  • SYSTEM AND METHOD FOR TRUSTLESS KEY PROVISIONING
    Publication number: 20260189373
    Abstract: A method includes providing a shared secret data to a device and also to a security service; using the provided shared secret data to provide a root key; and using the root key as a basis for a sequence of stages, wherein each stage comprises an operation which converts a start key into a different generated key, and the same stages are carried out in parallel at the device and at the security service. The root key is used as the start key for a first stage of the sequence, and a generated key produced by each stage of the sequence, except for the final stage of the sequence, is used as a start key for a next stage of the sequence. The keys produced by the last sequence stage at the device and at the security service are used to authenticate the device to the security service.

  • System and method for trustless key provisioning
    Patent number: 12413398
    Abstract: A method of encryption key provisioning that includes providing, by a quantum computing safe method, a shared secret data to a device and to a security service; using the provided shared secret data to provide a root key; and using the root key for a sequence of stages, wherein each stage includes an operation which converts a start key into a different generated key, and the same stages are carried out in parallel at the device and at the security service; wherein the root key is used as the start key for a first stage, and a generated key produced by each stage, except for the final stage, is used as a start key for a next stage of the sequence; and wherein the generated keys produced by the last stage of the sequence at the device and at the security service are symmetric keys.
