Abstract

A method for execution by one or more processing modules of one or more computing devices of a dispersed storage network (DSN), the method begins by performing a key derivation function on a password and issuing a set of blinded passwords to a set of storage units. The method continues by receiving at least a decode threshold number of confidential information responses, regenerating a set of keys using the associated passkeys of the confidential information, decrypting a set of encrypted slices of the confidential information using the set of keys to reproduce a set of encoded data slices, and dispersed storage error decoding a decode threshold number of the set of reproduced encoded data slices to produce recovered data.
