Different Features Of Cryptography

Cryptography is the study and practice of secret writing and communication. It could also be said to be art and as such provide the keys and locks of the Information Age. Secret writing developed into two different branches. One of them is steganography, derived from Greek words meaning “covered” and “to write”. Cryptography was created in parallel to this. It originates from the Greek word of kryptos meaning “hidden”. Whereas in steganography the purpose is to hide a message, so that it cannot be found easily, in cryptography the aim is to hide the meaning of the message through the means of encryption. These all are part of secret writing. Written with the purpose of covering or hiding the message so that no other individual, except the …show more content…
In a general level the functions of scrambling and unscrambling messages can be called encryption and decryption, thought depending on which technique is used there exists a more specific vocabulary. The opposite of cryptography is cryptanalysis, the science of breaking codes and ciphers. One of the earliest cryptanalytic techniques is frequency analysis, a process which was first described by “the philosopher of Arabs, al-Kindi” in the ninth century. The basis of this technique is the analysis of the frequency of the characters that appear in the ciphertext and their relation to the …show more content…
In this paper I claim, that because cryptography has evolved so greatly and significantly during it’s history, it will continue to adapt more in the future and will be used for a number of different reasons form recreational cryptography to full blown warfare. I will also attempt to explain in a clear way some of the different types of cryptography and cryptanalysis through historical examples and attempt to make a hypothesis about the future of cryptography, codes, cyphers, and everything that goes into keeping secrets secret. Now days, because of the technological advancements in the field, cyphers are barely more than some light fun. Now most of cryptography is based on encryption and safekeeping of virtual information. Some people believe that, because of recent technological developments, including quantum computing, cryptography is running out of
