A Novel Two Layer Encryption Algorithm Using One-Time Pad and DNA Cryptography

A multi-level random key cryptosystem based on DNA encoding and state-changing mealy machine

“…This proves that the principles of DNA cryptography can be used widely and they also can be used on different formats of data. Hazra et al [18] combined the concepts of One Time Pad and DNA cryptography to create a two layered security system that uses both the aforementioned concepts on textual data to encrypt and transfer the data securely. They used a DNA permutation table to encrypt the data which they receive after completing the first step of encryption using one time pad.…”

Increasing Randomization of Ciphertext in DNA Cryptography

“…This encoding table is a 24 * 4 matrix of 96 American Standard Code for Information Interchange (ASCII) characters consisting of alphabets, numbers, and special characters. Later this table was used and extended by other researchers [11]- [13]. It is evident that the utilization of this table in an algorithm has improved the randomness of ciphertext and consequently enhanced the system security.…”

“…The next attributes have been analyzed for experimentation purposes, and the results indicate a 15% improvement in accuracy, whereby a more complex encoding can effectively improve the accuracy of the intrusion detection system. In [13] and [14], a Dynamic DNA sequence table is used in combination with OTP to improve data security. The attacker must execute all possible DNA sequence variations before getting original data, which is supposed to be very difficult.…”
