  • Simplified secure symmetrical key management
    Patent number: 8588410
    Abstract: Nodes of a network are each provided with a seed value and a seed identifier. Each seed value has a corresponding unique seed identifier which is maintained within the system. Within each authorized node, the seed value is combined with a local node identifier, such as a serial number or other unique identifier, to form a cryptographic key that is then used by the node to encrypt and/or decrypt data transmitted and received by that node. The cryptographic key is never transmitted over the network, and each node is able to create a different cryptographic key for use in communicating with other nodes.
