Abstract
Embodiments of the present invention are directed toward authentication systems, devices, and methods. Obfuscated executable instructions may encode an authentication procedure and protect an authentication key. The obfuscated executable instructions may require communication with a remote certifying authority for operation. In this manner, security may be controlled by the certifying authority without regard to the security of the electronic device running the obfuscated executable instructions.
