    • The invention enables a peripheral device to communicate with a host computing device to enable one or more security operations to be performed by the peripheral device on data stored within the host computing device, data provided from the host computing device to the peripheral device (which can then be, for example, stored in the peripheral device or transmitted to yet another device), or data retrieved by the host computing device from the peripheral device (e.g., data that has been stored in the peripheral device, transmitted to the peripheral device from another device or input to the peripheral device by a person). In particular, the peripheral device can be adapted to enable, in a single integral peripheral device, performance of one or more security operations on data, and a defined interaction with a host computing device that has not previously been integrated with security operations in a single integral device. The defined interactions can provide a variety of types of functionality (e.g., data storage, data communication, data input and output, user identification). The peripheral device can also be implemented so that the security operations are performed in-line, i.e., the security operations are performed between the communication of data to or from the host computing device and the performance of the defined interaction. Moreover, the peripheral device can be implemented so that the security functionality of the peripheral device is transparent to the host computing device.
    • 本发明使得外围设备能够与主机计算设备进行通信,以使得外围设备能够对存储在主机计算设备内的数据执行一个或多个安全操作,从主机计算设备提供给外围设备的数据(其可以 然后例如存储在外围设备中或被发送到另一个设备)或由主机计算设备从外围设备检索的数据(例如,已经存储在外围设备中的数据,从外部设备发送到外围设备 另一设备或人员对外围设备的输入)。 特别地,外围设备可以适于在单个集成的外围设备中实现对数据的一个或多个安全操作的性能,以及与先前尚未与单个的安全操作集成的主计算设备的定义的交互 整体装置。 定义的交互可以提供各种类型的功能(例如,数据存储,数据通信,数据输入和输出,用户识别)。 外围设备也可以被实现为使得安全操作是在线执行的,即,在与主机计算设备的数据通信或来自主计算设备的数据的通信与定义的交互的执行之间执行安全操作。 此外,可以实现外围设备,使得外围设备的安全功能对于主机计算设备是透明的。
