Abstract: Systems, methods, and computer readable media are described herein that use a user-agent-based non-extractable cryptographic keypair to generate a cryptographic proof containing a device fingerprint that an authentication system can use to subsequently identify and/or register a known device. Specifically, the systems disclosed herein may generate the device's “fingerprint” in an isolated and secured environment. Although the private key cannot be extracted from the isolated and secured environment, the authentication system can verify the truthfulness of the device's identity. This cryptographic “fingerprint,” in concert with a synchronous authentication system, has the ability to essentially eliminate authentication phishing.
