摘要： A secure computing environment in which a computer automatically operates in a full-access data storage mode when it detects the presence of a secure removable storage device. In full-access mode all data written to removable storage device is encrypted with a cryptographic key and the user is given access to sensitive if authorized. Otherwise, the computer operates in a restricted-access mode in which the user is unable to write to the removable storage device and is unable to access sensitive data. The invention detects security information on the data storage device and generates a cryptographic key from the security information. The security information can be a function of the unique format characteristics of the underlying storage medium, a unique identifier retrieved from an electronic circuit embedded within the removable storage device or a serial number etched on the storage device during manufacturing. In addition, drive-specific information and even user-specific information can also be used to generate the cryptographic key, thereby creating a highly secure computing environment. When the computer operates in a full-access mode, all data written to the storage device is encrypted and the user is able access to sensitive data within the organization. When security information is not present on the removable storage device the computer automatically operates in a restricted-access mode in which the user does not have access to sensitive data and data cannot be written to the removable storage device.
摘要翻译：一种安全计算环境，其中当计算机检测到存在安全的可移动存储设备时，计算机以全访问数据存储模式自动操作。在完全访问模式下，写入可移动存储设备的所有数据都使用加密密钥进行加密，如果授权用户可以访问敏感的访问权限。否则，计算机以限制访问模式操作，其中用户不能写入可移动存储设备并且不能访问敏感数据。本发明检测数据存储装置的安全信息，并根据安全信息生成密码密钥。安全信息可以是底层存储介质的唯一格式特征的函数，从嵌入在可移除存储设备内的电子电路检索的唯一标识符或在制造期间蚀刻在存储设备上的序列号。此外，还可以使用驱动器特定信息甚至用户特定的信息来生成加密密钥，从而创建高度安全的计算环境。当计算机以完全访问模式运行时，写入存储设备的所有数据都被加密，用户可以访问组织内的敏感数据。当可移动存储设备上不存在安全信息时，计算机在限制访问模式下自动操作，其中用户不能访问敏感数据，并且数据不能写入可移动存储设备。
