Enhanced Cloud Security Through DNA-based Authentication for Data Storage and Transactions

Cloud computing has experienced rapid growth, yet data breaches and unauthorized account access continue to be significant threats. Traditional cryptographic authentication methods, although mathematically complex, often fall short in computational security. This research study integrates deoxyribonucleic acid (DNA) computing to enhance cloud security through biological authentication protocols, making it suitable for widespread use. This study introduces a DNA-based cryptographic key system that exploits synthetic DNA's dense information capacity. This system integrates biochemically secure DNA signatures with current cloud architectures, providing multi-factor authentication (MFA) and encrypted access to sensitive data and transactions. The DNA cryptography protocols developed offer robust defense against common attacks, such as password leaks. Additionally, the inherent massive parallelism in biochemical reactions supports efficient processing of authentication requests, even under heavy cloud workloads.
