Abstract
Embodiments of the invention may provide for systems and methods for secure authentication. The systems and methods may include receiving, by a constrained device, a random string transmitted from a server; determining, by the constrained device, a responsive output by evaluating a first deterministic function based upon the received random string, a locally generated string and a first private key stored on the constrained device; and transmitting at least one portion of the responsive output and the locally generated string from the constrained device to a server. The systems and methods may also include determining, by the server, a validation output by evaluating a second deterministic function based upon the random string, the locally generated string, and a second private key of a plurality of private keys stored on the server; and authenticating the constrained device based upon the server matching the transmitted at least one portion of the responsive output to at least a portion of the validation output.
