摘要： The invention relates to a smartcard reader, and more particularly, to systems, devices and methods of creating a card input/output interface that allows the smartcard reader to couple to a smartcard within a secure cavity. The secure cavity is mounted on an internal side of a system housing, i.e., a smartcard socket, included in the smartcard reader. An interface chip is further attached inside the secure cavity. When the smartcard is inserted to a designated position or depth inside the system housing, the secure cavity encloses the interface chip and its contact area with the smartcard. Mechanical contacts on the interface chip are thus aligned to and physically contact electrical connectors on the inserted smartcard, so as to electrically couple the interface chip and the smartcard. As a result, sensitive data within the smartcard may be protected from exposure to any tamper attempt and processed with an enhanced security level.
摘要翻译：本发明涉及一种智能卡阅读器，更具体地说，涉及一种创建卡输入/输出接口的系统，设备和方法，该接口允许智能卡读卡器耦合到安全空间内的智能卡。安全腔安装在智能卡读卡器中的系统外壳的内侧，即智能卡插槽。接口芯片进一步安装在安全腔内。当智能卡插入到系统外壳内的指定位置或深度时，安全腔包围接口芯片及其与智能卡的接触区域。接口芯片上的机械触点因此与插入的智能卡上的电连接器对准并物理接触，以便电接地接口芯片和智能卡。因此，智能卡内的敏感数据可能受到保护，不受任何篡改尝试的影响，并以增强的安全级别进行处理。

摘要： The invention relates to a secure device, and more particularly, to systems, devices and methods of reducing power consumption of the secure device by limiting the amount of secure volatile memory that needs to be supplied by a battery. In a transport power mode, a sensitive data originally stored in a volatile memory is backed up in an encrypted format to a non-volatile memory, such that none or only a small area of the secure volatile memory has to be retained and powered by the battery for preserving cryptographic keys that are used to backup and recover the sensitive data. This secure device is applied in high security applications such as secure financial terminals.
