摘要
A key storage device comprises a one-way receiving interface, a key calculation unit, and a one-way outputting interface. The key calculation unit includes a signature unit. The one-way receiving interface receives a transaction message of an external electronic device in a single direction. The signature unit encrypts the transaction message by a private key to generate a signature message. And, the one-way outputting interface transmits the signature message to the external electronic device in a single direction.
