DNA Linear Block Codes: Generation, Error-detection and Error-correction of DNA Codeword
In modern age, the increasing complexity of computation and communication
technology is leading us towards the necessity of new paradigm. As a result,
unconventional approach like DNA coding theory is gaining considerable
attention. The storage capacity, information processing and transmission
properties of DNA molecules stimulate the notion of DNA coding theory as well
as DNA cryptography. In this paper we generate DNA codeword using DNA (n, k)
linear block codes which ensures the secure transmission of information. In the
proposed code design strategy DNA-based XOR operation (DNAX) is applied for
effective construction of DNA codewords which are quadruples generated over the
set of alphabets {A,T,G,C}. By worked out examples we explain the use of
generator matrix and parity check matrix in encryption and decryption of coded
data in the form of short single stranded DNA sequences. The newly developed
technique is capable of detecting as well as correcting error in transmission
of DNA codewords from sender to the intended receiver.Comment: 23 pages, 1 figure, 5 table
