Figure 2 : Hardware Configuration of the TOE

Controller Board

The Controller Board is a device that contains Processors, RAM, NVRAM, Ic Key, and FlashROM.

The following describes the components of the Controller Board:

- Processor

A semiconductor chip that performs basic arithmetic processing for MFP operations.

- RAM

A volatile memory medium which is used as a working area for image processing such as

compressing/decompressing the image data. It can also be used to temporarily read and write internal

information.

- NVRAM

A non-volatile memory medium in which TSF data for configuring MFP operations is stored.

- Ic Key

A security chip that has the functions of random number generation, cryptographic key generation and

digital signature. It has the memory medium inside, and the signature root key is installed before the

TOE is shipped.

- FlashROM

A non-volatile memory medium in which the following software components are installed:
