Device access processing method, device access processing device and terminal

Abstract

The invention discloses a device access processing method, a processing device and a terminal. The processing method comprises following steps: when the terminal receives a device access request from a to-be-accessed device, sending a first random code to the to-be-accessed device; after the to-be-accessed device receives the first random code, calculating a first target key according to the first random code, a pre-stored second random code and a pre-stored first public key; sending the first target key to the terminal; receiving a second random code and the first target key from the to-be-accessed device; calculating a second target key according to the first random code, the second random code and a pre-stored second public key; judging whether the second target key and the first target key are the same; if the judging result is yes, allowing the to-be-accessed device to access a wireless body area network, or forbidding the to-be-accessed device to access the wireless body area network. The technical solution of the invention is general, is low in calculation quantity and can carry out security authentication to the access device in the wireless body area network efficiently.

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, 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. It consists of a set of small and movable sensors with communication functions and a body Composition of the main station. 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 ...

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
