An development environment of a high security level is provided for a key-installed system. Development of a program for a system having an LSI device which includes a secure memory is performed by providing another LSI device having the same structure and setting the provided LSI device to a development mode which is different from a product operation mode. Alternatively, the provided LSI device is set to an administrator mode to perform development and encryption of a key-generation program. The LSI device is set to a key-generation mode to execute the encrypted key-generation program, thereby generating various keys.

A system including a secure LSI 1 establishes a communication path to/from a server 3 (UD1), and receives a common key-encrypted program generated by encryption with a common key and transmitted from the server 3 (UD6 and UD7). The received common key-encrypted program is decrypted to generate a raw program, and the raw program is re-encrypted with an inherent key to newly generate an inherent key-encrypted program, which is stored in an external memory.

This invention discloses an etching processing apparatus wherein a member in the form of a sponge is soaked in an etching processing liquid vessel, for rubbing a surface of a lithographic master, which is conveyed by an endless belt, which rotates in a predetermined direction, through the etching processing liquid, so that the non-imaged part of the lithographic master may be made hydrophilic by keeping an adequate pressure between the sponge-form member and the endless belt.

A secure LSI device 1 includes an encryption section 2 for encrypting a program, and an external I/F 50 for inputting/outputting a program or data from/to an external memory 100. In the encryption section 2, the operation of a private key arithmetic processing section 20 is prohibited with respect to a sequence whose execution is determined by a key-generation/update sequencer 30 to be impermissible. In the external I/F 50, a program processing section 51 and a data processing section 55 are structured independently from each other.
摘要:
A network hardware device of the invention includes a reception section receiving data from a network, and outputting a reception completion signal, a timer section measuring a preset time, and a delay section generating an interrupt signal so as to notify a host CPU of completion of the reception. When the timer section does not measure a time, the delay section generates an interrupt signal upon reception of the reception completion signal. On the other hand, when the timer section measures a time, upon reception of the reception completion signal, the delay section generates an interrupt signal after the timer section measures a preset time.
