DYNAMIC CERTIFICATE MANAGEMENT AS PART OF A DISTRIBUTED AUTHENTICATION SYSTEM

Abstract:

The disclosed technology is generally directed to embedded device updates. In one example of the technology, a request for a nonce from a device is received. The nonce is sent in response to the request. An authentication request that includes the nonce, a set of measurements associated with the device, and a cryptographic signature generated from a private key associated with the device is received. The device is validated based on the authentication request. In response to successful validation of the device, a short-term certificate is generated for the device.
