A system on chip is provided. The system on chip includes a first memory to store a plurality of encryption keys, a second memory, a third memory to store an encryption key setting value, and a CPU to decrypt 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, to store the decrypted data in the second memory, and to perform a boot using data stored in the second memory. Accordingly, security of a boot operation can be improved.

System on chip to perform a secure boot, an image forming apparatus using the same, and method thereof

An image forming apparatus includes a communication interface unit which communicates with an external apparatus, a controller which, if a job performance command is received from the external apparatus when an operation mode of the image forming apparatus is a power saving mode, performs authentication of the external apparatus while maintaining the power saving mode, and a function unit which converts an operation mode of the image forming apparatus according to the authentication result and performs a function corresponding to the job performance command.

Image forming apparatus, driving method thereof, and computer-readable recording medium

An image forming apparatus includes a storage unit, an interface unit which is connected to a host apparatus and at least one of other image forming apparatuses, an image forming unit which prints image data received through the interface unit, and a controller which, if image data is received when the image forming apparatus is in a normal mode, controls the image forming unit to perform an image forming job using the image data, and if the image data is received when the image forming apparatus is in a power saving mode, controls the interface unit to transmit the image data to another image forming apparatus so that the another image forming apparatus performs an image forming job.
