Patent CA-2283178-A1 (CA)
Title: Method for generating asymmetrical cryptographic keys by the user
Inventor: METTKEN WERNER
IPC: H04L9/08
Filed: 1998-12-09
Abstract: Signature and encryption keys are needed for a user to generate asymmetric cryptographic keys, and reliable links to a trust centre are needed for personalization and certification. Security problems are encountered if a user wishes to generate his own keys, particularly encryption keys.  Such problems are mitigated by a method in which the user first obtains a key pair that has already been generated, personalized, and certified, as well as components for generating encryption pairs, from the trust centre. At some time or another, the user himself then generates an encryption key pair, signs the public portion of this pair with the secret signature key with which he has been provided, and sends the result to the trust centre, where it is assigned to the user by means of the certified public portion of the signature key pair. The domain of application for the present invention is to be found in all forms of asymmetric cryptographic methods: essentially bank card/bank transactions, access control to networks/data banks, access control to building/areas, digital signatures, digital passes/patient cards.

Patent CA-2296187-A1 (CA)
Title: Synchronization in video conferencing
Inventor: BURNS EMMETT R
IPC: H04L12/18
Filed: 1994-10-03
Abstract: A multimedia collaboration system that integrates separate real-time and asynchronous networks--the former for real-time audio and video, and the latter for control signals and textual, graphical and other data--in a manner that is interoperable across different computer and network operating system platforms and which closely approximates the experience of face-to-face collaboration, while liberating the participants from the limitations of time and distance. These capabilities are achieved by exploiting a variety of hardware, software and networking technologies in a manner that preserves the quality and integrity of audio/video/data and other multimedia information, even after wide area transmission, and at a significantly reduced networking cost as compared to what would be required by presently known approaches. The system architecture is readily scalable to the largest enterprise network environments. It accommodates differing levels of collaborative capabilities available to individual users and permits high-quality audio and video capabilities to be readily superimposed onto existing personal computers and workstations and their interconnecting LANs and WANs. In a particular preferred embodiment, a plurality of geographically dispersed multimedia LANs are interconnected by a WAN. The demands made on the WAN are significantly reduced by employing multi-hopping techniques, including dynamically avoiding the unnecessary decompression of data at intermediate hops, and exploiting video mosaicing, cut-and-paste and audio mining technologies so that significantly fewer wide area transmission paths are required while maintaining the high quality of the transmitted audio/video.
Patent CA-2298752-A1 (CA)
Title: A process to provide a secure network environment for computers that desire protection from unauthorized access while connected to a non-secure network
Inventor: DURWARD JAMES
IPC: H04L29/06
Filed: 2000-02-14
Abstract: The invention is a process for providing a secure network environment for computers that are connected to networks that are inherently non-secure by design. As the world's networks accelerate their conversion to high bandwidth cable, ADSL/DSL, and fibre connections, security issues surrounding this type of full-time connection have become of great concern. Computers using dial-up connections or direct full-time connections are vulnerable to hacker attacks. While larger corporate networks with full-time connections to the Internet are often protected by an internal firewall, residential, home office, and small business connections rarely are. Firewalls installed at the user location require proper configuration and maintenance, tasks that users may not want, or may not have the ability, to perform. All computers connected to the Internet without a firewall, whether using a dial-up or a full-time connection, are open to substantial risk of compromise. Current attempts to solve the problem require either that all computers in a joint communication have compatible encryption software or that each of the computers have a dedicated "firewall" to resist attempts from unauthorized computers to enter the communication loop. In the case where the user has created an encrypted virtual private network, that users computer remains exposed to external hacking and, in either case, the user must know in advance which network addresses will be contacted during a session or must suffer the time delay and inconvenience of inputting allowed network addresses as the session proceeds. Current methods also require constant maintenance by the user. The invention provides a high level of transparent security for computers that do not have dedicated firewalls or encryption software compatible with the desired target of communication (the "destination computer"). The result is the provision of network security with increased simplicity and reduced cost.

Title: A method for selecting a combination of modulation and channel coding schemes in a digital communication system
Inventor: THIELECKE JORN
IPC: H04L27/00
Filed: 1998-08-28
Abstract: A communication system that supports multiple modulation and channel coding schemes selects an optimum RF link by measuring link quality parameters, such as C/I ratio. All of the available RF links are characterized based on the measured link quality parameters by calculating mean values and variances of the parameters. Based on the characterization of the RF link, user quality values, such as user data throughput and speech quality values, are estimated. The communication system selects the RF link that provides the best user quality value.
