ENCRYPTION SYSTEM WITH INDEXING DNA CHROMOSOMES CRYPTOGRAPHIC ALGORITHM

摘要

DNA has a great cryptographic strength, its binding properties between nucleotides bases (A-T, C-G) offer the possibility to create self-assembly structures which are an efficient means of executing parallel molecular computations. Our work is based on the development of the new encryption system with indexing DNA chromosomes cryptographic algorithm using MATLAB Bioinformatics Toolbox. This toolbox offers support for developing DNA cryptographic operations and providing more secure cryptographic algorithms. The algorithm is based on the idea to use DNA chromosomes as one-time-pad structures and index them in order to encrypt the plaintext message. Our work is based on the complexity of the development of the new encryption system with indexing DNA chromosomes cryptographic algorithm.
