Phase-only Digital Encryption using a Three-pass Protocol

Abstract

This paper considers an application of phase-only digital encryption to the three-pass protocol leading to a new 'nokey-exchange algorithm'. After providing a study on the theoretical background to the method, an algorithm is presented on a step-by-step basis together with three examples of cryptanalysis. A prototype MATLAB function is provided for validation of the approach and for further development by interested readers.

“…The conditions provide a unique solution to the deconvolution problem. This is done to facilitate a decryption algorithm [98]. The deconvolution problem is associated with an IRF and the noise function, n. The latter is a source of noise, as described in component (i) above.…”

“…This is also subject to the condition that both the sender and receiver have access to an identical encryption/decryption algorithm and decryption key, such that deconvolution becomes equivalent to the decryption process. This approach provides a unique key-exchange method to be implemented using a three-pass protocol as presented in [109] for a quantum key exchange.…”
