This paper presents alternative security methods based on DNA. From the alternative security methods available, a DNA algorithm was implemented using symmetric coding in BioJava and MatLab. As results, a comparison has been made between the performances of different standard symmetrical algorithms using dedicated applications. In addition to this, we also present an asymmetric key generation an...

bioinformatics, through the sequencing of the full genomes for many species, is increasingly relying on efficient global alignment tools exhibiting both high sensitivity and specificity. many computational algorithms have been applied for solving the sequence alignment problem. dynamic programming, statistical methods, approximation and heuristic algorithms are the most common methods applied t...

DNA (deoxyribonucleic acid) computing that is a new computation model based on DNA molecules for information storage has been increasingly used for optimization and data analysis in recent years. However, DNA computing algorithm has some limitations in terms of convergence speed, adaptability, and effectiveness. In this paper, a new approach for improvement of DNA computing is proposed. This ne...
