    摘要： Methods and systems consistent with the present invention provide dynamic security policies that change the granularity of the security at the node level, process level, or socket level. Specifically, a channel number and virtual address are associated with various processes included in a process table. Since a security policy is required for all processes, secure and insecure processes located on the same channel may communicate with one another. Moreover, processes located on different channels may communicate with one another by a gateway that connects both channels. This scalable blanketing security approach provides an institutionalized method for securing any process, node or socket by providing a unique mechanism for policy enforcement at runtime or by changing the security policies.

    摘要翻译： 与本发明一致的方法和系统提供动态安全策略，其改变节点级别，过程级别或套接字级别的安全性的粒度。 具体地，通道号和虚拟地址与包括在处理表中的各种处理相关联。 由于所有进程都需要安全策略，因此位于同一通道上的安全和不安全进程可能会相互通信。 此外，位于不同信道上的进程可以通过连接两个信道的网关彼此通信。 这种可扩展的覆盖安全方法提供了一种制度化的方法，用于通过在运行时或通过更改安全策略提供用于策略实施的唯一机制来保护任何进程，节点或套接字。

    摘要： Methods and systems consistent with the present invention provide a Supernet, a private network constructed out of components from a public-network infrastructure. Supernet nodes can be located on virtually any device in the public network (e.g., the Internet), and both their communication and utilization of resources occur in a secure manner. As a result, the users of a Supernet benefit from their network infrastructure being maintained for them as part of the public-network infrastructure, while the level of security they receive is similar to that of a private network. The Supernet has an access control component and a key management component which are decoupled. The access control component implements an access control policy that determines which users are authorized to use the network, and the key management component implements the network's key management policies, which indicate when keys are generated and what encryption algorithm is used. Both access control and key management are separately configurable. Thus, the Supernet provides great flexibility by allowing different key management policies to be used with the same access control component.

    摘要翻译： 与本发明一致的方法和系统提供了一种Supernet，一种由公共网络基础设施的组件构成的私有网络。 超网络节点可以位于公共网络（例如，因特网）中的几乎任何设备上，并且资源的通信和利用都以安全的方式发生。 因此，Supernet的用户受益于其网络基础架构，作为公共网络基础架构的一部分，而其接收的安全级别与私有网络的安全级别相似。 Supernet具有访问控制组件和分离的密钥管理组件。 访问控制组件实现访问控制策略，其确定哪些用户被授权使用网络，并且密钥管理组件实现网络的密钥管理策略，其指示生成密钥以及使用什么加密算法。 访问控制和密钥管理都可以单独配置。 因此，通过允许不同的密钥管理策略与相同的访问控制组件一起使用，Supernet提供了极大的灵活性。

    摘要： Methods and systems consistent with the present invention provide a Supernet, a private network constructed out of components from a public-network infrastructure. Supernet nodes can be located on virtually any device in the public network (e.g., the Internet), and both their communication and utilization of resources occur in a secure manner. The Supernet also uses multicast communication to create Ethernet-like communication between its nodes. In using multicasting, each communication of each node on a channel in the private network is sent to a multicast address which sends it to all of the nodes on the channel. Sending a copy of every communication to all of the other nodes on the channel makes system tasks, like debugging, easy for the nodes on the channel. The multicasting provided by the private network is dynamic in that multicast addresses can be assigned for use by a channel and reclaimed so as to allow sharing of the multicast addresses.

    摘要翻译： 与本发明一致的方法和系统提供了一种Supernet，一种由公共网络基础设施的组件构成的私有网络。 超网络节点可以位于公共网络（例如，因特网）中的几乎任何设备上，并且资源的通信和利用都以安全的方式发生。 Supernet还使用组播通信在其节点之间创建类似以太网的通信。 在使用多播时，专网中信道上的每个节点的每个通信都被发送到多播地址，将其发送到该信道上的所有节点。 将每个通信的副本发送到通道上的所有其他节点，使得系统任务（如调试）对于通道上的节点很容易。 由私有网络提供的多播是动态的，因为多播地址可以被分配给信道使用并被回收以允许多播地址的共享。

    摘要： Methods and systems consistent with the present invention provide a Supernet, a private network constructed out of components from a public-network infrastructure. Supernet nodes can be located on virtually any device in the public network (e.g., the Internet), and both their communication and utilization of resources occur in a secure manner by providing for anonymous communications within the network through addressing. As a result, the users of a Supernet benefit from their network infrastructure being maintained for them as part of the public-network infrastructure, while the level of security they receive is similar to that of a private network. Additionally, the nodes of the Supernet are not geographically restricted in that they can be connected to the Supernet from virtually any portal to the Internet in the world.
