Systems and methods for generating reversible hash circuits from irreversible hash functions are disclosed, along with reversible hash circuits generated using such systems and methods. Generally, embodiments may obtain a hash function and generate a reversible hash circuit by mapping that irreversible hash function to a reversible hash circuit that includes reversible elements such that the reversible hash circuit may be utilized to obtain the corresponding input values from output values of the hash function.

Embodiments of PUF systems utilizing photonic circuits to generate a PUF signature based on a state of polarization of photons are disclosed. Embodiments of such PUFs may comprise substantially the same circuitry that may be operated in the classical domain or the quantum domain.

Systems and methods for implementing structures for physical unclonable functions

Embodiments of systems and methods for efficient photonic based quantum circuitry in a heralded system are disclosed. Embodiments may employ filters with a photon pair source to route photons to quantum circuit blocks in a quantum system. These quantum circuit blocks can process the photons routed to those quantum circuit blocks in the quantum system.

Embodiments of PUF systems are disclosed. Embodiments of such PUFs may be operated in the classical domain or the quantum domain, and moreover, may comprise substantially the same circuitry, and operate substantially the same, when operating in the classical domain or the quantum domain. Additionally, embodiments of such PUF systems may be effectively utilized to generate uniquely identifying signatures for electronic devices based on electronic circuity, photonic circuitry or some combination of electronic and photonic circuitry and may be utilized to generate such signatures for such electronic devices regardless of whether such electronic device themselves operate in the classical or quantum domain.

Systems and methods for hybrid physical unclonable functions

Embodiments of systems and methods for a multi-source true random number generator (TRNG) are disclosed. A set of values is generated from each of the sources of randomness and an extractor is applied each of the set of values to produce a set of random values from each source. At least one extractor for at least one of the sources is a multi-radix extractor. The sets of values generated from each source of randomness can be composited to generate a random bitstring as the output of the TRNG.

Embodiments of quantum ring oscillator-based coherence preservation circuits including a cascaded set of stages are described. Embodiments of such quantum ring oscillator-based coherence preservation circuits allow the internal (superpositioned) quantum state information of stored qubits to be preserved over long periods of time and present options for the measurement and potential correction of both deterministic and non-deterministic errors without disturbing the quantum information stored in the structure itself.

Systems and methods for preservation of qubits

Embodiments of feedback-based quantum circuits are described. Embodiments of such quantum circuits may be externally controlled using only basis or eigenstate (classically-observable) signals without triggering de-coherence. Additionally, embodiments of such quantum circuits allow the internal (superpositioned) quantum state information to be preserved over long periods of time and present options for quantum error-correction due to the basis-state controls. Moreover, a coupling of two such feedback-based quantum circuits allows for quantum-channel-based information exchange to a variety of ends.

Systems and methods for quantum coherence preservation of qubits

Embodiments of systems and methods disclosed herein include an embedded secret provisioning system that is based on a shared-derivative mechanism. Embodiments of this mechanism use a trusted third-party topology, but only a single instance of a public-private key exchange is required for initialization. Embodiments of the system and methods are secure and any of the derived secret keys are completely renewable in untrusted environments without any reliance on asymmetric cryptography. The derived secrets exhibit zero knowledge attributes and the associated zero knowledge proofs are open and available for review. Embodiments of systems and methods can be implemented in a wide range of previously-deployed devices as well as integrated into a variety of new designs using minimal roots-of-trust.

Method and system for an efficient shared-derived secret provisioning mechanism

Embodiments as described herein provide systems and methods for sharing secrets between a device and another entity. The shared secret may be generated on the device as a derivative of a secret value contained on the device itself in a manner that will not expose the secret key on the device and may be sent to the entity. The shared secret may also be stored on the device such that it can be used in future secure operations on the device. In this manner, a device may be registered with an external service such that a variety of functionality may be securely accomplished, including, for example, the generation of authorization codes for the device by the external service based on the shared secret or the symmetric encryption of data between the external service and the device using the shared secret.

System and method for initializing a shared secret system

Embodiments of systems and methods disclosed herein include renewable secure boot systems for renewing and booting a target device. Systems and methods include techniques by which a secure boot may be implemented in a renewable fashion on a reprogrammable device. More specifically, in certain embodiments, systems and methods are described where target devices securely receive an encrypted boot image and one or more authorization codes from a third party. The one or more authorization codes are derivatives of a target device hardware secret, allowing the authorization codes to be changed at will, thus increasing flexibility and security of the system.

System and method for a renewable secure boot

Systems and methods in which multiple key servers operate cooperatively to securely provide authorization codes to requesting devices. In one embodiment, a server cloud receives a device authorization code request and selects an 'A server'. The 'A server' requests authorization from one or more &#x201c;B servers&#x201d; and authorizes the &#x201c;B servers&#x201d; to respond. The &#x201c;B servers&#x201d; provide authorization to the &#x201c;A server&#x201d;, and may provide threshold key inputs to enable decryption of device authorization codes. The &#x201c;A server&#x201d; cannot provide the requested device authorization code without authorization from the &#x201c;B server(s)&#x201d;, and the &#x201c;B server(s)&#x201d; cannot provide the requested server authorization code and threshold inputs without a valid request from the &#x201c;A server&#x201d;. After the &#x201c;A server&#x201d; receives authorization from the &#x201c;B server(s)&#x201d;, it can provide the initially requested device authorization code to the requesting device.

Systems and methods for establishing and using distributed key servers

Embodiments of systems and methods disclosed herein provide a simple and effective method for authentication and key exchange that is secure from man-in-the-middle attacks and is characterized by perfect forward secrecy. More specifically, in certain embodiments, the systems and methods are disclosed that enable secure communications between a local device and a remote device(s) via a protocol that uses a Central Licensing Authority that shares derived secrets with the endpoints, without sharing the secrets themselves. The derived secrets may be comprised of public information, taking the form of nonces, in order to protect the system against replay-style attacks. Each endpoint can generate its own nonce with sufficient entropy such that neither endpoint is dependent on the trustworthiness of the other.
