Information security in the present era is becoming very
important in communication and data storage. Data
transferred from one party to another over an insecure
channel (e.g., Internet) can be protected by cryptography.
The encrypting technologies of traditional and modern
cryptography are usually used to avoid the message from
being disclosed. Public-key cryptography usually uses
complex mathematical computations to scramble the
message. / A digital signature is an important public-key primitive that
performs the function of conventional handwritten signatures for
entity authentication, data integrity, and non-repudiation,
especially within the electronic commerce environment.
Currently, most conventional digital signature schemes are based
on mathematical hard problems. These mathematical algorithms
require computers to perform the heavy and complex
computations to generate and verify the keys and signatures. In
1995, Naor and Shamir proposed a visual cryptography (VC) for
binary images. VC has high security and requires simple
computations. The purpose of this thesis is to provide an
alternative to the current digital signature technology. We
introduce a new digital signature scheme based on the concept of
a non-expansion visual cryptography. A visual digital signature
scheme is a method to enable visual verification of the
authenticity of an image in an insecure environment without the
need to perform any complex computations. We proposed
scheme generates visual shares and manipulates them using the
simple Boolean operations OR rather than generating and
computing large and long random integer values as in the
conventional digital signature schemes currently in use.
