Zusammenfassung:	An electronic device includes a first memory circuit, a second memory circuit, and a processor circuit. The first memory circuit is configured to store a key. The second memory circuit is configured to store an original software. The processor circuit is configured to receive data for updating, in which the data for updating includes a software for updating and a digital signature; perform a digest algorithm to process the software for updating and generate a first digest; utilize the key to decrypt the digital signature and generate a second digest; and compare the first digest with the second digest, in order to determine whether to update the original software to become the software for updating.
