Abstract: A computer system, a method of a computer system and a computer-readable medium securely transmit and verify a multiparty agreement. The method, the computer system, and the computer readable medium include developing and transmitting views of the multi-party agreement by each party to a separate verification party. The verification party authenticates the participants and determines whether the views of the agreement are mutually consistent, and notifies the partys of the results of the comparison.

Abstract: A method of migrating across link technologies on an IP-based subnet while maintaining on-going communication comprises selecting a link, and notifying interested hosts of the address of the selected link. A mobile computing devices migrates across link technologies on a subnet while maintaining on-going communication and comprises a link migration module selecting a link, and notifying interested hosts of the address of the selected link, and a dynamic MAC to IP binding module binding a MAC address to an IP address based upon the selected link. A computer-readable medium storing a program which when executed by a computer causes the computer to execute the functions of migrating across link technologies on a subnet while maintaining on-going communication, comprising selecting a link, and notifying interested hosts of the address of the selected link. The migration is executed within the mobile computing device and does not entail modification to the other components of the network.
