Abstract:
A method and system for updating firmware of a device. A method includes receiving a decryption engine for decrypting encrypted firmware, loading the decryption engine into a first memory of a device, and receiving the encrypted firmware. The method may include obtaining a pre-stored encryption key from a second memory of the device, wherein the second memory is a different type of memory than the first memory, and decrypting the encrypted firmware using the encryption key and the decryption engine, wherein the decryption of the encrypted firmware occurs in the first memory.
