Query: Universal Hashing for Information Theoretic Security   The information theoretic approach to security entails harnessing the
correlated randomness available in nature to establish security. It uses tools
from information theory and coding and yields provable security, even against
an adversary with unbounded computational power. However, the feasibility of
this approach in practice depends on the development of efficiently
implementable schemes. In this article, we review a special class of practical
schemes for information theoretic security that are based on 2-universal hash
families. Specific cases of secret key agreement and wiretap coding are
considered, and general themes are identified. The scheme presented for wiretap
coding is modular and can be implemented easily by including an extra
pre-processing layer over the existing transmission codes.
