A trust web keying process provides secure peer networking of computing devices on an open network. A device is initially keyed at distribution to an end user or installer with a device-specific cryptographic key, and programmed to respond only to peer networking communication secured using the device's key. The device-specific key is manually entered into a keying device that transmits a re-keying command secured with the device-specific key to the device for re-keying the device with a group cryptographic key. The device then securely peer networks with other devices also keyed with the group cryptographic key, forming a trust web. Guest devices can be securely peer networked with the trust web devices via a trust web gateway.
