Abstract

Cryptography consists of mathematical techniques designed to protect communications and rests upon a simple but revolutionary mathematical idea. The Concise Oxford Dictionary defines cryptography as the 'art of writing or solving codes'. Without attempting to provide a perfect definition of modern cryptography, it could be said that one of the core goals of the practice of cryptography is ensuring the confidentiality, integrity and availability of data in computer systems. If we consider communications secrecy, we can divide cryptography into two main broad areas: private key (symmetric-key) and public key (asymmetric-key) techniques. 3 MLJ at ii Public key cryptography is mainly relied upon especially for the creation of digital signatures. It allows parties to set up a secure transmission channel with no prior exchange of secret keys. Each user generates a pair of public and private keys. The former is used for encryption and the latter for decryption. This Public Key Infrastructure proves authenticity of users' keys by means of a 'Certificate'. On an organisational level, it is a set of authorities known as 'Certification Authorities' ('CAs') issuing certificates who are to be the trusted third parties.
