A Method of Securing Data Transferred Between Unmanned Aircraft System and Ground Control Station Based on One-Time Pads

Abstract

The paper provides a method of secure data transmitted and received data onboard 1he unmanned aircraft vehicle. An encryption method based on one-time pads (the Vemam cipher) is presented. The method uses such advantages of the Vemam cipher as theoretically proven absolute cryptographic security, high encryption speed and implementation simplicity. It allows the memory allocated for one-time pad to be used not only as a storage for key sequences but also as a place for storing the encrypted data.
