Angela Tessoni - "Signed, Sealed, Delivered: A Look into Digital Signatures "
Abstract
In a world of that is becoming increasingly dependent on computers, the need for paper documents is becoming obsolete. Almost any document these days can be sent electronically. Now we must be concerned with how to sign these documents and how to keep these signatures secure so that they cannot be duplicated. The study of cryptography is then introduced, specifically the use of digital signatures. People can use digital signature algorithms to attach signatures to electronic documents and keep them secure to the point where the signature cannot be copied and their identity is permanently bound to that document. When describing how a digital signature works, the topics of primality testing and discrete logarithms come up. There is also the question of how secure these signatures are and what types of attacks can be made.
