Abstract
In order to create and access a secure storage account in a non-volatile memory device, an account identification value is calculated. A memory identification value is read from a first non-volatile memory device. The memory identification value and the account identification value are transmitted to a second non-volatile memory device, and a calculated credential is received. A command is transmitted to create a secure storage account in the first non-volatile memory device, where the command contains the credential and the account identification value. To access the account, a sequence is transmitted, containing the account identification value and a value based on the credential. A secure storage system contains a first non-volatile memory device that stores a memory identification value and contains a secure partition accessible using a credential, a second non-volatile memory device that can compute the credential, and a host adapted to create and access the secure partition.
