摘要:
A policy server program evaluates one or more policy statements based on the group or groups to which a user belongs as well as other conditions. Each policy statement expresses an implementation of the access policy of the network, and is associated with a profile. The profile contains one or more actions that are to be applied to the user. The policy server program determines the identity of the group or groups to which the user belongs by referencing one or more group attributes contained in a user object which is located in a directory on the network. The user object and its group parameters are established when the user is added to the directory, while a policy statement for a group can be created at any time.

A system is provided for establishing a secure link among multiple users on a single machine with a remote machine. The system includes a subsystem to filter traffic so that traffic from each user is separate. The subsystem generates and associates a Security Association (SA) with at least one filter corresponding to the user and the traffic, and employs the SA to establish the secure link. An Internet Key Exchange module and a policy module may be included to generate and associate the security association, wherein the policy module is configured via Internet Protocol Security (IPSEC).

A system for maintaining network information. The system resides in a network comprising a plurality of sub-networks in communication with one another over a communications backbone. Each sub-network has a router for use in performing communications with other sub-networks. A directory service is linked to the communications backbone and includes a database. The database stores router attribute information that is published by each of the routers. Using a query engine associated with the directory service, meaningful information can be gathered from the database as a function of specified router attribute information.

Disclosed are methods for a client, having established one set of security keys, to establish a new set without having to communicate with an authentication server. When the client joins a group, master session security keys are derived and made known to the client and to the group's access server. From the master session security keys, the access server and client each derive transient session security keys, used for authentication and encryption. To change the transient session security keys, the access server creates “liveness” information and sends it to the client. New master session security keys are derived from the liveness information and the current set of transient session security keys. From these new master session security keys are derived new transient session security keys. This process limits the amount of data sent using one set of transient session security keys and thus limits the effectiveness of any statistical attacker.

A trust web keying process provides secure peer networking of computing devices on an open network. A device is initially keyed at distribution to an end user or installer with a device-specific cryptographic key, and programmed to respond only to peer networking communication secured using the device's key. The device-specific key is manually entered into a keying device that transmits a re-keying command secured with the device-specific key to the device for re-keying the device with a group cryptographic key. The device then securely peer networks with other devices also keyed with the group cryptographic key, forming a trust web. Guest devices can be securely peer networked with the trust web devices via a trust web gateway.

A computer system attempts to authenticate with a server to gain authorization to access a first network. It is determined by the server that the computer system is not authorized to access the first network. The computer system is given authorization to access a second network for at least the purpose of downloading files (e.g., signup and configuration files) needed to access the first network. A user-interface for receiving user-entered signup information is automatically presented at the computer system. A first schema-based document including user-entered information is transferred to the server. If the server determines that the user-entered information is appropriate, a second-schema document, which includes an indication of authorization to access the first network (e.g., a user-identifier and password), is received. A third schema-based document is executed at the computer system to compatibly configure the computer system for accessing the first network.

The principles of the present invention relate to systems, methods, and computer program products for more efficiently and securely authenticating computing systems. In some embodiments, a limited use credential is used to provision more permanent credentials. A client receives a limited-use (e.g., a single-use) credential and submits the limited-use credential over a secure link to a server. The server provisions an additional credential (for subsequent authentication) and sends the additional credential to the client over the secure link. In other embodiments, computing systems automatically negotiate authentication methods using an extensible protocol. A mutually deployed authentication method is selected and secure authentication is facilitated with a tunnel key that is used encrypt (and subsequently decrypt) authentication content transferred between a client and a server. The tunnel key is derived from a shared secret (e.g., a session key) and nonces.
