Abstract: Security has been the fundamental apprehension during information transmission and storage. Communication network is inordinately susceptible to intrusion from unpredictable adversaries thus threatening the confidentiality, integrity and authenticity of data. This is where cryptography facilitates us and encodes the original message into an incomprehensible and unintelligible form. DNA cryptography is the latest propitious field in cryptography that has transpired with the advancement of DNA computing. The immense parallelism, unrivalled energy efficiency and exceptional information density of DNA molecules is being traversed for cryptographic purpose. Currently, it is in the preliminary stage and necessitates avid scrutinisation. The foremost hindrance in the field of DNA cryptography is computational complexity and lack of sophisticated laboratories. In this paper, we discuss the existing DNA cryptographic approaches and compare their achievements and limitations to provide a better perception. In the end, a modified version of the DNA cryptography combined with soft computing is also suggested.
