A Study On Network Security and Cryptography

The concept of network security is the use of cryptography to ensure the privacy of message contents and safeguard data while it is being transmitted wirelessly. Data security is the main element of safe data transport across unreliable networks. Access to data within a network is one aspect of network security that is managed by the network administrator. Network security is used in many computer network areas, such as public and private networks used by organisations, enterprises, and academic institutions. These networks fall into one of two categories: private or public. Network security is in charge of making sure that the entire network is secure, not just individual endpoints. Businesses, banks, corporations, and governmental entities are just a few of the organisations that use network security.In cryptography, the received message can only be decrypted by the one who has the decipher key. When the sender applies a hash function, a cryptographic operation, to the original message, this is achieved. The value of a hash function, which is a mathematical representation of the information, is determined by the recipient once it has reached them. Cryptography is a technique used to ensure data security. As a result, cryptography might be considered a novel technology that is essential to network security.
