Substitution Ciphers are also known as One-Time-Pad ciphers. You need to know the original set of substitutions. If the pad is as long or longer than the message [ a requirement for secure transmission] than the code in unbreakable without the pad.

Please note that 1 or more "meanings" may be derived from the cipher in this case without the pad, but that does not mean that the sender intended that information. Consider you receive "FWDS" as a cipher. This could just as easily mean GURU as it means FOOL.
