Abstract
A key-based interleaver for enhancement the security of wireless communication includes a physical layer communication channel key to provide security even when the software encryption key is compromised. A method of creating a secure communication link using a physical layer interleaving system includes implementing a key policy implementation that utilizes temporal dependency and interleaving bits using a flexible inter and intra-block data interleaver.
Claims18
A wireless communications security system that secures communication between at least two parties comprising:
- a transmitter that transmits a packet, the transmitter including an interleaver that receives ordered data to be transmitted, and converts, according to a mapping, the ordered data to interleaved data to be sent in the packet;
- and
- a receiver that receives the packet, the receiver including a de-interleaver that de-interleaves, according to the mapping, the interleaved data into ordered data;
- wherein the mapping is accessible at the receiver only on the condition that the receiver has a key, and wherein the mapping is updated between the transmitter and the receiver synchronously and asynchronously.
A method of creating a secure communication link using a physical layer interleaving system comprising:
- implementing a key policy implementation that utilizes temporal dependency, and interleaving bits using a flexible inter and intra-block data interleaver based on updating a mapping between a transmitter and a receiver within the communication link synchronously and asynchronously.
