Cryptography

Security becomes an issue when the Internet was used as tool in commercialism . There are many security aspects and applications which range from a secure commerce to private communications (Kesler , 2010 Cryptography is one of the secure communications aspect . According to Kesler , cryptography is important for communications in order to be secure , and it is not enough by itself

Cryptography is an ancient art and the science of writing in secret code ' According to some experts ,t cryptography had come along after

the invention of writing . The new styles of cryptography had been invented after the computer communications development . Cryptography plays an important role in data and telecommunications especially in communication on unreliable medium like any network and also the Internet

The following are the feasible cryptography attacks (Conrad , 2007 Known plaintext attacks happen when the cryptanalyst has access to a plaintext and the corresponding ciphertext and seeks to discover a correlation between the two and ciphertext-only attacks happen when the cryptanalyst has access to a ciphertext but does not have access to corresponding plaintext . Chosen plaintext attacks happen against asymmetric cryptography where the cryptanalyst has access to a public key while the chosen ciphertext attack commonly performed on attacks versus public key encryption . Side channel attacks purchase additional information based on the physical implementation of a cryptographic algorithm . Brute force attack systematically attacks every possible key

There are some particular requirements on security within the application-to-application communications

Authentication . This is a process...
