The first DNA-based molecular parity generator/checker, used for error detection through data transmission with fluorescent and visual readouts, has been constructed. The erroneous transmission can be readily distinguished by the naked eye using the G-quadruplex DNAzyme as a signal reporter of the visual outputs.

In this article, an encryption algorithm with an error detection technique is presented for highly secured reliable data transmission over unreliable communication channels. In this algorithm, an input data is mapped into orthogonal code first. After that the code is encrypted with the help of Linear Feedback Shift Register (LFSR). The technique has been successfully verified and synthesized using Xilinx by Spartan-3E FPGA.

Data transmitted from one location to the other has to be transferred reliably. Usually, error control coding algorithm provides the means to protect data from errors. Unfortunately, in many cases the physical link can not guarantee that all bits will be transferred without errors. It is then the responsibility of the error control algorithm to detect those errors and in some cases correct them so that upper layers will receive error free data. The polynomial code, also known as Cyclic Redundancy Code (CRC) is a very powerful and easily implemented technique to obtain data reliability. As data transfer rates and the amount of data stored increase, the need for simple and robust error detection codes should increase as well. Thus, it is important to be sure that the CRCs in use are as effective as possible. Unfortunately, standardized CRC polynomials such as the CRC-32 polynomial used in the Ethernet network standard are known to be grossly suboptimal for important applications, (Koopman, 2002). This research investigates the effectiveness of error detection methods in data transmission used several years ago when we had to do with small amount of data transfer and data storages compared with the huge amount of data we deal with nowadays.  A demonstration of erroneous bits in data frames that may not be detected by the CRC method will be shown. A corrective method to detect errors when dealing with humongous data transmission will also be given.

This chapter is devoted to the modeling of aircraft data transmission via low-orbit satellites. Satellite communication channel models were designed, which allow to investigate BER dependencies on the type of signal modulation, information transfer rate, signal power, antenna diameters, and nonlinearity of a high power amplifier. Impact of a modulation type (BPSK, QPSK, 8PSK, 16QAM), Eb / N0, satellite transponder amplifier gain without and with coding on a BER was investigated. Effectiveness of error detection and correction was analyzed using classic linear block and convolutional codes. Free space path loss, AWGN, and radio frequency satellite channels were considered. MIMO 2 × 1 and 3 × 2 fading uplink/downlink channels with antenna diversity were analyzed. Results were compared with AWGN uplink/downlink channels. On the base of these models, channels integrity was investigated.

Suggested Algorithm

This article describes how the simplicity of data transmission made eavesdropping by malicious people easier. This became one the flaws of computer security that needs to be handled. In order to establish a secure data communication, many data security techniques were developed to ensure privacy, integrity and authenticity. One of the techniques developed was to fulfill authentication with a message authentication code (MAC) that was defined by the National Institute of Standards and Technology. It is still a powerful data integrity and authentication tool that provides better protection than error detection codes or checksums. In this article, the authors propose a new cipher-based message authentication code (CMAC) algorithm. Their proposed algorithm, termed SEC-CMAC, is based on a previously developed symmetric evolutionist ciphering algorithm named symmetrical evolutionist ciphering (SEC). Compared to the well-known previously developed MAC, their suggested algorithm proved to be robust and fulfill some security requirement by resisting an exhaustive key search and mac forgery attacks.
