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.

A method writing data received from a host device includes determining whether command data of a write command includes metadata, flushing the command data out of a volatile write cache according to a first caching policy responsive to a determination that the command data does includes metadata, and flushing the command data out of the volatile write cache according to a second different caching policy responsive to a determination that the command data does not include metadata.

Metadata-specific cache policy for device reliability
