MEMORY DEVICE AND MEMORY SYSTEM

摘要

For authentication of the host device, the memory device is configured to output the encrypted second key information (FKB) to the host device, output the encrypted identification information (E-SecretID) to the host device, generate third third key information (Hkey) using information (HC) received from the host device and the first key information, generate a session key (Skey) using a random number (RN) received from the host device, and the third key information,
generate authentication information (Oneway-ID) by performing a one-way conversion process on the identification information, using the session key, and output the authentication information (Oneway-ID) to the host device.

1. A memory device, comprising:
a first memory area in which reading and writing from outside of the memory device is inhibited at least after shipment of the memory device; a second memory area in which reading from outside of the memory device is permitted, while writing is inhibited; and a third memory area in which reading and writing from outside of the memory device is permitted, the first memory area being an area for storing first key information (Nkey) and identification information (SecretID), the second memory area being an area for storing encrypted identification information (E-SecretID) generated by encrypting the identification information using second key information (Fkey), the third memory area being an area for storing encrypted second key information (FKB) generated by encrypting the second key information, for authentication of the host device, the memory device being configured to output the encrypted second key information (FKB) to the host device, output the encrypted identification information (E-SecretID) to the host device, generate third third key information (Hkey) using information (HC) received from the host device and the first key information, generate a session key (Skey) using a random number (RN) received from the host device, and the third key information, generate authentication information (Oneway-ID) by performing a one-way conversion process on the identification information, using the session key, and output the authentication information (Oneway-ID) to the host device.
