Public key cryptography
The most commonly-used encryption methodology today is public key cryptography, explained Stephen Lewis, conceived by the genius of Cliff Cox in the early 1970s in GCHQ and developed around the world by mathematicians who have achieved fame for their work such as Schneier, Difffie, Hellman and, of course, Rivest, Shamir and Adleman (RSA).

In simple terms, encryption is the process of scrambling and unscrambling information using secret codes or keys. Encryption is primarily focused on protecting information which is stored and communicated digitally using computers over the Internet or other communications links.
Increasingly, commercially-developed systems for encryption built to exacting government standards are being used to protect information classi?ed as con?dential and restricted under UK government protective markings, said Mr Lewis.
