WebIntroduction. Throughout the text we have repeatedly stressed the relevance of cryptography to modern life and have used real-life situations to illustrate some of the important issues. This chapter contains a number of disjointed situations where the use of cryptography facilitates the provision of a secure service. WebNov 4, 2024 · Symmetric cryptography itself is a process that’s thought to have been created thousands of years ago. An early example of symmetric encryption — and probably the best-known symmetric cipher — is attributed to the Roman General Julius Caesar. This particular cipher is aptly known as the Caesar Cipher (more on that in a couple of minutes).

Although cryptography has a long and complex history, it wasn't until the 19th century that it developed anything more than ad hoc approaches to either encryption or cryptanalysis (the science of finding weaknesses in crypto systems). Examples of the latter include Charles Babbage's Crimean War era work on mathematical cryptanalysis of polyalphabetic ciphers, redeveloped and published somewhat later by the Prussian Friedrich Kasiski.
