| Summary: | Advances in electronic computers and communications offer countless benefits to modern society however, they also present serious problems of security. These problems pose great threat to the privacy of organizations and individuals employing such systems. Eavesdropping, forgery, manipulation of information, and other computer-related crimes are bound to increase drastically due to lack of efficient security measures. A secure and less inexpensive way of protecting valuable information from being extracted or modified by unauthorized parties is to resort to cryptosystems.This study aims to develop a secure microcomputer-based communication system utilizing the RSA public-key cryptosystem. The researcher came up with a system design of a communication system implementing the RSA cryptographic scheme. A software named Cryptowriter was developed. It was specifically designed for the security of text files stored in floppy diskettes. The software was developed using different languages: MBASIC, PASCAL, DBASE II, and MUSIMP (a variant of LISP). |
