Security Enhancements in Data Storage and Transfer: DNA Encryption Algorithm Combined with Blockchain Technology

Abstract

In the digital era, data protection is crucial due to the prevalence of cybercrime and unauthorized access techniques. Conventional encryption technologies, while still effective, are increasingly vulnerable to sophisticated cyber-attacks and quantum computing. This paper presents a novel method for enhancing the security of data storage and transmission by combining blockchain technology with a DNA encryption algorithm. The proposed approach leverages the intricate and distinctive characteristics of DNA sequences along with the robustness and immutability of blockchain technology to significantly improve data security. The complexity and vast diversity of the genetic code make decrypting data extremely difficult without the associated key. This method ensures the security of data from unauthorized access while allowing network tracking through the decentralized and immutable ledger system of the blockchain. An in-depth examination of blockchain architecture, DNA encryption, and the potential of combining these technologies for secure data transport and storage is provided. Results indicate that this hybrid approach outperforms traditional encryption and standalone blockchain technology in key metrics. The encryption time for DNA encryption combined with blockchain technology is 0.65 seconds, compared to 0.5 seconds for traditional encryption and 0.75 seconds for blockchain technology. Decryption times are 0.55 seconds for DNA encryption with blockchain, 0.45 seconds for traditional encryption, and 0.7 seconds for blockchain technology. Data integrity is highest with DNA encryption combined with blockchain at 99.9%, compared to 99% for traditional encryption and 99.5% for blockchain technology. Scalability is high for both blockchain technology and DNA encryption combined with blockchain, whereas traditional encryption is moderately scalable. The security level is extremely high for DNA encryption combined with blockchain, very high for blockchain technology, and high for traditional encryption.
