Device access processing method, device access processing device and terminal

Abstract

The present invention proposes a device access processing method, a processing device, and a terminal, wherein the processing method includes: when the terminal receives a device access request from the device to be accessed, sending the first request to the device to be accessed A random code. After the access device receives the first random code, it calculates the first target key according to the first random code, the pre-stored second random code and the pre-stored first public key, and uses the second A target key is sent to the terminal; receiving the second random code and the first target key from the device to be accessed, and calculating the second Target key: judging whether the second target key is the same as the first target key, and if the judgment result is yes, allow the device to be accessed to access the WBAN, otherwise, prohibit access to the WBAN. The technical scheme of the invention is general, has low calculation amount, and can efficiently perform security authentication on the access equipment in the wireless body area network.

Description

technical field [0001] The present invention relates to the technical field of terminal access authentication, in particular to a device access processing method, a device access processing device and a terminal. Background technique [0002] WBAN (Wireless Body Area Network) is a short-distance wireless network centered on the human body. Specifically, it is a network attached to the human body. and a body master. As an emerging technology, wireless body area network has very broad application prospects in the fields of medical treatment, health care, and consumer electronics. In order to prevent malicious nodes from accessing the WBAN and then attacking and destroying the WBAN, the devices accessing the WBAN must be authenticated. At present, in the existing technical solutions, there are mainly three authentication methods: [0003] 1) An authentication method is: WBAN body subject (such as a terminal) and an external access device (such as a sensor) conduct two-way id...

AI Technical Summary

Problems solved by technology

However, this method is to determine that the node to be accessed is close enough to the WBAN through the signal strength, so as to authenticate it, without considering that the attacker may place malicious attack nodes around the WBAN user (for example, in front of and behind the seat)

[0006] The above three authentication methods realize the authentication between the WBAN and the access device under certain conditions, but each has its own defects: or the authentication operation is cumbersome, or limited, or the security is not enough
