Abstract
A method of synchronizing the encryption/decryption functions of an AlphaEta physical-layer encryption or key generation system. The method includes the insertion of a header to indicate the start of encryption after clock-synchronization has been established. The method also allows for a side-channel to signal other useful information, such as a loss-of-syncrhonization signal from Bob or to synchronize a dynamic key change.
