	The following book has just been published by Prentice-Hall:

	Jennifer Seberry and Josef Pieprzyk, Cryptography: An Introduction to
	Computer Security, Prentice-Hall, 1988.

The book contains frequency tables for the following languages:

	Arabic, Danish, Dutch, English, Finnish, French, German, Italian,
	Greek, Hebrew, Japanese, Latin, Malay, Norwegian, Portuguese,
	Russian, Sanskrit, Spanish, and Swedish.

Further, programs similar to those being proposed have already been written as
part of the following honours theses: 

	Susy Deck, Computational Methods for Foreign Language Identification
	with Application to Cryptography, University of Sydney. 1985 

	Hui-eng Tchun, Towards the Cryptanalysis of Bhahasa Malaysia,
	University of Sydney. 1985 

	Sing Guat Ong, Towards the Cryptanalysis of Mandarin-Pinyin,
	University of Sydney. 1987 

and in a Postgraduate Diploma Students Minor Thesis:

	Robert Ramsay, More Computational Methods for Foreign Language
	Identification, with Application to Cryptography,
	University of Sydney. 1987 

This work is being continued at present by students of this Department
in some Indonesian and New Guinean languages. We also have raw data and
some statistics on a number of other languages, including Kurdish and
Serbo-Croatian.  It is expected that a number of Technical reports and
other publications of this work will be released in the near future.

If you have any queries please feel free to contact me, or our Professor
and Head, Dr. Jennifer Seberry <jennie@cs.adfa.oz@UUNET.UU.NET>.

	Regards
	Lawrie Brown.
