I know it is not relevant to the development of policy but I can't help
smiling at:
"During this period, around 2600 interception warrants were issued by the
Home Secretary."
I assume someone involved in drafting it has heard of 2600.
More to the point, I don't see that section 14 of the Statement implies a
compulsory infrastructure-based key-recovery GAK. In fact it rules it out
for private users and unlicensed providers. To my non-lawyerly mind it says:
"if you have an encrypted message that we think is evidence, and you don't
tell us what it says when we ask you, then we will put you in prison". Which
may be bad news but surely is no different from the current law about
witholding evidence? This seems to be, just about, in line with the
pre-election Labour Party document. There is no stated requirement for
anyone other than a licensed encryption provide (& I strongly suspect they
will be like hen's teeth) to go out of their way to make prior arrangements
to let the spooks in.
Of course it still leaves room for infrastructure GAK for licensed
providers if the Government wants it; and we know that some parts of it
want it and some don't. So I guess it is down to Whitehall infighting Or
"New Open Government" as it is properly called in New Britain (which I
always thought was somewhere off Papua)
The Statement:
> 14. In response to these concerns, the Government intends to introduce
legislation to enable law enforcement
> agencies to obtain a warrant for lawful access to information necessary to
decrypt the content of
> communications or stored data (in effect, the encryption key). This does
not include cryptographic keys used
> solely for digital signature purposes. The new powers will apply to those
holding such information (whether
> licensed or not) and to users of encryption products. They will be
exercisable only when appropriate authority
> has been obtained (for example, a judicial warrant for the purpose of a
criminal investigation or, in the case of
> interception of communications, a warrant issued by a Secretary of State)
and will be subject to strict controls
> and safeguards.
The Old Labour Policy:
> > It is important that privacy is rigorously protected over the new
> networks, for both personal and commercial
> reasons. We do not accept the "clipper chip" argument developed in the
United States for the authorities to be
> able to swoop down on any encrypted message at will and unscramble it.
> The only power we would wish to give to the authorities, in order to
pursue a defined legitimate anti-criminal
> purpose, would be to enable decryption to be demanded under judicial
warrant (in the same way that a warrant
> is required in order to search someone's home).
(And my favourite bit)
> > Attempts to control the use of encryption technology are wrong in
> principle, unworkable in practice, and
> damaging to the long-term economic value of the information networks.

similarly, may be effectively unbreakable
