    • 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。
