To break a message encrypted with private-key cryptography‚ it requires either to exploit a weakness in the encryption algorithm‚ or to try an exhaustive search of all possible keys (brute force method). Increase in key size is an e ective remedy for this. If the key is large enough (e.g.‚ 128 bits)‚ such a search would take a very long time (few years)‚ even with very powerful computers. Private-key methods are ecient and dicult to break[21]. However‚ one major drawback is that the key must be

in the transit. Cryptanalysis is the process of obtaining the original message (Plaintext) from an encrypted message (ciphertetext) without knowing the algorithms and keys used in encryption. Crypto is a tool that can be used in both good and bad ways. Some of the good crypto uses are: • Protecting the location of our troops in war zone • Protecting the nuclear launch codes • Protecting national security information • Protecting research data • Protecting a new research idea 2.
