The development of the World Wide Web resulted in broad use of cryptography for e-commerce and business applications. Applications of cryptography include ATM cards, computer passwords, and electronic commerce. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, and electrical engineering. More generally, it is about constructing and analyzing protocols that block adversaries various aspects in information security such as data confidentiality, data integrity, authentication, and non-repudiation are central to modern cryptography. The most common and simple way of protecting a network resource is by assigning it a unique name and a corresponding password.Ĭryptography is the science of writing in secret code. It does as its title explains: It secures the network, as well as protecting and overseeing operations being done. Network security is involved in organizations, enterprises, and other types of institutions. Networks can be private, such as within a company, and others which might be open to public access. Network security covers a variety of computer networks, both public and private, that are used in everyday jobs conducting transactions and communications among businesses, government agencies and individuals. Network security consists of the provisions and policies adopted by a network administrator to prevent and monitor unauthorized access, misuse, modification, or denial of a computer network and network-accessible resources. This is very useful in the case of Cryptanalysis. It gives different probabilities of activating or not the neural network.

Another idea is the ability of a neural network to separate space in non-linear pieces using 'bias'. The ideas of mutual learning, self-learning, and stochastic behavior of neural networks and similar algorithms can be used for different aspects of cryptography, like public-key cryptography, solving the key distribution problem using neural network mutual synchronization, hashing or generation of pseudo-random numbers. Here, content data would be used as an input data for cryptography so that data become unreadable for attackers and remains secure from them. The key formed by neural network is in the form of weights and neuronal functions which is difficult to break. Neural network and cryptography together can make a great help in field of networks security. Model for Cryptosystem Using Neural Network supports high security. So one can say that cryptography is an emerging technology, which is important for network security. Security of data can be done by a technique called cryptography. All components work together to increase the overall security of the computer network.

A network security system typically relies on layers of protection and consists of multiple components including networking monitoring and security software in addition to hardware and appliances. Network Security & Cryptography is a concept to protect network and data transmission over wireless network.

Internet has become more and more widespread, if an unauthorized person is able to get access to this network, he can not only spy on us but he can easily mess up our lives.
