In this paper, we propose an improved digital signature algorithm to verify data integrity while storing data in a database. When a message is received, the recipient may want to verify that the message has not been altered in transit, and the recipient may also want to verify the identity of the sender, both of which are achieved through digital signature algorithms. A digital signature proves to the recipient or to a verifier that the message was actually signed. By creating a digital signature on stored data and programs, the integrity of the data and programs can be verified later. In this paper, we proposed a secure key generation, new signature method and modified algorithm, and an efficient way to certify and sign a message through a public key cryptosystem. A new algorithm was developed by introducing an improved signature authentication formula, and this signature and verification process was performed with a public key. In addition, new signature processes such as signature, verification, and comparison, and new parameters for digital signature tasks to perform verification processes were introduced to perform signature creation and verification methods. The proposed signature algorithm compares the results of the signature and verification process, and confirms the efficiency in terms of document integrity and key generation time, signing time, and verification time. |
