This PPT provides an complete reference of "DIGITAL SIGNATURE". It gives "how the digital signature are works?" and "why we need a digital signature?". And also I include some Digital signature algorithm in a Diagrammatic format.
A digital signature is a mathematical scheme for demonstrating the authenticity of a digital message or document. 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). Digital signatures are commonly used for software distribution, financial transactions, and in other cases where it is important to detect forgery or tampering.
Digital signatures are often used to implement electronic signatures, a broader term that refers to any electronic data that carries the intent of a signature, but not all electronic signatures use digital signatures. In some countries, including the United States, India, and members of the European Union, electronic signatures have legal significance.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

3. INTRODUCTION
The authenticity of many legal, financial, and other
documents is done by the presence or absence of an
authorized handwritten signature.
“Digital Signature” is the best solution for authenticity
in various fields.
A digital signature is nothing but an attachment to any
piece of electronic information, which represents the
content of the document and the identity of the owner of
that document uniquely[5].
4. WHAT IS DIGITAL SIGNATURE?
Hash value of a message when encrypted with the private key
of a person is his digital signature on that e-Document.
Digital Signature of a person therefore varies from document
to document thus ensuring authenticity of each word of that
document.
As the public key of the signer is known, anybody can verify
the message and the digital signature.
5. WHY DIGITAL SIGNATURES???
To provide Authenticity, Integrity and Non-repudiation to
electronic documents.
To use the Internet as the safe and secure medium for e-
Commerce and e-Governance
6. BASIC REQUIREMENTS….
Private Key
The private key is one which is accessible only to the signer.
It is used to generate the digital signature which is then
attached to the message.[2]
Public Key
The public key is made available to all those who receive
the signed messages from the sender. It is used for
verification of the received message.[2]
7. BASIC REQUIREMENTS…
Digital Signature Certificate
A subscriber of the private key and public key pair
makes the public key available to all those who are
intended to receive the signed messages from the
subscriber.
But in case of any dispute between the two sides, there
must be some entity with the receiver which will allow the
receiver of the message to prove that the message was
sent by the subscriber of the key pair. This can be done
with the Digital Signature Certificate.[1]

14. CHALLENGES AND OPPORTUNITIES
Institutional overhead:
The cost of establishing and utilizing certification
authorities, repositories, and other important services,
as well as assuring quality in the performance of their
functions.
Subscriber and Relying Party Costs:
A digital signer will require software, and will
probably have to pay a certification authority some
price to issue a certificate. Hardware to secure the
subscriber's private key may also be advisable.
15. APPLICATIONS …
Electronic Mail
Data storage
Electronic funds transfer
Software Distribution
Smart Cards
MITRENET
ISDN
Time Stamped Signature
Blind Signatures
16. DRAWBACKS
The private key must be kept in a secured manner.[3]
The process of generation and verification of digital
signature requires considerable amount of time.[3]
For using the digital signature the user has to obtain private
and public key, the receiver has to obtain the digital
signature certificate also.[3]
17. CONCLUSION
Digital signatures are difficult to understand. Digital
signatures will be championed by many players that the
public distrusts, including national security agencies,
law enforcement agencies, and consumer marketing
companies.
