# P vs NP: The Epic Saga

P vs NP problem is one of the great unsolved problems in theoretical computer science. This problem has become broadly recognized in the mathematical community as a mathematical question because it is fundamental, important and beautiful. It is in fact one of the seven Millennium Prize Problems. If you solve this problem, you get \$1 million and become really famous among mathematicians and computer scientists. If you are evil, then you can use your proof to become richer than God, then publish your proof, reject the prize money and become extremely well respected in the mathematics community! Wait a minute, really? How can I use this to become rich? Before we answer that, let’s see what exactly is the difficulty in solving the problem. Shall we?   Continue reading “P vs NP: The Epic Saga”

# Reimann Hypothesis And Its Connection To Cryptography

Over the centuries, mathematicians have been involved in solving some of most complex problems. But what is the motivation behind that? The pursuit of truth! But The Clay Mathematics Institute thought that there should be a little more than that. So to celebrate mathematics in the new millennium, they established seven Millennium Prize Problems. The prize money for each problem is one million dollars. That’s pretty exciting! These were some of the most difficult problems over which many mathematicians were racking their brains. Reimann Hypothesis is one of them. The interesting thing about this particular problem is that it has far reaching consequences in the field of modern cryptography and internet security. Now how can an obscure and complex mathematical problem affect cryptography and internet security?   Continue reading “Reimann Hypothesis And Its Connection To Cryptography”

# Decrypting Cryptography

What’s the first thing that came to your mind when you read the title? How do you perceive the term ‘cryptography’? It has something to do with secrecy and hiding right! Anyway, cryptography is the art of protecting information by transforming it into an unreadable format. Only the people who have the secret key can decode this message. The process of transforming the information into something unreadable is called Encryption and the reverse process is called Decryption. Let’s say you have a message you want to send to your friend. The message to be encoded is called plaintext and the encrypted message is called ciphertext. The goal here is to find the most secure way of transforming the plaintext into ciphertext. How do we encrypt it? How do we make sure it remains safe even if someone happens to see it?   Continue reading “Decrypting Cryptography”
