20Cryptography is the practice and study of techniques for secure communication in the presence of third parties (called adversaries). More generally, it is about constructing and analyzing protocols that overcome the influence of adversaries and that are related to various aspects in information security such as data confidentially, data integrity, authentication, and non- repudiation. Modern cryptography intersects the disciplines of mathematics, computer science, and electrical engineering. Applications of cryptography include ATM cards, computer passwords, and electronic commerce.
Basic example to understand how cryptography works is given below:
SECURE (plain text)
+1(+1 next letter, for example, the letter ““T”” is used for ““S”” to encrypt.) TFDVSF (encrypted text)
+=logic=> Algorithm 1=Factor=> Key
Look at the following output. What did the hacker accomplish?
