\subsection*{Preface}

This is Volume~IV, Release 1, of the {\sl Abstracts in Cryptology.} This release contains approximately one thousand abstracts and references to books, papers, articles, technical reports, letters, and other literature pertaining to cryptology. The core references deal with secrecy, authentication, cryptanalysis, protocol, and so on. Other subjects having some coverage include random number generation, number theory (factoring and primality testing), zero-knowledge proofs, data compression, and complexity theory. I believe that all works referenced are publicly available.

Other volumes covering different decades are also available, but are not as complete as the current volume. Volume~I covers literature prior to 1900, Volume~II covers 1900--1919, Volume~III cover 1920--1929, Volume~IV covers 1930--1939, Volume~V covers 1940--1949, Volume~VI covers 1950--1959, Volume~VII covers 1960--1969, Volume~VIII covers 1970--1979, Volume~IX covers 1980--1989, Volume~X covers 1990--1994, and Volume~XI covers 1995--1999.

I regret that I am unable to supply copies of works referenced, nor can I specify where individual works may be obtained. Most of the books referenced should be available from a university or large public library. Most of the journal articles can be obtained by the interloan services of a library. The technical reports can usually obtained by directly contacting the author or institution concerned. Many of the technical reports from 1985 onwards are available on-line using the World-Wide-Web, gopher, and ftp systems.

Some journals are not covered very well in this release: notable omissions are {\em Cryptologia\/} and the {\em Journal of Cryptology.} If somebody with access to these journals can send me abstracts for the papers in them I will include them in the document for the next release.

If you know of any relevant document not listed here please send me the title, author, and journal or publisher, and if possible send an abstract. I am also happy to receive complete papers.

This document is designed to be printed using the \LaTeX\ typesetting system.
