Summary: | The invention discloses a secret-key pre-distribution method based on a three-dimensional matrix. According to the secret-key pre-distribution method, a secret-key pre-distribution guiding model based on the three-dimensional matrix is designed on the basis that different secret-key guiding models are researched according to the characteristics of a wireless sensor network. A plane of the three-dimensional matrix is in six types through the secret-key pre-distribution guiding model, and before actual deployment of sensor codes is carried out, the sensor codes and three-dimensional matrix coordinates correspond in a one-to-one mode through the secret-key pre-distribution guiding model, and then corresponding plane secret keys (an only plane secret key is shared between nodes of the two parallel planes) are stored respectively according to difference of six-type planes of the coordinates corresponding to the nodes; after the nodes are deployed, six same sharing secret keys of any two nodes can be found accordin |
