Abstract: 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.

Abstract: 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.

Abstract translation: 为安装密钥的系统提供了高安全级别的开发环境。 通过提供具有相同结构的另一LSI器件和将所提供的LSI器件设置为与产品操作模式不同的开发模式来执行具有包括安全存储器的LSI器件的系统的程序的开发。 或者，将所提供的LSI设备设置为管理员模式，以执行密钥生成程序的开发和加密。 LSI设备被设置为执行加密密钥生成程序的密钥生成模式，从而生成各种密钥。
