Modern cryptography is concerned with the construction of systems that are
robust against malicious attempts to make these systems deviate from their
prescribed functionality. Indeed, the scope of modern cryptography is very
broad, and stands in contrast to classical cryptography, which has been
associated with the single problem of providing secret communication over
insecure communication media. Foundations of Cryptography surveys the main
paradigms, approaches and techniques used to conceptualize, define and provide
solutions to natural cryptographic problems. The author starts by presenting
some of the central tools; that is, computational difficulty (in the form of
one-way functions), pseudorandomness, and zero-knowledge proofs. Based on these
tools, the emphasis is shifted to the treatment of basic applications such as
encryption and signature schemes as well as the design of general secure
cryptographic protocols. The author has created a unique overview that includes
well over 100 references. The accent is on the clarification of fundamental
concepts and on demonstrating the feasibility of solving several central
cryptographic problems. Foundations of Cryptography is an invaluable resource
for all students, researchers and practitioners interested in the foundations
that underpin modern cryptography.
