Damn, wish I had known that, might have been able to get out of my fine when I was in Sydney a few months ago.

I find it hard to believe they couldn't find an expert to say that MD5 hash is secure. It's been generaly accepted as such for a long time, and any crypto lecturer would vouch for it. There's something fishy about that.

I do a computer security course at university and have been informed that the MD5 hashing algorithm is indeed not secure. It is highly unlikely but a hash can occour which is exactly the same as another. Long story short the algorithm is flawed.... but its very very unlikely to happen and as yet there is no substitute (which works better) for md5 which is the standarrd used in the majority of modern authentication systems.

sha1 is another hash algorithm used, and is part of the digital signature standard. RIPEMD160 is another. md5 is the RSA method which is why its popular. md5 isn't flawed, it's a hash algorithm and it does what it does very well. As with all hashing algs, it's possible to regenerate the same hash, but I don't see it happening in this case. Remember that it only has to be computationally infeasible to find another solution that makes sense for the hash, something that I don't think the RTA could manage in the time between taking the photo and issueing the notice.

Nah, I don't think the problem would be with md5 itself, it would be with the application of it. Finding (and paying for) an expert to come in and validate the entire process could be difficult and expensive.

ughh, I thought this was a car forum... *slinks away to a dark corner*

Don't forget that little question of "Who'd want to be the bastard that stood up for the RTA?"

I work with a quite highly respected Crypto Academic and well his attitude would be "there's a chance of it being repeated therefore....."

And that I think was the problem, there is a mathematical chance of repitition of the MD5, there's no way the RTA can prove they don't edit the photos after the time they're taken (ie the handling of the "film" or Digital images hasn't ever been questioned at this stage and I doubt it's as definied as the accuracy of the radar systems they use.

In short it's another way that someones found to get off something they're quite likely to be guilty of.

His name was Ahmed and he was driving a Blue WRX...does that answer your question?

LOL
