  • Patent number: 10439755
    Abstract: Systems and methods of friendly jamming for securing wireless communications at the physical layer are presented. Under the assumption of exact knowledge of the eavesdropping channel, a resource-efficient distributed approach is used to improve the secrecy sum-rate of a multi-link network with one or more eavesdroppers while satisfying an information-rate constraint for all links. A method based on mixed strategic games can offer robust solutions to the distributed secrecy sum-rate maximization. In addition, a block fading broadcast channel with a multi-antenna transmitter, sending two or more independent confidential data streams to two or more respective users in the presence of a passive eavesdropper is considered. Lastly, a per-link strategy is considered and an optimization problem is formulated, which aims at jointly optimizing the power allocation and placement of the friendly jamming devices for a given link under secrecy constraints.

  • Publication number: 20060015518
    Abstract: A system for managing drug labeling information includes a repository comprising a network accessible database, the repository having an upload portion and a download portion, the repository being accessible to a plurality of users via client computers coupled to a wide area network. The repository includes drug labeling information on a plurality of drugs stored therein. The upload portion of the repository is accessible by a first set of users while the download portion of the repository is accessible by a second set of users. In one preferred aspect of the invention, drug manufactures are able to upload new or revised PDF files containing drug labeling information. The new or revised PDF files are then available for download by pharmacists or other authorized users.
