Description

A key technique that supports the security of data in computer networks is cryptography. The process of transforming regular plain text into unintelligible text and vice versa is known as cryptography. It is a technique for keeping and sending data in a specific format that only the intended audience can read and process. Cryptography can be used for user authentication in addition to safeguarding data against theft and modification. Cryptographic system design must be founded on solid principles. There are several difficulties and research possibilities in Internet security. Serious security and privacy concerns are preventing potential uses like online voting, universal access to medical records, and pervasive e-commerce. Hacker attacks on websites and personal computers are on the rise, which only serves to underline how vulnerable the current computer and network infrastructure is. The function that cryptography plays in ensuring information security for technologies like the Internet, mobile phones, payment cards, and wireless local area networks is thoroughly explained in this book.
