- Conference Paper 
Previous work on guessing is combined with the Shannon (1949) theory of cipher systems. A complexity measure is defined for breaking a cipher system by guessing at the key or the message. A single-letter characterization of the guessing effort for a discrete memoryless source (DMS) is given. © 1998 IEEE.
