CONTROL METHOD AND INFORMATION PROCESSING APPARATUS |
| 摘要 |
A control method is executed by an information processing apparatus that includes a first processor; a second processor that executes a program to be protected; first memory that is shared between the first and the second processors; and non-volatile second memory that stores the program to be protected. The control method includes reading the program that is to be protected and stored in the second memory, when the information processing apparatus is started up; encrypting the read program only once after start up of the information processing apparatus; writing the encrypted program into the first memory; and decrypting the encrypted program that is written in the first memory, and causing the second processor to execute the decrypted program. |
