    • A smart card, system, and method for securely authorizing a user or user device using the smart card is provided. The smart card is configured to provide, upon initialization or a request for authentication, a public key to the user input device such that the PIN or password entered by the user is encrypted before transmission to the smart card via a smart card reader. The smart card then decrypts the PIN or password to authorize the user. Preferably, the smart card is configured to provide both a public key and a nonce to the user input device, which then encrypts a concatenation or other combination of the nonce and the user-input PIN or password before transmission to the smart card. The smart card reader thus never receives a copy of the PIN or password in the clear, allowing the smart card to be used with untrusted smart card readers.
    • 提供了一种使用智能卡安全授权用户或用户设备的智能卡,系统和方法。 智能卡被配置为在初始化或请求验证时向用户输入设备提供公共密钥,使得在经由智能卡读卡器传输到智能卡之前,由用户输入的PIN或密码被加密。 智能卡然后解密PIN或密码以授权用户。 优选地,智能卡被配置为向用户输入设备提供公开密钥和随机数,该用户输入设备然后在发送到智能卡之前加密随机数和用户输入的PIN或密码的级联或其他组合。 因此,智能卡读卡器从未收到PIN或密码的副本,允许智能卡与不可信的智能卡读卡器一起使用。
