Description
Implementing cryptography requires integers of significant magnitude to resist cryptanalytic attacks. Modern programming languages only
provide support for integers which are relatively small and single precision. The purpose of this text is to instruct the reader regarding
how to implement efficient multiple precision algorithms.
Bignum math is the backbone of modern computer security algorithms. It is
the ability to work with hundred-digit numbers efficiently using techniques that are both elegant and occasionally bizarre. This book
introduces the reader to the concept of bignum algorithms and proceeds to build an entire library of functionality from the ground up.
Through the use of theory, pseudo-code and actual fielded C source code the book explains each and every algorithm that goes into a modern
bignum library. Excellent for the student as a learning tool and practitioner as a reference alike BigNum Math is for anyone with a background
in computer science who has taken introductory level mathematic courses. The text is for students learning mathematics and cryptography
as well as the practioner who needs a reference for any of the algorithms documented within.
Audience:
Any programmer implementing public-key cryptography algorithms needs to grasp BigNum Math. BigNum Math is for anyone with a background
in computer science who has taken introductory level mathematic courses. The text is for students learning mathematics and cryptography
as well as the practioner who needs a reference for any of the algorithms documented within.
