The digital signature system comprises an electronic device and a data storage device. The electronic device generates a specific data by executing a specific operation, and calculates the specific data via a hash algorithm to generate a hash data. The data storage device comprises a controller, a plurality of flash memories, and a data transmission interface. The electronic device transmits the hash data to the data storage device via the transmission interface. The controller comprises a firmware. The firmware reads an unclonable function, and generates a private key according to the unclonable function, and encrypts the hash data by the private key to obtain a digital signature. The data storage device transmits the digital signature to the electronic device via the transmission interface."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Data storage device, system, and method for digital signature","description":"The invention discloses a digital signature system.
