Encryption is a very important part in the study of cryptography. Encryption is a very important section in computer science . Cryptography is the science that deals with ciphers, cryptograms and codes. In the study of cryptography, these codes and ciphers are analyzed and deciphered into simple meanings. So, basically, the process of transforming the plain information into coded ones is known as encryption. The motive is to hide the information from every Tom, Dick and Harry so that the valuable information remains only in the hands of few special persons who deserve those.
- The application of encryption:
The use of encryption has been very effective and successful in various fields. Military and government have immensely utilized the science of encryption for various aspects. It helps them to hide lots of important information, which demand to be secret. Encryption helps in the process of secret communication too.
Besides military and government, some of the other fields where encryption is very useful include mobile telephone networks, Internet e-commerce, bank automatic teller machines and many other fields. Encryption is also used to prevent piracy of different software copies and also in several engineering fields. Encryption is in fact a very necessary aspect in the field of wireless communication. In wireless communication, messages can be hacked very easily. So encryption is very much needed in these cases.
