摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译： 安全LSI装置1包括用于加密程序的加密部分2和用于从/向外部存储器100输入/输出程序或数据的外部I / F 50.在加密部分2中，私钥的操作 算术处理部分20对于由密钥生成/更新定序器30确定执行的序列被禁止是不允许的。 在外部I / F 50中，程序处理部分51和数据处理部分55彼此独立地构成。
