Computer Security and Cryptography (eBook)

Gain the skills and knowledge needed to create effective data
security systems

This book updates readers with all the tools, techniques, and
concepts needed to understand and implement data security systems.
It presents a wide range of topics for a thorough understanding of
the factors that affect the efficiency of secrecy, authentication,
and digital signature schema. Most importantly, readers gain
hands-on experience in cryptanalysis and learn how to create
effective cryptographic systems.

The author contributed to the design and analysis of the Data
Encryption Standard (DES), a widely used symmetric-key encryption
algorithm. His recommendations are based on firsthand experience of
what does and does not work.

Thorough in its coverage, the book starts with a discussion of
the history of cryptography, including a description of the basic
encryption systems and many of the cipher systems used in the
twentieth century. The author then discusses the theory of
symmetric- and public-key cryptography. Readers not only discover
what cryptography can do to protect sensitive data, but also learn
the practical limitations of the technology. The book ends with two
chapters that explore a wide range of cryptography
applications.

Three basic types of chapters are featured to facilitate
learning:

* Chapters that develop technical skills

* Chapters that describe a cryptosystem and present a method of
analysis

* Chapters that describe a cryptosystem, present a method of
analysis, and provide problems to test your grasp of the material
and your ability to implement practical solutions

With consumers becoming increasingly wary of identity theft and
companies struggling to develop safe, secure systems, this book is
essential reading for professionals in e-commerce and information
technology. Written by a professor who teaches cryptography, it is
also ideal for students.
