DNA cryptography

DNA cryptography is a new promising field in cryptography which emerged with the progress of DNA computing. The concept of massive parallelism and large information density inherent in DNA molecule are exploited for cryptographic purposes. Currently, the main difficulties of DNA cryptography are the requirement of high tech biomolecular laboratory and computational complexity. In this paper, a new parallel cryptography technique is proposed using DNA molecular structure, one-time-pad scheme and DNA hybridization technique which certainly minimizes the time complexity.
