SYSTEM ON CHIP FOR PERFORMING SECURE BOOT, IMAGE FORMING APPARATUS USING THE SAME, AND METHOD THEREOF |
| 摘要 |
A system on chip is provided. The system on chip includes: a first memory in which a plurality of encryption keys are stored, a second memory, a third memory in which an encryption key setting value is stored, and a CPU which decrypts encrypted data which is stored in an external non-volatile memory using an encryption key corresponding to the encryption key setting value from among the plurality of encryption keys, stores the decrypted data in the second memory, and performs boot using data stored in the second memory. Accordingly, security of boot can be improved. |
