Problems solved by technology

However, this requires all nodes to have the ability to perceive the same signal (EEG or ECG, etc.), which puts forward new requirements for node hardware; Difficult to have the same accuracy, that is to say, the accuracy of key recovery cannot be guaranteed

Embodiment Construction

[0031] The present invention will be further described below in conjunction with accompanying drawing.

[0032] Such as figure 1 Shown is the general BSN structure of the present invention, the square node in the figure is the Sink node (ID=0), it is assumed that:

[0033] (1) Yes sensor nodes (Nodes 1~16 are shown in the figure) Deployed on the warded person (generally speaking, in the BSN ), each node has a unique (greater than 0), the nodes are not related to each other (each node can independently determine the perceived data);

[0034] (2) have Sink node, its =0, collect the data sensed by all sensor nodes, which is safe in itself;

[0035] (3) The Sink node has enough power to transmit data to all sensor nodes in one hop. The sensor node uses low-power short-distance transmission (good for the human body) to transmit the perceived data to the Sink node in a multi-hop manner. data;

[0036] (4) Each node (including Sink) in BSN pre-installs a network key , ...

Abstract

The invention discloses a method for generating pairwise keys. The invention utilizes the inherent node attributes of nodes, that is, the clock progress frequency (microsecond level) of a single node, and the clock skews of two nodes are different. Through secure Two microsecond-level timestamps at random intervals broadcast by the Sink node, the two nodes exchange information once, forming a unique pairwise key (Pairwise Key) between the two nodes that does not need to be distributed and is not easy to crack, and satisfies the "plug and play" use".

Description

technical field [0001] The invention relates to a method for generating a pairwise key (Pairwise Key) between nodes in a body sensor network BSN (Body SensorNetworks) multi-hop data transmission based on the clock offset of sensor nodes, in particular to the clock offset and clock progress of nodes A symmetric key generation method for attributes such as frequency and its application in encrypted data transmission. Background technique [0002] The wireless body sensor network BSN (Body Sensor Network), also known as the wireless body area network BAN (BodyArea Network), is a network that is worn on the body of the ward to monitor human physiological data, and its sensor nodes pass through one or more hops The perceived data is transmitted to the gateway node of BSN (or Sink node, which can directly transmit the data to PC or PDA), and provides physiological data to the wards (the elderly, infants, athletes, disabled and chronically ill) real-time monitoring. As the world'...
