Mealy machines provide a rudimentary mathematical model for cipher machines. Considering the input and output alphabet the Latin alphabet , for example, then a Mealy machine can be designed that given a string of letters (a sequence of inputs) can process it into a ciphered string (a sequence of outputs).
Gopalakrishnan wrote a book on Computation Engineering [12] and in his book he encourages the use of JFLAP for experimenting with machines. JFLAP is also suggested to use for exercises. Mordechai Ben-Ari wrote a book entitled Principles of the SPIN model checker [13] and JFLAP is referenced in the book. In particular the Visualizing ...
Susan H. Rodger is an American computer scientist known for work in computer science education including developing the software JFLAP [1] [2] for over twenty years. JFLAP is educational software for visualizing and interacting with formal languages and automata.
A Mealy machine can be used as a cryptographic machine. Given an alphabet A, it is said to be possible to process a word from this alphabet into a word from alphabet B if there exists a Mealy machine which does this. Using mathematical notation, M - Mealy machine, -> - to process: thus a tuple (M, ->).

UML state machines have the characteristics of both Mealy machines and Moore machines. They support actions that depend on both the state of the system and the triggering event, as in Mealy machines, as well as entry and exit actions, which are associated with states rather than transitions, as in Moore machines. [4]
As Moore and Mealy machines are both types of finite-state machines, they are equally expressive: either type can be used to parse a regular language.. The difference between Moore machines and Mealy machines is that in the latter, the output of a transition is determined by the combination of current state and current input (as the domain of ), as opposed to just the current state (as the ...
A finite-state transducer (FST) is a finite-state machine with two memory tapes, following the terminology for Turing machines: an input tape and an output tape.This contrasts with an ordinary finite-state automaton, which has a single tape.
