Abstract: Systems, methods, and computer-readable media for eliminating unwanted data packets by a restricted bandwidth network that interfaces with a second network are provided. In embodiments, a device receives unwanted data packets associated with identification of the device. Due to the transient nature of some forms of device identification, data packets intended for one user may be received by another user who has taken on the device identification of the first user. To remedy this situation, unwanted data packets are identified and blocked at a gateway based on the source and/or destination identification associated with the data packets.

Abstract: This present invention provides a method and system for detecting and mitigating RTP-based denial of service attacks. A prediction model is implemented to analyze data within RTP packets to predict a range of valid data for future packets. Subsequent RTP packets that contain data that fall within the predicted range of data are considered valid RTP packets while others may be considered invalid packets subject to additional analysis.

Abstract: A system and method for exchanging secure communications between devices. A broadcast message is periodically transmitted. The broadcast message contains a public key. A response to the broadcast message is received from a client device. The response is encrypted with use of the public key. Further, the response contains the client's public key. Messages encrypted with the client's public key are communicated to the client device.
