17) Digital Signature
Objective:
This project has been developed keeping in view the security features that need
to be implemented in the networks following the fulfillment of these objectives:
> To develop an application that deals with the security threats that arise in the
network.
> To enable the end-users as well as the organizations come out with a safe
messaging communication without any threats from intruders or unauthorized
people.
> To deal with the four inter-related areas of network security namely Secrecy,
Authentication, Non-repudiation and Integrity.
Project Overview
This application makes use of Digital Signature Algorithm (DSA) along with a
hash function. The hash code is provided as input to a signature function along
with a random number generated for this particular signature. The signature
function also depends on the senders private key and a set of parameters known to
a group of communicating principals. This set constitutes a global public key. The
result is a signature consisting of two components.

At the receiving end, verification is performed. The receiver generates a quantity
that is a function of the public-key components, the senders public key, and the
hash code of the incoming message. If this quantity matches with one of the
components of the signature, then the signature is validated.
This application makes sure that the security services Authentication, Secrecy,
Integrity, and Non-repudiation are provided to the user.

Intruders can modify the messages or the receiver himself may
modify the message and claim that the sender has sent it.

For example, suppose that A sends an authenticated message
to B. Consider the following disputes that could arise:
It must be able to verify the author and the date and time of
the signature.

The Digital Signature Standard (DSS) makes use of the Secure
Hash Algorithm (SHA) to present a new digital signature
technique, the Digital Signature Algorithm (DSA).It uses an
algorithm that is designed to provide only the digital signature
function. Unlike RSA, it cannot be used for encryption or Key
exchange. Nevertheless, it is a public-key technique.
