Cryptographic Digital Communication
Abstract
The fundamentals of cryptographic digital systems are reviewed. The basic types of ciphers are defined and discussed. The remainder of the report examines the word and bit error rates in digital communication systems with block or stream ciphers. Upper bounds and ensemble averages of the error rates are obtained for both ciphers. The effect of modulation type on the degradation in communication system performance caused by the addition of cryptography is analyzed. A comparison is made between block and stream ciphers with respect to their effects on degradation.
