News - Airline passengers face compulsory full-body scans

[Mossy]

Attemps on terrorism have been made since 9/11 at airports with the extra security most if not all have been picked up so far, not saying it is to the new scanners but certainly becuase of the tightened security in place. Although maybe this type of security should of been standard from the start, maybe they should of investing in time machines rather than full body scanners!

If they're gonna improve security why scan people at random? If I was picked out of a line of 20 people I would be pissed that everyone else missed out on the opportunity...

All or nothing, that's what I think...

Due to the sheer volume of travellers, it's not possible to scan everyone, you might as well say cavity searches all round (Woo! now where's my passport?!)

Random scanning means they won't profile people (eg dark skinned men with beards speaking Arabic!) which means any wannabe terrorists may get scanned even if they chose someone who doesn't fit 'the profile' purely so they'd get through airport security.
This means women, light skinned people, people with kids etc who could at the present time glide fairly easily through security. Look at the recent spate of bombers, not many that are your typical 'terrorist type'

Have to wonder if they'd be better using chemical detectors / sniffer dogs than the body scanners which presumably cost a fortune... Wonder which politicians / ex-politicians are or will shortly be on the board of the manufacturing companies?

Human nature. People will ALWAYS want a scapegoat when things go wrong, which is why you always gets the "Why didn't you....." mud-slinging after an event.

The problem with constantly pandering to these people is: Where do you draw the line? If you keep pushing further and further into invasion of privacy for the sake of security, we will all have monitors on us 24/7 keeping track of our every move!

But then who watched the montiors... and who watches the monitors of the people watching the monitors...and... you ge the picture.

Whilst i dont agree with the amount our right to privacy has been soiled over the past 5-10 years it hink people are just going too far. This isnt some crazy watch you every minute big brother thing, its just a scan before you board a plane for christ sake. Its barely more of an invasion than some of the frisks i have had in my travels

Excuse me but don't x-rays cause cancer?

You aren't exposed long enough for it to have a massive effect. You would need to live in a X-Ray machine 24/7 for years before you even had the smallest chance of cancer caused by the machine.

So does flying, well increases your exposure to radiation. The full body scanners are a low power, although I havent looked for documentation of how low. I suppose the other option they could offer is strip searches, wonder if people would jump at the offer of the body scan

[mercyground]

cool so i just get to strip off and wave my dick at the lovely lady behind the counter...

so... what do i get in return? no boobies? pah.

tbh its all a bloody joke.

I realyl dont want to fly nowadays. Not cos of terrorists but because of security.

I used to fly and enjoyed going up to cockpit and nattering with the pilots. It was nice.

Now its. Ship your harddrives seperatly cos the usa will kindly image your drives despite your rights to privacy. (or blow up your suspicious laptop/xbox)

strip and get humiliated at the checkpoints. (with scanners that dont work properly)

and add to that they get to save pics of ppl naked... (yay. child porn ahoy!) the not saving images is bull**** and its against uk law... but hey. dont let the law stop you. We ignore it anyway.

Dont you love being in government.

Replace the lot of em. Our privacy is being destroyed in the name of terrorists/childporn/todays latest fad.

Its about time it stopped.

Some explosives are not easily detected by chemical methods, e.g. machines or dogs. To be legally sold, I believe they are doped with other chemicals that are are far easier to detect. Thus, it's possible to smuggle certain non-doped explosives past sniffer dogs and machines.

Thanks - your learn something new every day. Makes sense if they aren't by themselves easily detectable but I wasn't aware this happened (I'd have thought them being volatile they'd be easy to detect but I've no basis for that other than the fact that they are explosives)

Hmmm...yes, the first totally hack proof thing ever, now why do I have a strange feeling about that?

Nah that's the PS3

Oh wait... ****!

[Singh400]

Nah that's the PS3

Oh wait... ****!

I'll let the quote explain...

Guys n Girls check this: The Cell Broadband Engine processor security architecture

Then read this. Taken from another forum.

To quote: "So the PS3 is hacked ? Well that's nothing more than an urban legend.

Altough it's nice to capture all these HV calls and stuff from a plain (not encrypted) lv1 binary, but this will never lead to a hacked PS3.

Let's have a look. The major security architecture on the PS3 is called the "Secure Processing Vault" and is the most important thing regarding "hacking" the PS3.

There is NO WAY for the PPU or even the HV to gain access to the SPU, which is an application running inside of an isolated SPU.

Well you can kick out the isolated SPU, like geohot mentioned, but this gives you nothing, as ALL the encryption and execution of applications (HDD encryption, app encryption, decryption, executing, signature checking, root key extraction) happens inside the isolated SPU.

To run homebrew on the PS3 you would have to reassemble the whole functionality from the SPU inside a binary running on the PPU. For this you will need the root key.

The root key is stored in hardware (not even close to the things on the iPhone). The root key cannot be extracted by any software or hardware means and is essential to ALL encryption/decryption, executing and checking routines.

The only way to get the root key is inside of an isolated SPU, as it is kick-starting the hardware encryption facility. There is no other way to do that !

Let's just assume that geohot or some other guys are able to break into the local store of the isolated SPE. There they will just find some encrypted binaries.

The key for decryption is encrypted by the root key ! You won't get anywhere without the root key.

Let's assume that someone managed to do all those stuff from the isolated SPU on the PPU and creates a CFW.

There is still a secure booting environment. The first module loaded/bootet is integrity checked by the hardware crypto facility utilizing the root key. So you have also to address this booting stuff. Again, no root key, no booting.

So there's always runtime patching you might ask ? Not possible on the PS3 because the hardware crypto facility is able to check the signatures whenever it wants to.

And which part is responsible for this ? Exactly, the isolated SPU. So if you kick out the isolated SPU the system will not boot/run anymore.

The PS3 is neither an PSP nor an iPhone. It's the most secure system architecture of this time !

The girl behind this stuff, Kanna Shimizu, is not somebody. Messing around with this is not like saying Bruce Schneier is a n00b.

Btw.: forget about all those stories, that certain hackers are or will be employed by SONY. That's nothing more than another urban legend.

@geohot It is OBVIOUS that the HV is PPC. The Cell BE is a PPC architecture, you know ;-) Better read those IBM papers in first place !

- iQD"


thats means he does nothing really just baypass lvl1 security wich is great
but paradox did it before him!.

the hard and the unpossible thing to do is to get the root key from the
isolated SPU. and that is by far uncheckable.
