The protection of sensitive information against unauthorized access
or fraudulent changes has been of prime concern throughout the
centuries. Modern communication techniques, using computers
connected through networks, make all data even more vulnerable to
these threats. In addition, new issues have surfaced that did not
exist previously, e.g. adding a signature to an electronic
document. Cryptology addresses the above issues - it is at the
foundation of all information security. The techniques employed to
this end have become increasingly mathematical in nature.
Fundamentals of Cryptology serves as an introduction to modern
cryptographic methods. After a brief survey of classical
cryptosystems, it concentrates on three main areas. First, stream
ciphers and block ciphers are discussed. These systems have
extremely fast implementations, but sender and receiver must share
a secret key. Second, the book presents public key cryptosystems,
which make it possible to protect data without a prearranged key.
Their security is based on intractable mathematical problems, such
as the factorization of large numbers.The remaining chapters cover
a variety of topics, including zero-knowledge proofs, secret
sharing schemes and authentication codes. Two appendices explain
all mathematical prerequisites in detail: one presents elementary
number theory (Euclid's Algorithm, the Chinese Remainder Theorem,
quadratic residues, inversion formulas, and continued fractions)
and the other introduces finite fields and their algebraic
structure. Fundamentals of Cryptology is an updated and improved
version of An Introduction to Cryptology, originally published in
1988. Apart from a revision of the existing material, there are
many new sections, and two new chapters on elliptic curves and
authentication codes, respectively. Fundamentals of Cryptology will
be of interest to computer scientists, mathematicians, and
researchers, students, and practitioners in the area of
cryptography.
