Abstract

An encryption key fragment is divided into a number of encryption key fragments. Requests to store different ones of the encryption key fragments are transmitted to different computer memory storage systems. An individual request to store an encryption key fragment includes one of the encryption key fragments and bears an access control hallmark for regulating access to the encryption key fragment.
