Abstract: A system (300, 400, 500), device (1200), and method (600) for managing multicast group memberships in a multicast network uses IGMP spoofing to consolidate the multicast group memberships of a number of multicast hosts into a single IGMP Host. The IGMP spoofing agent maintains a group list indicating the multicast group membership status for the number of multicast hosts. The IGMP spoofing agent establishes a multicast group membership with a remote multicast device when at least one of the number of mulicast hosts requests membership in the multicast group. The IGMP spoofing agent cancels the multicast group with the remote multicast device when all of the multicast hosts have left the multicast group. The IGMP spoofing agent responds to status inquiries from the remote multicast device as a proxy on behalf of the number of multicast hosts.

Title: Generalized user identification and authentication system
Inventor: MANZA MARC B
IPC: G06F21/62
Filed: 1998-05-12
Abstract: The invention features a method for providing a user access to a secure application. The invention stores in an encrypted form the authentication information necessary to satisfy the authentication requirements of the secure application. When the user requests access to the secure application, the user is presented at his or her display with a request for authentication. The user must manipulate at least a portion of the symbol to respond properly to the authentication request. The user's manipulation(s) of the symbol(s) generate a CodeKey used to decrypt the encrypted stored authentication information into a result. After the result is created, it is provided to the secure application. If the result support's the secure application's authentication requirements (i.e., if the CodeKey has properly decrypted the encrypted stored authentication information), the user will be granted access to the secure application. The invention therefore provides a simple, secure and effective method for a user to gain access to a multitude of secure applications without having to recall a series of complicated passwords.
