The present disclosure provides systems and methods for enhanced wireless communication security. The preambles used for the identification of an upcoming wireless communication may be periodically changed (e.g., dynamic), on a time basis, based on a secret key function shared between the communicating parties. In this way, only the intended parties are able to recognize the start of an ongoing communication, synchronize with the transmitters, and access the information contained therein. An attacker, being unaware of the specific preamble sequence used for the synchronization, will not recognize the pattern of the communication, and thus will be unable to recognize when communications are ongoing. Additional authentication measures may also be implemented with the transmissions.

Dynamic preambles for establishing secure communication channels

The presently disclosed method and system exploits a received signal strength of a jamming signal emitted by a jammer to allow navigation of an object through an area containing the jamming signal. In one embodiment, the method comprises receiving a plurality of navigation data and a jamming signal when entering a jamming zone. The method then comprises repeatedly measuring the strength of the jamming signal while moving within the jamming zone. The method then comprises determining the location of the jammer based on the movement within the jamming zone and the strength of the jamming signal at multiple coordinates. The method further comprises performing movement to destination coordinates within the jamming zone at least partially based on the jammer location and the strength of the jamming signal.
