`a perfect pocket primer for anybody interested in cryptography.' Simon Singh
Book Description
This book is a clear and informative introduction to cryptography and data protection - subjects of considerable social and political importance. It explains what algorithms do, how they are used, the risks associated with using them, and why governments should be concerned. Important areas are highlighted, such as Stream Ciphers, block ciphers, public key algorithms, digital signatures, and applications such as e-commerce. This book highlights the explosive impact of cryptography on modern society, with, for example, the evolution of the internet and the introduction of more sophisticated banking methods.
Customer Reviews & Comments
The book is good as befits its subtitle. Indeed, a very short introduction, with only a minimal evocation of maths background. But there is enough qualitative explanation so that you can understand the broad historical development. From the Caesar Cipher to a Simple Substitution Cipher to a Vigenere Square Cipher. Then, the text goes into modern ideas, all of which involve using computers to encrypt and decrypt. Notably the invention of the public key system. Truly quite different from all that preceded it. There is also a brief foray into quantum computing. Here, it is mostly conceptual; discussing the possible potential, since current implementations are very rudimentary. The text has no mention of man in the middle attacks and how to guard against these. Pity. Because while this is a very hard attack to perform, if it can done, then it is very hard to defend against. One of the promises of quantum computing is that it inherently offers a simple detection, based on quantum interference by the attacker.
