Information Theoretically Secure Encryption Key Generation over Wireless Networks by Exploiting Packet Errors

This article presents a novel method for establishing an information theoretically secure encryption key over wireless channels. It exploits the fact that data transmission over wireless links is accompanied by packet error, while noise terms, and thereby the error events observed by two separate receivers are independent of each other. A number of data packets, with random data, are transmitted from a first legitimate node, say Alice, to a second legitimate node, say Bob. Bob identifies all packets that are …
