    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: 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: 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: 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.
