Hybrid approach for secure communication of data using chemical DNA

摘要

Secret communications have been made traditionally using ciphers which more or less depend upon the ability of computers to sustain attacks over them. Thus we can conclude- The security is limited in terms of computation power, if the attackers increase this computation power, which will be happening in near time, the level of security will decrease to a large extent. To avoid such kind of scenario scientists are proposing to use either completely different modes of cryptography which are not dependent much on computation power of computers or to use a hybrid approach which is derived from computer based approaches and use some elements which are independent of computer based approaches, to hide or to encrypt data. In our proposed scheme, we are using a hybrid approach which will divide data into two parts: one part is encrypted using AES-128, a traditionally strong cipher, while the other data part is hided inside synthetically manufactured DNA strand.
