A fast and secure "wireless telegraphy" for agents to send and receive ciphered messages. "A one way voice link known as OWVL is used over standard shortwave frequencies. It relies on the transmission of a series of seemingly random numbers. The numerical 'soup' could be deciphered only if the agent on the receiving end had a one-time pad corresponding to one used by the CIA sender."
