    • An authentication method between a first IC card and a second IC card interconnected through a terminal includes transmitting an identification number from the second IC card to the first IC card for deriving and storing a key in the first IC card. An authentication number is generated and stored in the first IC card, and is transmitted to the second IC card. The authentication number is encrypted inside the second IC card, and is transmitted to the first IC card. The encrypted authentication number is decrypted through the derived key, and is compared with the authentication number. The second IC card is authorized if the encrypted authentication number in the first IC card is equal to the authentication number. At least one of the transmissions includes an identification and/or authentication number to authorize the first IC card from the second IC card. The identification and/or authentication numbers include a reverse authentication number.
    • 通过终端互连的第一IC卡和第二IC卡之间的认证方法包括从第二IC卡向第一IC卡发送识别号码,用于导出和存储第一IC卡中​​的密钥。 生成认证号码并将其存储在第一IC卡中​​,并被发送到第二IC卡。 认证号码在第二IC卡内进行加密,并发送到第一IC卡。 加密认证号码通过派生密钥解密,并与认证号进行比较。 如果第一IC卡中​​的加密认证号码等于认证号,则授权第二IC卡。 传输中的至少一个包括从第二IC卡授权第一IC卡的标识和/或认证号码。 标识和/或认证号码包括反向认证号码。
