To provide a user authentication device and a user authentication method that can manage a first encryption key with a simple configuration.SOLUTION: A user authentication device 2 performs encryption communication between an electronic key 3 and a communication opposite party with a first encryption key Ka, and authenticates a user using information obtained by encryption communication and identification information input from the user. The user authentication device includes an encryption key storage unit 33 that stores encrypted information on a first encryption key Ka' encrypted by the identification information in a non-volatile memory 13 provided at the communication opposite party.SELECTED DRAWING: Figure 1

    【課題】第1暗号鍵の管理を簡素な構成によって実現することができるユーザ認証装置及びユーザ認証方法を提供する。【解決手段】ユーザ認証装置2は、電子キー3と通信相手とで第1暗号鍵Kaを用いた暗号通信を行い、暗号通信で得られた情報と、ユーザから入力された識別情報を用いてユーザの認証を行う。識別情報によって暗号化された第1暗号鍵Ka’の暗号化済み情報を、通信相手に設けられた不揮発性メモリ13に保存を実行する暗号鍵保存部33を備える。【選択図】図1
