Abstract: Disclosed is an electronic device configured to perform a secure boot. The electronic device according to an embodiment disclosed herein may include: a first memory area for storing a firmware signed with a private key; a second memory area for storing a boot loader configured to verify integrity of the firmware and executing the firmware of which integrity has been verified; and a third memory area for storing a first public key paired with the private key, wherein the second memory area may store a second public key paired with the private key. The boot loader may verify the integrity of the firmware with the first public key when there is the first public key in the third memory area and verify the integrity of the firmware with the second public key when there is no first public key is in the third memory area.

Abstract: A firmware massive update method using a flash memory includes: a firmware data registration step of receiving, from a manufacturer server, at least one of information of a user device that is a firmware update target, and firmware information and registering the received information as firmware data; a firmware data management step of receiving a request from a firmware update server in which the registered firmware data is stored, and storing and managing the registered firmware data in a specific area of a flash memory included in the user device via a network; and a firmware update execution step of executing a firmware update on the firmware data managed in the specific area of the flash memory included in the user device through the firmware update server.

Abstract: Provided is a system-on-chip that may perform a message encryption operation based on a transport layer security (TLS) scheme. The system-on-chip may include an authentication unit configured for exchanging a key used for the message encryption operation and performing authentication for a subject to perform communication, an advanced encryption standard (AES) engine core configured for performing a function of encrypting a message using a key or decrypting the encrypted message and a function of encrypting the key or decrypting the encrypted key, and a controller configured for controlling the AES engine core and the authentication unit based on a real time operating system (RTOS) and firmware for performing the message encryption operation.
