To provide an authentication system, an authentication method, and a key information issuing device, capable of improving security.SOLUTION: A vehicle 1 comprises a shared system 9 that issues key information Dk to a portable terminal 8 to perform authentication between the portable terminal 8 and an authentication device 11 and, on the basis of its authentication result, permits activation of the vehicle 1. The shared system 9 comprises: a first calculation unit 31 that on the basis of secret information Ds input at the time of issuing the key information Dk to the portable terminal 8, generates the key information Dk on the portable terminal 8 side; and a second calculation unit 35 that on the basis of the secret information Ds input at the time of the authentication between the portable terminal 8 and the authentication device 11, generates the key information Dk on the authentication device 11 side. The shared system 9 also comprises an authentication unit 33 for performing authentication using the key information Dk on the portable terminal 8 side and the key information Dk on the authentication device 11 side.SELECTED DRAWING: Figure 1
【課題】セキュリティ性を向上可能にした認証システム、認証方法及びキー情報発行装置を提供する。【解決手段】車両1には、キー情報Dkを携帯端末8に発行して携帯端末8と認証装置11との認証を行い、その認証結果を基に車両1の作動を許可する共用システム9を備える。共用システム9は、携帯端末8にキー情報Dkを発行する際に入力された秘密情報Dsを基に、携帯端末8側のキー情報Dkを生成する第1演算部31と、携帯端末8及び認証装置11の間の認証の際に入力された秘密情報Dsを基に、認証装置11側のキー情報Dkを生成する第2演算部35とを備える。また、共用システム9は、携帯端末8側のキー情報Dkと認証装置11側のキー情報Dkとを用いて認証を行う認証部33を備える。【選択図】図1
