There are many security aspects in data communication, while transferring data in a distributed network. Encryption is also a way to provide security in data communication using a key. Several techniques are already introduced for encryption as well as decryption. Some of them do not provide so much security as required, but many techniques are very useful and can be implement to be made more secure the authors' data. Brute force attack is the most common attack, which makes a threat in data communication and cryptanalysis also make easy to break the code.
