Physical-Layer Encryption on the Public Internet: a Stochastic Approach to the Kish-Sethuraman Cipher

Authors: Lachlan J. Gunn, James M. Chappell, Andrew Allison, Derek Abbott

While information-theoretic security is often associated with the one-time pad and quantum key distribution, noisy transport media leave room for classical techniques and even covert operation. Transit times across the public internet exhibit a degree of randomness, and cannot be determined noiselessly by an eavesdropper. We demonstrate the use of these measurements for information-theoretically secure communication over the public internet.
