  • Publication number: 20230244451
    Abstract: 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.

  • Patent number: 11657313
    Abstract: 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.

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.

  • Publication number: 20220376934
    Abstract: 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.

  • Patent number: 11080614
    Abstract: 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.

  • Publication number: 20200153808
    Abstract: 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.

  • Patent number: 10057224
    Abstract: 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.

  • Patent number: 9842212
    Abstract: 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.

  • Patent number: 9817953
    Abstract: 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 “B servers” and authorizes the “B servers” to respond. The “B servers” provide authorization to the “A server”, and may provide threshold key inputs to enable decryption of device authorization codes. The “A server” cannot provide the requested device authorization code without authorization from the “B server(s)”, and the “B server(s)” cannot provide the requested server authorization code and threshold inputs without a valid request from the “A server”. After the “A server” receives authorization from the “B server(s)”, it can provide the initially requested device authorization code to the requesting device.

  • Patent number: 9734355
    Abstract: 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.

  • Patent number: 9710617
    Abstract: Systems and methods are described which utilize a recursive security protocol for the protection of digital data. These may include encrypting a bit stream with a first encryption algorithm and associating a first decryption algorithm with the encrypted bit stream. The resulting bit stream may then be encrypted with a second encryption algorithm to yield a second bit stream. This second bit stream is then associated with a second decryption algorithm. This second bit stream can then be decrypted by an intended recipient using associated keys.
