IETF floats plan to PRISM-proof the Internet

Re: @stgorner: DNSSEC

Back in the late 90's when encrypted internet was first being suggested there was a "it will use PKI" and "it will use Trusted Third Parties" drive/mantra/dogma (you choose).... where this started and how it was promoted I am not sure, but it is most definitely where the problem lies!

We implemented a system with in-security designed in and "they" (whomever they were) knew it...

1. Trusted third parties aren't - some actors are broken, eg. Iranian government issues certificate for google.com

2. Trusted third parties can be leant on by governments to provide intermediate signing certificates

3. Trusted third parties can be spoofed as part of a MITM attack

The current certificate based system is both:

a) over complex, and

b) has mixed goals

is it "encryption" and "key exchange" or is it "authentication"?

IMHO what its needed is:

* very good ciphers (AES128 is ok, others are better)

* excellent key agreement or key exchange protocols (eg. ECDHE)

* separation of roles (key exchange and authentication)

* no "trusted third parties", no certificates - use DNS for pub/private keys and authentication codes - effectively "self sign". I can assert that I am me as I own my DNS.

We already have all the components to do this, and do it properly - we only need the will (we have the way).

So, we either need another upgrade to TLS/SSL to fully support a strong, no certificate, approach or we need a new protocol... if its a new protocol then on the web lets call it HTTPZ ('Z' being used to indicate encryption)

Watch out for hyperspace bypasses

Okay so we have Reed-Solomon FEC and hopefully some form of trellis convolution coding as well on the stream at bit level but where are the longitudinal checksums (CRC32, CRC48, CRC64) across the packets at block level and what about the message integrity checks (MD5, SHA1, SHA256) at whole file level?

Nominet tosses plan for shorter .uk domains in the bin (for now)

Mike Tubby
FAIL

For Nominet read "nanny state"

I was one of the people that responded to the consultation.

It was clearly a badly thought out mixture of:

a) how do we make more money from this

b) attempting to appease government with ill thought-out identity verification

c) security theatre (scanning websites, shutting them down)

d) DNSSEC (something that actually might be useful)

In what appears to be "Nominet become Nanny State" and "Nominet become policemen of the interwebs".

If we're going to have our own registrations in the .uk TLD then I want the good bits and not the bad bits...

Identity - if you want to fix this then simply say "UK companies, charities, partnerships or other legal entities only" and make registration require UK company number, charity commission number or similar - no need for envelopes sent via the post which can be diverted, or handled via accommodation addresses - what does that prove? Only that you posted it to *someone* via an address that was valid on *one* day... great!

Security - DNSSEC if you will, but optional - let me choose if I use it

Security - scanning my website? I don't think so... my website is my property... it might well have 10 million pages on it -- are they going to pay for the bandwidth?

Security - shutting down my website? what's it got to do with you, Nominet? You are *not* the internet police

Overall I give Nominet a 3/10 for a badly thought out, jumble of Nanny State proposals.

Ofcom ploughs up UK spectrum fields, reseeds them with 4G

Mike Tubby

Check your logarithms!

El Reg: "The increase in transmission power is 3dB, which is marginally more exciting when one remembers that decibels are logarithmic (so a 3dB increase is eight times the power) but it's still well within safe margins and more about increasing coverage than microwaving locals..."

I think you'll find that 3dB is a power doubling ...

dB = 10 x log(p1/p2) [log to the base 10]

So if we go from say 10 watts to 20 watts:

dB = 10 x log(20/10)

dB = 10 x log(2)

dB = 10 x 0.3010

dB = 3.01

commonly known as 3dB.

Incidentally, due to the inverse-squared power law this will increase the range by the square root of 2, for example 5Km -> 7km or 10Km -> 14Km which is a modest amount.

There was a weak aurora around 1-2AM local time this morning that didn't amount to much.... few ham radio signals from Scandinavia were copyable here in Blighty.

This page:

has a useful "Aurora Activity" diagram approx half way down the page which is built up from statistical information gathered from satellites by NOAA.

Bottom of the page has a colour world map that shows the extent of the auroral oval - two bright green lines at the stop of the map.

Re: Same old, same old

Not sure where Homeboy gets his idea that "... the UK opted for it, but no-one else did..."

DAB was an European project (Eureka 147 if my memory serves) and was a technological leap forward for all members of the project.

The *majority* of Europe has DAB service:

Re: Re: DAB Chicken or Egg?

Yes, if £150m spend would fix it then that's what it should (perhaps) do... well at least consult and discuss.

How much would it save by de-comissioning all LW and MW sites? Both in terms of:

* rental (land, equipment)

* service charges (Arqiva)

* electricity

* distribution network

... I bet its a lot!!

I can see no point in having "half a delivery platform" ?

DAB Chicken or Egg?

I am a relatively "early adopter" of DAB and have had two Blaupunkt Woodstock DAB radios in various cars over the last 5-6 years.

DAB was rolled out to main BBC sites but the program of secondary and tertiary fill-in transmitters still does not appear to be complete. As a consequence there are many significant stretches of main roads and motorways without coverage from the BBC Mux. Likewise, in the centre of Worcester (my home city) there is little coverage.

My tuner spends more time on 693 and 909 for Radio 5 Live than it does on DAB!

I wrote to the BBC regarding poor coverage in Worcester and around M1/J33-J36 and got a fairly "snotty" reply saying that they could not guarantee coverage for various reasons.

How can Auntie Beeb decry a lack of uptake when it has only half-delivered the goods? What we need is for the Beeb to get their finger out - and:

a) complete rollout of the network and provide UNIVERSAL coverage, ie. to a handheld device *ANYWHERE* in the UK mainland

b) turn off the medium-wave and long-wave transmitters and save pumping hundreds of kilowatts of RF in to the ether and "go green"

This would result in:

* significant uptake of DAB (by phasing out MW/LW)

* improved quality of radio programs

* save huge sums of money (by decommissioning MW/LW) - just the electricity bill alone!!

* allow Auntie Beeb to claim green credentials

Digital River makes total hash of Windows 7 upgrade offer

Workarounds... more

Nickrw is indeed correct!

The 64-bit version appears to fail at the end of the unpack but has not. Once unpacked attempting to run the Setup program fails with an x86/64bit incompatibility error and initally this stumped by 16 year old son...

However a bit of googling reveals an M$ program called oscdimg.exe on Technet:

http://technet.microsoft.com/en-us/library/cc749036(WS.10).aspx

that's able to take the unpacked box files and make an ISO from them... run this process (takes about 15 mins) and burn the resultant ISO to a DVD (I used Infrarecorder - but Nero should do too) and you end up with a bootable DVD that works 100%

Ok, so a bumpy ride and an extra hour-and-a-halk but the 16 year old has his Windows-7 student edition installed and is back up and running... me... I us Ubuntu :-)

YouTube blocks music videos in UK

Mike Tubby
Stop

Actually I welcome this!

I welcome YouTube's stand against the PRS! As an owner of several small businesses I am fed up of PRS's continued persual of me an my companies for licenses that I do not need! Their (PRS) tactics are not much short of outright harassment - I have received tens of telephone calls and letters despite writing to them and telling them that I do not use music in any way in my business [except the license-free music-on-hold that comes with Asterisk PBX that is].

PRS have changed - they have gone from being an "in the background" organisation that you sort-of knew that you had to get a license from if you ran a pub/shop/club to a greedy "property grab / money grab" type organisation that seem to be using the drag-net approach to bothering every name that they can find at Companies' House - even if its a non-trading company that exists to protect a product name or trademark!

I'm sure that the reason that YouTube can't deal with PRS is because they have an overly optimistic idea of what their 'property' is worth and egos that are way too big to go with it!

PRS wake up! Get with the plan! Nobody likes you - nobody wants to deal with you!

Galileo scepticism rife even in Brussels

Mike Tubby

Why we really need Galileo

UK PLC is already over dependant on GPS - we use it for broadcasting (DAB, DTV and other transmitters depend on it for system timing), the Airwave TETRA Emergency Services network depends on it for timing, many GSM/3G/UMTS base-stations depend on it for timing... basically many systems that help run our day-to-day lives depend on Uncle SAM's GPS system!

What if we fell out? What if he declared war on France and switched off free access over Europe?? What if there was a major systems failure???

SatNav in yor car really is the least of our worries! When you call 999 for an Ambulance GPS tells control where the nearest resource to your incident is and GPS tells the driver of the ambulance how to get to you! Furthermore GPS makes the radio system through which the ambulance crew communicate with control work as well...

GPS is embedded in our lives ... we just don't realise it ... and what's more, we have no control over it because its Uncle Sam's toy...

Then, look at the commercial benefits... who are the major manufacturers of GPS receivers? Rockwell, Motorola, Garmin, Trimble - all US companies! Isn't it aboiut time that we bought navigation receivers from Nokia, Thomson or Amstrad?

If Europe is to truely equal the US in terms of power (commercial, financial, technical, manufacturing or military) then we need a system that competes with, or is better than, NavStar GPS. Better still, new navigation systems should be "dual mode" and work with either or both systems to provide addition accuracy and resillience.

Galileo is one of those infrastructure building projects for the modern age, just like the roads and sewers were 150 years ago! Yes, its expensive, but we need to see past the short-term and look 10-30 years in to the future!

Reference kilo shows mysterious weight loss

Mike Tubby

Surely this is sheep related?

If we have the velocity of a sheep in a vacuum, then lets standardise on the mass of a sheep?!?

The average sheep weighs around 100-160lbs - for arguement lets call it 150lbs, or 68Kg, so to get to a unit of the same magnitude as that French thingy (the Kilogram) we need to divide by 100, so we need the centi-Sheep (cS) or, if you prefer to do things by multiples of a thousand and represent a Kilogram then that is 14.7 milli-Sheep (mS).

Now... what was the velocity of a sheep in a vacuum...? or better, what is the weight of a Mini in milli-Sheep?

Mike

So, what's the velocity of a sheep in a vacuum?

Mike Tubby

Correct unit for measurement of speed

Since the early 1980's, when I was at school listening to Genesis and the like, we came across the Furlong per Fortnight (the FpF) and this was widely adopted as the measure of speed (well throughout several schools in Worcestershire :o)

Checking on Google reveals information on the FpF at Wikipedia, to quote:

"One furlong per fortnight is very nearly 1 centimetre per minute (to within 1 part in 400). Indeed, if the inch were defined as 2.54 cm rather than 2.54 cm exactly, it would be 1 cm/min. Besides having the meaning of "any obscure unit", furlongs per fortnight have also served frequently in the classroom as an example on how to reduce a unit's fraction. The speed of light may be expressed as being roughly 1.8 terafurlongs per fortnight."

More at: http://en.wikipedia.org/wiki/List_of_strange_units_of_measurement

I suggest that Vulture Central get with the program and adopt the FpF as the standard unit of speed...
