MODERN CRYPTOGRAPHY TECHNIQUES FOR INCREASE NETWORK SECURITY

Network Security & Cryptography is a concept to protect network and data transmission over wireless network.Data Security is the main aspect of secure data transmission over unreliable network. Network security involves theauthorization of access to data in a network, which is controlled by the network administrator. Users choose or are assignedan ID and password or other authenticating information that allows them access to information and programs within theirauthority. Network security covers a variety of computer networks, both public and private, that are used in everyday jobsconducting transactions and communications among businesses, government agencies and individuals. Networks can beprivate, such as within a company, and others which might be open to public access. Network security is involved inorganizations, enterprises, and other types of institutions. In this paper we also studied cryptography along with itsprinciples. Cryptographic systems with ciphers are described.The cryptographic models and algorithms are outline
