A homophonic cipher for computational cryptography

Abstract: Computational cryptography deals with the storage and processing of sensitive information in computer systems by enciphering. Sensitive information is information that for one reason or another must be protected from being disclosed to individuals without proper authorization. The need for systems to be secure from unauthorized access to sensitive information has been well documented. Cyrptographic techniques appear to be one of the most simple and secure methods of providing this much needed protection.

Design considerations for cryptography

Abstract: Enciphering data can protect the transmission of information against unauthorized observers. One way of doing this when data is transmitted in binary form is to add random numbers to the data. If the string of random numbers is never repeated, the scheme is unbreakable. p. 398.
