Abstract

Technologies for attestation techniques, systems, and methods to confirm the integrity of a device for service discovery and more specifically, for proving trustworthiness of particular service devices and/or mDNS controller/network elements with respect to DNS/mDNS service discovery. Such attestation techniques may implement canary stamps (e.g., tokens or metadata elements containing or reflecting security measures taken at the device).
