    • A secure media device preferably includes a Universal Serial Bus (USB) Mass Storage Class (MSC) interface and a USB Human Interface Device (HID) interface. A storage media area is also preferably provided. The storage media is preferably divided into a secure and nonsecure area by arranging the storage media into multiple Logical Units (LUNs). The nonsecure area is preferably accessed in a conventional manner using a host USB MSC driver through the USB MSC interface on the storage device. A password dialog application can be located in the nonsecure area of the storage device. A preferred method of configuring a secured storage device includes dividing storage media of the storage device into a secure and a nonsecure area. A password for accessing the secure area is preferably set using a host USB HID driver and a USB HID interface on the storage device. A preferred method of accessing a secure area of a USB secure storage device includes verifying a password using a host USB HID driver and a USB HID interface of the storage device. Once the password is verified, the secure area is preferably unlocked. After the secure area is unlocked, the storage device preferably responds to a host USB MSC driver poll with an indication that the secure area is accessible. Until the secure area is unlocked, the storage device preferably responds to a host USB MSC driver poll with an indication that the secure area is inaccessible. The secure area of the USB secured storage device is preferably locked via firmware in response to a removal or other locking event. According to various aspects of this invention, therefore, there is preferably no need for a custom driver or software package to be installed on a host computer to facilitate access to the data contained in the secure media area.
    • 安全媒体设备优选地包括通用串行总线(USB)大容量存储类(MSC)接口和USB人机界面设备(HID)接口。 还优选地提供存储介质区域。 优选地,存储介质通过将存储介质布置成多个逻辑单元(LUN)来分成安全和非安全区域。 优选地,通过使用主机USB MSC驱动器通过存储设备上的USB MSC接口以常规方式访问非安全区域。 密码对话框应用程序可以位于存储设备的非安全区域。 配置安全存储设备的优选方法包括将存储设备的存储介质划分为安全和非安全区域。 用于访问安全区域的密码优选地使用存储设备上的主机USB HID驱动器和USB HID接口来设置。 访问USB安全存储设备的安全区域的优选方法包括使用存储设备的主机USB HID驱动器和USB HID接口来验证密码。 一旦密码被验证,安全区域最好被解锁。 在安全区域被解锁之后,存储设备优选地响应主机USB MSC驱动程序轮询,其中指示该安全区域是可访问的。 在安全区域被解锁之前,存储设备优选地响应主机USB MSC驱动程序轮询,并指示安全区域是不可访问的。 USB安全存储设备的安全区域优选地通过固件来响应于去除或其它锁定事件被锁定。 因此,根据本发明的各个方面,优选地,不需要在主计算机上安装定制的驱动程序或软件包以便于访问包含在安全介质区域中的数据。
