Abstract

Traditional data authentication systems are sensitive to single bit changes and so are unsuitable for message spaces that are naturally fuzzy where similar messages are considered the same or at least indistinguishable. In this paper, we study unconditional secure approximate authentication. We generalize traditional universal hashing to fuzzy universal hashing and use it to construct secure approximate authentication for multiple messages.
