Communication security

For secure communications, the authors propose a underwater wireless optical communications code-division multiple-access (UOWC/CDMA) system with multiple relay assistance. Relay nodes employ the Chip Detect-and-Forward (CDF) technique to prevent the difficult multiuser decoding procedure. The proposed system performance, in terms of bit-error rate (BER) and transmission confidentiality, is analyzed in our study over fading channel.

In this paper, we show that there is a certain interval of input intensity, in which the transmission coefficients overlap one to other. This behaviors of SNC can be used to generate random signals. Using the expression described the output-input power relation, the expression of the optical merge signal, carrier signal and coded-carrier signal, the overlapping region of the input intensity is numerically observed.

The rapid growth of electronic communication means that issues in information security are of increasing practical importance. Messages exchanged over worldwide publicly accessible computer networks must be kept confidential and protected against manipulation. Electronic business requires digital signatures that are valid in law, and secure payment protocols. Modern cryptography provides solutions to all these problems. This book originates from courses given for students in computer science at the Georg-Simon-Ohm University of Applied Sciences, Nurnberg.
