Assignee: PUFSECURITY CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 10:
11. 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; and wherein the private key is stored in an internal register that is unreadable for outside of the electronic device;
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;
receiving a public key of a remote host from the remote host, to allow the control circuit to confirm whether the public key of the remote host is registered in the blockchain; and
sending the public key of the control circuit to the remote host from the control circuit, to allow the remote host to confirm whether the public key of the control circuit is registered in the blockchain.
