Memory and storage devices to be authenicated using a host device, authenication system and host device

摘要

According to one embodiment, a device includes a second data generator configured to generate a session key (SKey) by encrypting a random number (RN) with the second key (HKey) in AES operation; a one-way function processor configured to generate an authentication information (Oneway-ID) by processing the secret identification information (SecretID) with the session key (SKey) in one-way function operation; and a data output interface configured to output the encrypted secret identification information (E-SecretID) and the authentication information (Oneway-ID) to outside of the device.

1. A system comprising:
a host device; and a storage device to be authenticated by the host device; wherein, the storage device comprises: a controller; and a memory controlled by the controller; comprising:
a first memory area being used to store a first key and unique secret identification information, the first memory area being restricted from being read and written from outside by the host device and the controller;a second memory area being used to store encrypted secret identification information generated by encrypting the secret identification information; anda third memory area being readable and writable; and wherein,
the memory is configured to generate a second key by using the first key and first host number information;the memory is configured to generate a session key by using the second key and second host number information;the memory is configured to generate authentication information by using the secret identification information and the session key;the memory is configured to generate the second key after the host device reads the encrypted secret identification information from the second memory area of the memory;the memory is configured to generate the session key after the host device sends an authentication request to the memory;the memory is configured to generate the authentication information after generating the session key;the memory is configured to output the authentication information to the host device after generating the session key;the host device is configured to send the first host number information and the second host number information to the memory; andthe host device is configured to verify the authentication information.
