Abstract: Secure distribution of data objects using a unique quantum-safe cryptographic key provided to a user requesting the data object that has been authenticated using a zero-knowledge authentication. A user may access the system by way of the zero-knowledge authentication to request access to a data object of a data library. The system may generate and associate a unique quantum-safe cryptographic key for the instance of the data library to be provided to the authenticated user. The data object is encrypted using the unique quantum-safe cryptographic key. The encrypted data object and the unique quantum-safe cryptographic key are provided to the authenticated user. Other instances of the data object may also be encrypted with other unique quantum-safe cryptographic keys. In turn, access to a unique quantum-safe cryptographic key may not be useful in decrypting other instances of the data object, and other data objects may not be decrypted using a given unique key for a given data object instance.

Abstract: Apparatus and method for local authentication of a collection of processing devices, such as but not limited to storage devices (e.g., SSDs, etc.). In some embodiments, each of the processing devices stores an internal token value as a unique ID value associated with the corresponding processing device. A host controller circuit performs a local authentication of the collection by accessing a distributed ledger as a data structure in a memory that lists the internal token values of the respective processing devices. The distributed ledger may take the form of a blockchain. The processing devices may each further store an external token value as the internal token value of a selected one of the other processing devices in the collection. A newly added device may be initially authenticated using a remote server. Once authenticated, the device is added to the collection and thereafter authenticated locally.
