1. A method for managing information of an electronic device including a control circuit, comprising:
utilizing a static entropy source to provide static entropy data;
utilizing a cryptographic circuit to generate a public key and a private key according to the static entropy data, wherein the public key is to be registered into a blockchain by an identifier (ID) management device;
utilizing the cryptographic circuit to generate the public key and the private key to an internal register, wherein the internal register is unreadable for outside of the electronic device;
transmitting the public key to a non-volatile memory (NVM) from the internal register, wherein the private key is prevented from being transmitted to the NVM; and
utilizing a signature generating circuit to generate a digital signature at least according to the private key, wherein the information of the electronic device is to be uploaded to the blockchain in conjunction with the digital signature.
