keys are simultaneously introduced in to assist in addressing and encrypting of sensor network communication, communication safety and unique addressing are guaranteed, and meanwhile addressing speed and communication safety and reliability are improved.

Description

technical field [0001] The present invention relates to the technical field of wireless sensor networks, in particular to a secure communication encryption mechanism and addressing method for sensor network devices based on OID coding, and in particular to a wireless sensor network communication method and system based on object identifier (OID) coding and user console. The method can be used for unified identification and communication addressing of wireless sensor network equipment, while ensuring the uniqueness of wireless sensor network equipment identification, and at the same time ensuring the reliability of wireless sensor network equipment communication with the minimum communication overhead. Security and flexibility. Background technique [0002] Object Identifier (OID) is an identifier used to identify the unique identity of an object in a network communication or information processing system, and is the ID card of an "object". Through OID, we can get the relev...

Problems solved by technology

[0004] With the development of the Internet of Things industry, the demand for Wireless Sensor Network (WSN) products is increasing, but the existing wireless sensor network devices still use traditional coding methods or Therefore, these coding and addressing methods cannot adapt to the application characteristics of wireless sensor networks, resulting in problems such as data redundancy, low communication efficiency, and poor security.

[0005] For example, most of the products based on the ZigBee protocol widely used at present are a set of encoding methods formulated by the manufacturers themselves. recognized

[0006] On the other hand, the identification and addressing methods of some wireless sensor network equipment adopt the protocol standard of IPv6. Although this method can guarantee the uniqueness of equipment identification and can be recognized by international organizations, the complexity of its communication data, The efficiency of wireless sensor network communication is greatly reduced

Applying IPv6 technology to wireless sensor networks has the disadvantages of large IPv6 packets, heavy packet header load, complex address translation, easy to cause packet flooding, high resource requirements for routing methods, and does not support multicast function and network configuration. Complicated and other defects

[0007] The existing communication methods have adverse effects on the addressing, device migration and encryption of sensor network devices
