Effective design of a parametrical security model for digital signatures using cryptography

Digital signature authentication scheme provides secure communication between two users. A valid digital signature gives a recipient reason to believe that the message was created by a known sender, such that the sender cannot deny having sent the message (authentication and non-repudiation) and that the message was not altered in transit (integrity). The focus Synopsis of this paper is to discuss how to protect communications that occur in a transaction so as to guide against fraudsters and in other cases where it is important to detect forgery or tampering.
