An Innovative Method for DNA Cryptography-Based Digital Signature Verification

Online services have become increasingly important in our daily lives in recent years. Despite its advantages, the communication network has some security problems. The security components include data integrity, user authentication, and information confidentiality. To comply with all of these standards, the sensitive material must first be signed electronically by the sender and then authenticated by the intended recipient. Therefore, more research on digital signatures is needed to improve data security and transfer data validity. In this study, a secure online signature algorithm is developed. To create secure digital signatures, it is necessary to combine safe hash codes with ElGamal, DNA, and crypto techniques. Then, the crypto time complexity of our study methodology and the current PlayGamal method are compared. By utilizing the SHA algorithm, a safe hash code is produced, and the computational complexity of the encryption method is reduced by hybridization.
