Product Review
Dominic Welsh's Codes and Cryptography takes a wide approach and explores the mathematical foundations of this field, considering information theory, entropy, and the encoding of messages. From these roots in information and communication theory, Welsh then moves on to topics in cryptography, including public key cryptography and digital signatures. The text also offers practice exercises along with their solutions.
There is plenty of mathematics here, making this a book for specialists (a result of the author's experience teaching undergraduates at Oxford). Between the formulas, though, the author conveys a genuine enthusiasm for his subject and for the history of cryptography. The text includes an extensive bibliography of sources in the field.
Product Review
' This excellent book can be strongly recommended it is so well written that it could be read solely for interest and enjoyment.' Times Higher Educ. Supplement
'This authoritative book has a well structured approach. essential reading for the engineer concerned with safe-guarding as well as communicating information.' IEE Review
' an exciting introduction to codes and cryptography,but also manages to provide clear introductory accounts to a number of vitally important and closely related mathematical topics the most significant of which is computational complexityIt is surprising that a book can contain such a high rate of information per page and still be readableThis excellent book can be strongly recommended to anyone with the appropriate mathematical background.'Times Higher Education Supplement
Customer Reviews & Comments
This small gem caught my eye because of its publisher (Oxford, well known for publishing excellent textbooks on scientific subjects), and its simple title. 'Code and cryptography'. Nothing fancy or flashy. Having picked it up, I was pleased to see it's in the style of Shannon's 1948 paper which introduced the science of information theory. I'm especially grateful to the author for his judicious use of simple examples to illustrate complex topics, and when coupled to the clear mathematical language, this book is extremely effective at conveying the material. Be forewarned, it is dense and heavy, and requires you to really get actively engaged in the material. The presentation of theorems is very textbook, which is useful, but nothing is handed to you so easily. Definitely go into it with a ready mindset, and a good grasp of basic mathematics. However, if you step up to it, it can be a very worthwhile exercise. The book's small size hides its power. Highly reccomended.
