Abstract
A key distribution method is provided. The method is adapted for a network. The network comprises a plurality of nodes. In the key distribution method, a plurality of keys are provided to each node. A plurality of blocks are provided, serving as platforms. An algorithmic parameter is selected and a plurality of key parameters are provided to establish a balanced incomplete block (BIB) design area. One of the nodes broadcasts key parameters. The method can reduce the number of the key transmission, fast establish common keys, and reduce the network bandwidth for distributing the keys.

A key distribution method, adapted for a network, the network comprising a plurality of nodes, the key distribution method comprising:
- providing a plurality of keys to each of the nodes;
- providing a plurality of blocks as platforms of the nodes;
- selecting an algorithmic parameter, and providing a plurality of key parameters to establish a balanced incomplete block (BIB) design area;
- broadcasting the key parameters from one of the nodes;
- receiving from the key parameters by each of the nodes to reestablish the BIB design area;
- calculating common key channels between every two nodes;
- and
- combining the common key channels to generate common keys between every two nodes.
