Traditionally, cryptography has offered a means of communicating sensitive (secret, confidential or private) information while making it unintelligible to everyone except for the message recipient. Cryptography, as was used in ancient biblical times, offered a technique in which text was manually substituted within a message as a means of hiding its original content.
Many years later, during the Second World War, cryptography was extensively used in electro-mechanical machines (such as the infamous Enigma machine). Nowadays, cryptography is ever more pervasive heavily relying on computers supported by solid mathematical basis.
Cryptography, as the name implies, attempts to hide portions of text from malicious eyes using a variety of methods. In theory, the concept sounds ideal but real life experience has proven that a multitude of factors and environmental aspects come into play which have a negative impact on the cryptographic key’s strength.
Conventional means are unable to provide a bullet proof solution to fully address diverse attack scenarios attempting to exploit cryptography’s inherent vulnerabilities. This paper discusses traditional techniques while focusing on the white box cryptography implementation.
