X-News: uqvax aus.net.policy:286 From: Peter Merel <pete@extro.su.oz.au> Subject:Open Letter from Steve Orlowski Date: 18 Aug 95 06:52:32 GMT
I've received something that purports to be an open letter from Steve Orlowski. Be warned that the letter has no digital authentication with it, so it may have been forged. However it reads like the real magilla, so I'll post it here in the hope that it might inform debate a little.

Dear
Thank you for your comments on the subject of the use of encryption by private individuals.
Firstly I would like to make the point that the debate has arisen from one person's interpretation of a paper I gave at a conference on "Cryptography Policies and Algorithms" The full text of that paper is now available on the net at
http://commerce.anu.edu.au/comm/staff/RogerC/RogersHome.html
The paper carries a disclaimer at the top that the views are mine and do not necessarily represent the views of the Australian Government. The paper sets out the Government's policy on telecommunications interception, which includes the issue of the use of cryptography as:
"As a result of the Report, Australia is, among other TI issues, monitoring the impact of encryption in the telecommunications interception area and will re-examine matters in 1997 following the opening of the telecommunications area to full competition."
Telecommunications covers both voice and data communications.
The last paragraph of the paper says that there is a need to expand the cryptography debate to cover the needs of individual users in the context of the information superhighway rather than current Internet users. The paper also points out that issues such as cost, convenience and public confidence in cryptography systems will be the main issues. Public confidence is explained in terms that as long as it meets the general requirement for privacy it will be acceptable. I still maintain that the general user of the superhighway in the next century will be satisfied with a lower level of encryption which will meet that and cost and user friendliness requirements.
On specific point made in the Internet message, the paper does not suggest, either directly or by implication, that individuals should be banned from using encryption.
Regarding the use of higher level encryption, the paper supports the concept of commercial key escrow where organisations hold their own keys but may be required to provide them in response to a court order. the same would apply to individuals who could either hold there own keys or store them with a commercial body. Access to those keys would be by court order and in that respect is no different to existing procedures for the interception or seizure of telephone conversations or paper records. There is no suggestion that these basic principles, and protection of individual's rights in general, should be changed
If individuals were to use lower level encryption there would be no need for them to maintain copies of any keys for such systems. To my mind this is preferable to a requirement for keys to be maintained for all encryption systems, which could be the result if universal key escrow were introduced.
Finally on the question of interception, the general public expects a reasonable level of law enforcement to ensure the protection of their person and property. Governments are required to find a balance between this and the rights of individuals to privacy. Part of this balance is to ensure that law enforcement authorities convince a court that there is a need to carry out an interception. There is no suggestion that this fundamental approach should be changed. The paper certainly does not suggest that the Attorney-General's Department should become a centralised interception authority. In fact such a role would not be consistent with its role as a source of advice to Government.
I hope the above clarifies both the Government's policy and my personal views on these matters.
I consider this to be an open letter and have no objection to it being used as such.
Yours sincerely Steve Orlowski
