Abstract

See full text

A method for secure storage of secret data begins with an originating device transforming the secret data to produce a plurality of secret data shares and encrypting the plurality of secret data shares using unique encryption values of trusted agent modules of a dispersed storage network (DSN) to produce a plurality of encrypted secret data shares for storage in storage nodes of the DSN. Retrieval of the secret data begins with the originating device sending a secret data retrieval request to the trusted agent modules and recovering, by the trusted agent modules, the plurality of encrypted secret data shares from the storage nodes. The method continues with the trusted agent modules decrypting the plurality of encrypted secret data shares using a decryption function corresponding to the unique encryption values and sending the plurality of secret data shares to the originating device.
