    • A storage device comprising a memory, a controller, and a host interface operative to connect with a host. The memory contains data locations that are controllable by a protection application which is executable on a host. When the host interface is operatively coupled to a host, data locations in the memory are accessible to an operating system of the host under permission from the protection application. The controller communicates with the protection application running on the host for allowing the protection application access to data locations in the memory. Upon a host request for access to a data location, the controller determines if permission to access the requested data location is acquired from the protection application. The permission is based on a determination by the protection application that the data location does not contain malicious data.
    • 一种存储设备,包括可操作以与主机连接的存储器,控制器和主机接口。 存储器包含可由可在主机上执行的保护应用程序控制的数据位置。 当主机接口可操作地耦合到主机时,存储器中的数据位置在主机允许的情况下可被主机的操作系统访问。 控制器与在主机上运行的保护应用程序通信,以允许保护应用程序访问存储器中的数据位置。 在主机访问数据位置的请求时,控制器确定是否从保护应用程序获取访问请求的数据位置的权限。 许可基于保护应用程序确定数据位置不包含恶意数据。

    • A first storage device provides a host device with access to a private memory area by communicating a password between the first storage device and a second storage device via the host device using a double-encryption scheme. In one embodiment, a host device receives a twice-encrypted password from a first storage device, sends the twice- encrypted password to a second storage device, receives a once-encrypted password from the second storage device, decrypts the once-encrypted password to obtain the password, and sends the password to the first storage device. In another embodiment, a first storage device sends a twice-encrypted password to a host device, receives the password from the host device after the twice-encrypted password is decrypted by a second storage device and the host device, and provides the host device with access to the private memory area only if the password matches one that is stored in the first storage device.
    • 第一存储设备通过使用双加密方案经由主机设备在第一存储设备和第二存储设备之间传送密码来向主机设备提供对专用存储器区域的访问。 在一个实施例中,主机设备从第一存储设备接收两次加密的密码,将二次加密的密码发送到第二存储设备,从第二存储设备接收一次加密的密码,将一次加密的密码解密为 获取密码,并将密码发送到第一个存储设备。 在另一个实施例中,第一存储设备向主机设备发送两次加密的密码,在由第二存储设备和主设备解密两次加密的密码之后从主机设备接收密码,并向主机设备提供 仅当密码与存储在第一存储设备中的密码匹配时,才能访问私有内存区域。
