    • Multi-level file digests for electronic files are disclosed. A top level digest represents a single digest for the associated electronic file. Lower level digests represent digests for portions of the associated electronic file. The top level digest is derived from the lower level digests. The top level digest is useful for facilitating rapid comparison to determine whether electronic files are the same. In one embodiment, electronic files are encrypted with a block encryption scheme, and digests are efficiently calculated and stored on a block-by-block basis. Advantageously, when modifications to an encrypted electronic file occurs, only those modified blocks need to be processed to undergo decryption and re-encryption to determine the appropriate digest.
    • 公开了电子文件的多级文件摘要。 顶级摘要表示相关联的电子文件的单个摘要。 较低级别的摘要代表了相关电子文件的部分的摘要。 顶级摘要源于较低级别的摘要。 顶级摘要可用于促进快速比较以确定电子文件是否相同。 在一个实施例中,使用块加密方案对电子文件进行加密,并且逐个基础地有效地计算和存储摘要。 有利地,当对加密的电子文件进行修改时,仅需要处理那些经修改的块以进行解密和重新加密以确定适当的摘要。

    • Improved approaches for providing notifications in a distributed file security system are disclosed. The file security system includes a file security server that manages file security for a plurality of clients. When security criteria (e.g., security policies or rules) change at the file security system, typically the clients need to be notified so that they operate in accordance with the correct security criteria. The security criteria impacts whether a particular client (or its user) are able to access certain files being protected by the file security system. A client can be notified in different ways depending on network characteristics. In one embodiment, an appropriate way to perform notifications between the file security server and clients can be automatically determined, thus advantageously minimizing user impact and allowing the system to transparently adapt to different networks.
    • 公开了在分布式文件安全系统中提供通知的改进方法。 文件安全系统包括管理多个客户端的文件安全性的文件安全服务器。 当安全标准(例如,安全策略或规则)在文件安全系统中改变时,通常需要通知客户端,使得它们根据正确的安全标准进行操作。 安全标准影响特定客户端(或其用户)是否能够访问受文件安全系统保护的某些文件。 可以根据网络特性以不同的方式通知客户端。 在一个实施例中,可以自动确定在文件安全服务器和客户端之间执行通知的适当方式,从而有利地最小化用户影响并允许系统透明地适应不同的网络。
