Introduction
This presentation is all about digital signatures,
its benefits, its importance, its characteristics, its
requirements, its component etc also compares
digital signatures with few other types of
signature. Various activities and steps involved in
digitally signing any document and finally will
describe the steps and benefits of the on boxsolution i.e. CoSign.

Digital Signatures???
Digital signatures are used to authenticate the contentsof electronic documents in the same way as a signature
is used to authenticate a document i.e.
paper-based signing to a digital fingerprint
This fingerprint
is unique to both the signer and the document
cannot be reused or reassigned to anyone else at any time
authenticates the originator
ascertains the integrity of the message
protects against forgery

Digital Signatures Electronic Signatures
Result of a cryptographic operation .
Technology that is used Public Key
Infrastructure (PKI).
Electronic images are physically or
logically attached to the signed data
More secure towards data integrity and
non-repudiation of transactions.
Easy to forge

CoSign????CoSign is simple-to-use and quick to deploy, digital-
signature solution, while ensuring protection against
signature forgery. It supports digital signatures in various
applications like Microsoft Word, Adobe Acrobat, TIFF images
and leading Content Management Systems.

Technology behind CoSign Digital
Signatures
CoSign uses Public Key Infrastructure(PKI) for generatingdigital signatures. In PKI (asymmetric cryptography) each user
has a key pair, a private key and a public key. As the name
suggest the private key is solely kept by the signer while his
public key is available to all, whosoever want to validate his
signature. The owner of the private key digitally signs electronicinformation, while the holders of the corresponding public key
use it to verify the authenticity of the signature. A cryptographic
function known as hashing is used for both creating and
validating a digital signature.

Technology behind CoSign Digital
Signatures
The hast function-an algorithm uniquely creates a fingerprintwhich is appended to the message which is being sent to the
recipient. In case if any changes are made to the message it will
reflected as corrupted digital signature.
It also authenticates the user be a Certification Authority (CA).
There must be a proper way of managing these key-pair and
CoSign provides such facility.

PKI digital signatures vs. CoSign
PKI based solutions are expensive and difficult to deploy as itconsists many component so integrating them is a complex,
lengthy and prohibitive process. While Cosign provides a cost
effective and easy to use solution to the problems with the PKI
based solutions.
