摘要： A system transfers applications and datasets (files) from a server to a client device and assigns to each file a lease key that will expire at a specified time. A file cannot be accessed unless its lease key is validated. Upon expiration of a lease key, the client device will connect to the server to determine if the lease key may be renewed. If the lease key may be renewed, a new lease key is created and access to the associated application or dataset is restored. If the lease key may not be renewed, the file may be deleted or rendered inaccessible. If rendered inaccessible, the file may be restored in the future without having to re-transmit it from the server to the client device. The server may also revoke a lease key before it expires.

摘要翻译：系统将应用程序和数据集（文件）从服务器传输到客户端设备，并为每个文件分配将在指定时间过期的租用密钥。无法访问文件，除非验证其租用密钥。在租赁密钥到期后，客户端设备将连接到服务器，以确定租约密钥是否可以更新。如果可以更新租赁密钥，则会创建一个新的租赁密钥，并恢复对关联的应用程序或数据集的访问。如果租赁密钥不能被更新，则该文件可能被删除或不可访问。如果渲染不可访问，则可以在将来恢复文件，而不必将其从服务器重新发送到客户端设备。服务器也可以在租期过期前撤销租赁密钥。
