摘要： PROBLEM TO BE SOLVED: To perform authentication using different authentication information each time without exchanging information required for generating authentication information at every authentication.SOLUTION: A user terminal 1 acquires authentication device time information indicating the time of a clock installed in an authentication device 2, and generates time difference information indicating time difference between the time which is indicated by the acquired authentication device time information and the time which is acquired from a clock installed in the user terminal 1 when the authentication device time information is acquired. When the user terminal 1 requires service from a service providing device 3, the user terminal 1 corrects the time acquired from the clock installed in the user terminal 1 on the basis of the time difference information, generates encrypted authentication information including the corrected time, and transmits the authentication information to the service providing device 3. The authentication device 2 acquires the time corrected by the user terminal 1 by decrypting the authentication information received by the service providing device 3, and determines that authentication is successful if the difference between the corrected time and the time acquired from the clock installed in the authentication device 2 is within a predetermined range.
摘要翻译：要解决的问题：每次认证时，不用交换生成认证信息所需的信息，进行不同认证信息的认证。解决方案：用户终端1获取表示安装在认证装置2中的时钟的认证装置时间信息，并且生成当获取认证装置时间信息时，指示由获取的认证装置时间信息指示的时间与从安装在用户终端1中的时钟获取的时间之间的时间差的时间差信息。当用户终端1从服务提供装置3需要服务时，用户终端1根据时差信息来校正从安装在用户终端1中的时钟获得的时间，生成包括校正时间的加密认证信息，以及将认证信息发送给服务提供装置3.认证装置2通过解密由服务提供装置3接收到的认证信息来取得用户终端1修正的时间，并且如果校正时间之间的差异并且从安装在认证装置2中的时钟获取的时间在预定范围内。

摘要： PROBLEM TO BE SOLVED: To provide an application authentication system and an application authentication method capable of verifying whether an application operating on an information terminal is a valid application installed on an appropriate information terminal.SOLUTION: An authentication server transmits a message to an information terminal. The information terminal encrypts the transmitted message using key information and inputs the encrypted message to a tamper-resistant device. The tamper-resistant device of the information terminal decrypts the encrypted message, and generates and outputs a first authenticator on the basis of the decrypted message and a signature key. The information terminal generates a second authenticator on the basis of the first authenticator output by the tamper-resistant device according to the message input to the tamper-resistance device and the key information, and transmits the generated authenticator to the authentication server. The authentication server receives the second authenticator transmitted from the information terminal according to the message transmitted to the information terminal, verifies the received second authenticator using the key information, and then verifies the first authenticator included in the second authenticator using the verification key corresponding to the signature key.
