Omega Network Pseudorandom Key Generation Based on DNA Cryptography

Abstract

Eliminating the risk of bugs and external decryption in cryptographic keys has always been a challenge for researchers. The current research is based on a new design that uses an Omega network-based pseudorandom DNA key generation method to produce cryptographic keys for symmetric key systems. The designed algorithm initially takes two random binary numbers as inputs to the Omega network design, generating an output of 256 symmetric keys. The Omega network uses the concept of the central dogma of molecular biology (DNA and RNA properties), including DNA replication (for DNA) and the transcription process (for RNA). The NIST test suite is applied to test the security properties of the proposed design. According to the study’s findings, the suggested design is significantly suited to achieve the NIST test security properties and passes all of the NIST recommended tests.
