Abstract

Techniques for manufacturing cryptographically-enabled network endpoints are described herein. In an example, an endpoint is provisioned with keys, which may include a revocation key, a command key, a recovery key and other cryptographic information. A buyer of the endpoint may send one or more keys to the manufacturer, and request that a handover package be sent by the manufacturer to the buyer. The manufacturer sends the handover package, which may include cryptographic information appropriately signed by the manufacturer. Upon receipt, the handover package is cryptographically processed by the buyer and portions are included in a takeover package sent to the endpoint. The endpoint may replace operational keys within the endpoint and switch its operation from use of manufacturer-produced credentials to use of buyer-produced credentials. Accordingly, the endpoint is provisioned for secure operation by the owner in an advanced metering infrastructure (AMI) or Internet of Things environment.
