A physical quantity generation part 190 generates a physical quantity intrinsic to the electronic device and having a value which is different from one electronic device to another and different each time the physical quantity is generated. A key generation part 140 generates the same key for each key-using process, based on the physical quantity generated by the physical quantity generation part 190, each time the key-using process is to be executed, immediately before the key-using process is started. A key-using process execution part 1010 executes the key-using process such as generation of a keyed hash value, by using the key generated by the key generation part 140. A control program execution part 180 deletes the key generated by the key generation part 140, each time the key-using process is ended."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic device, key generation program, recording medium, and key generation method","description":"An electronic device 100 executes a key-using process that uses a key.
