Cloud computing enables the access of the resources such as network hardware's, storage,
applications and services that are configurable based on the demand in a network …

This paper presents several Public Key Cryptography (PKC) algorithms based on the
perspective of researchers' effort since it was invented in the last four decades. The …

ElGamal cryptosystem possess many technical challenges such as encryption of large
messages, integrity and authentication of data, non-malleability, semantic security etc. This …

This paper is concerned with the design of an improved El-Gamal cryptosystem based on
chaos synchronization. The El-Gamal cryptosystem is an asymmetric encryption algorithm …

ElGamal Cryptosystem (EC) is a non-deterministic scheme which produces different outputs
for the same input, making the cryptosystem more secure. On the other hand, the efficiency …

With continuous development of network technology, more and more attacks on system from
Internet have become more automated and caused greater damage and loss. It is important …

Cryptography has an important role in the process of data security. One of the benefits of
applying cryptography is creating a sense of security in hiding data without having to doubt …

The development of increasingly sophisticated technology with more intensive use of
computers facilitates human work activities, so that security problems arise that misuse …

Confidentiality and Integrity are two paramount objectives in the evaluation of information
and communication technology. In this chapter, we propose an arithmetic approach for …

Cryptography is a method used to establish secure data communication. The goal of
cryptography is to send data to satisfy the criteria of confidentiality, data integrity …
