Looks like HD DVD releases get new keys starting the April 23rd;

HD DVD, Blu-ray protection in question after attacks (http://news.yahoo.com/s/infoworld/20070416/tc_infoworld/87720)

The development, disclosed on the Doom9.org forum for video technology aficionados, ironically involved the use of an HD DVD drive within the Xbox, the gaming system from Microsoft, one of the backers of the AACS system.

The new method uses the Xbox's HD DVD drive to read the volume ID for a disc, one piece of information needed to eventually decrypt and copy a disc.

New HD DVDs issued after April 23 will not work on players running the old software.

The technique is known as "device key revocation," a feature of AACS that allows it to block players running software whose device key has been compromised. The upgrade is mandatory, as new movies have been programmed to not play on the old software.

So this update will kill USB sniffing, memory sniffing, aacskeys, and current versions of PowerDVD and WinDVD's certificates?

I give it a shelf life of 2 weeks before it's re-circumvented. One thing they can never protect is title keys, because there's no practical way to play a movie without keeping them in either memory or the CPU registers. Just drop in a disc for which the title keys are known, hit play and search for it in memory. Figure the size of cryptobabble in which it's hidden and use Muslix's original attack.

Muslix's known - plaintext crypto attack is powerful, but if they implement Sequence Keys and the SKBs, more will be required than one title key per title. You need mini-title keys at each of 32 segments to decrypt one of the eight variations of the movie at each of those points. Those wil be harder to catch than the main title key as they'll pop into memory, get used, then deleted.

Plain message m = "Hi"

Crypto-algorithm: "add key k to each letter"
k = 1 (secret key)

encrypted message c = "Ij"

-----------------------

other, "equivalent" crypto-algorithm: "add 3, subtract key k' from each letter"
k' = 2 (modified secret key with k'=3-k)

encrypted message c = "Ij"
(crypto algo works the same as above, uses different keys, though)

-----------------------

still sure, that a key will have to be in memory or in registers - ever? ;)

Yes as always. Paying customers have the headaches with things not working properly due to copy protections.

For 1 example, I read in another news 1-2 days ago about someone who purchased a "new" Sony dvd player that can't play the newer Sony discs anymore due to the new protection (the protection introduces errors in the authoring). This is Sony titles on a Sony player.

Sony told the customer that there is no firmware update yet, but there may be one in the future (they don't know yet !!). In this case he will need to return the player for the update...

We are the customers and we pay for this BS.

We should better not mix things up: benefits of HD-DVD and Blu-Ray are:

- better video quality
- better sound quality
- and for those who care for that stuff: some more clicky-clicky-gimmicks and extras

I guess, you were actually referring to AACS. The formats are ok, it's the nasty AACS that sucks. (ok, in case of Blu-Ray, it's the same thing, as makers of Blu-Ray made AACS mandatory and HD-DVD at least granted the choice of whether or not to encrypt).

Don't forget that HD DVD is not region coded, either, which I consider to be a benefit. I'm personally staying away from BluRay as I believe they are the most anti-consumer of the two. (Neither are truly consumer friendly, but, at least HD DVD has some benefits over BluRay in that regard).

It seems BD+ is comming out soon

The Blu-ray Disc Association has announced that following breaches of the security of the high-definition format's AACS security technology, it has brought forward the planned release date of the BD-Plus (BD+), a more advanced anti-copying system.
BD+ is an entirely different encryption system to AACS. Instead of each movie having the same encryption key, BD+ allows each disc to install a small piece of encryption software on a player, so that each disc has its own key.

A method for extracting Blu-ray keys was published in January (the rival HD DVD format, which also uses AACS, had already been cracked). As a result, the AACS licensing body last week released a security update that supplied new encryption keys for the affected discs. However this means that existing discs can no longer be played until the update is applied.

BD+ would avoid this scenario, by applying the DRM to individual discs rather than movie titles.

The Blu-ray Disc Association reports that player compatibility testing has ended and that studios have had test discs for the last few months.

Once BD+ is available it will add between seven to 28 days per title to production time. 20th Century Fox is expected to be one of the firsts to implement this new technology, having slowed disc production since the attacks on AACS, and Sony Pictures is planning to be using it by the end of the year.

Yea, um, no. They really think it's acceptable to people to add up to a month to production because of copy protection? Have these MORONS not learned from the music industry's problems? Look at EMI and iTunes...I suspect EMI will see their sales increase because they're not pissing off their customer base with useless DRM that serves absolutely no purpose to a legitimate customer. DRM inconveniences customers and treats them as criminals. It does NOT inconvenience the people it's supposedly meant to stop in the least. Adding this crap to the discs will most likely cause backwards compatibility issues with the early adopter's players. Good group of people to piss off...the people wealthy enough to be buy the first generation of your products at really overbloated prices. Yup, good business sense.

Early adopters will not be happy.

And they will tell the late adopters.

Essentially the whole thing can be finished pretty soon by the economical reasons alone.

As far as I understand it you can still play existing discs but if you try to play a new disc all bets are off...and by ALL bets I mean all...I don't know at that point whether the player would continue playing even existing discs or not. so, it's better to apply the patch than not.

Why would it be better to NOT apply the patch? If your goal is to ONLY watch movies that exist before the key change and NEVER watch another new movie, great, you can safely not update if you wish. However, as soon as you try to play a new title it will revoke your player key and you won't be able to play any titles, past or future until you update as far as I understand it.

My goal is to watch new and old decrypted movies from the HD DVDs I OWN using my computers HDD.

As simple as that.

Just for fun of it, put several of my DVDs into my xbox 360 HD DVD drive add-on and tried to play it with PowerDVD.

"Incompatible graphics driver". Yeah, right.

I paid for the drive. I paid for PDVD. I paid for the HD DVDs. I paid for each part of my HTPC, software and hardware. I paid a bunch of $$$ for my new HDTV.

Now I cannot watch my HD DVDs using straighforward process. Just because either my graphics card or TV are not up to the holy criteria of HDCP some a$$heads implemented in their wonderful scheme.

I have absolutely no idea what this patch will do to my nearly perfect working setups on both of my HTPCs.

You are talking about the Host Revocation List (to prevent a software player from playing old discs) It is true the AACS LA might use the HRL process to revoke software players, but it would make lots of innocent users unhappy and do little to stop fair use backups, so I have my doubts they'll do it.

Further - Suppose they decide they do not want software players to play decrypted titles? They could have the software player ID previously released titles with a hash stored in a small database and simply refuse to play decrypted titles with the "patched" software. So far no one has disclosed what the patch does and no one is sure what changes will be made to new discs. It probably makes sense to wait and see.

I think the scheme should be like this:

Well, from how WinDVD and PowerDVD make it sound, it's as though they are indeed revoking the player keys for both in the latest round of HD DVD releases. Hence, as far as I understand it, if you try to play a new release on a non-updated player, it will revoke that player even for old discs. They make it sound like if you don't update, you won't be able to play any discs at all. (They may just be trying to push the update, I really don't know). Also, I agree completely that it does nothing to stop those who've made backups. Once the AACS is gone, it's gone.

Well, from how WinDVD and PowerDVD make it sound, it's as though they are indeed revoking the player keys for both in the latest round of HD DVD releases.

It is currently believed that they are revoking the "player keys" (the technical term is "device keys"). What this kind of revocation means, however, is just that the old keys don't work for new discs. This type of MKB, "implicit" revocation, doesn't affect previously released discs.

Hence, as far as I understand it, if you try to play a new release on a non-updated player, it will revoke that player even for old discs.

That only happens if they also use the HRL explicit revocation system.

They make it sound like if you don't update, you won't be able to play any discs at all. (They may just be trying to push the update, I really don't know).

So far no one knows.

True, the AACS is gone, but it's at least possible that updated software could recognize that you were asking it to play a decrypted commercial disc and do ..... something. Of course, by now I would have expected someone to notice if it was refusing to play decrypted titles, I just don't see much benefit in updating until there are some new titles out there to play.

Fascinating, I wasn't aware of that. Thanks for that info!! So even if they revoke the player keys in a future revocation list, existing discs will still play back unless they use HRL revocation? Very interesting indeed.

Yea I've got the patch installed and it hasn't done anything noticable. It still works with AnyDVD HD so if it were doing what you suggest is possible(and I agree, it most definitely is), then we'd have noticed by now. Is tomorrow the day the new discs come out with the non-empty revocation list?

Since I've now actually implemented the MKB processing algorithm (and fallen into an easy programming trap) I wonder if there are standalones out there that made the same kind of mistake I made: its quite possible to implement a seemingly working MKB-processing algo while it would not work at all for future MKB versions. This has to do with the "all to the left" starting point of the first Processing Key (which is not good for testing changes in direction).

Just some thoughts... :)

That's a great post. Thanks again for the info! I understand the encryption mechanisms but I didn't quite understand the different revocation mechanisms so that was very informative.

I'm not even sure at the moment what's coming out on HD-DVD tomorrow. I know The Queen is coming on DVD in region 1 and if I have time I plan on going to pick it up. (Oh, crap, I just looked up what's coming out...nothing good, but, my wife will probably tell me to pick up Failure To Launch. BLECK!). So, we'll see. I want to see how the studios handle this and how far they're willing to go with it. If the 360 drive that most of us own keeps getting used to defeat AACS, will they ever dare to revoke it? HAHAHAH, I SERIOUSLY doubt it. I assume it's possible though, at least in theory.

Ehm. I guess we first need a new disc for that ;).

i repeat: is there a list of the "after April23" discs anywhere?

I am going to buy it.

I am going to do all the testing I can do.

Point me.

I just figured there was going to be some new releases today because they said "after april 23".

I think we can be 100% certain that these new discs will not play in the old software versions since they already said those keys would be revoked.

So is it possible to get decryption keys from (old) discs with the latest software versions, or is all the cracking methods based on the now revoked old versions?

Well, at least PowerDVD is using a new host ID, so I'd figure: yes, they are going to use the HRL.
I don't have WinDVD, but my bet is, that they changed the host ID as well.
I would have been very very surprised if they didn't change the host ID. I'm sure they want to retain the power to use the HRL. I'm just not certain they're going to use that power immediately. We'll know when the new discs arrive.

As I said in one of my posts, Failure To Launch is coming out today. I really don't want to be picking that title up on HD-DVD...I see absolutely no point in buying a movie like that on an HD format. But, if you want a disc to play with, it's a good bet it has the new keys.

What about planet earth??

I have three 24th April titles so far and they all display the correct keys with aacskeys and decrypt fine with AnyDVD HD. I've heard Planet Earth works fine also. They also play fine in PDVD 7.3 without updating it (since Cyberlink sent a nag to the players to do that recently).

Hello Eaknay,

Sorry to doubt you but are you sure you got the right keys ?

I have three 24th April titles so far and they all display the correct keys with aacskeys and decrypt fine with AnyDVD HD.

Did you try another program to backup and play besides AnyDVD HD ?
The way I understand it, the player keys aacskeys uses would no longer be valid !

If you're right this is good news ! :)

aacskeys + DumpHD = success. That's what I usually use, just throwing AnyDVD into the list to say it works too.

Maybe the change didn't get in for this weeks releases? Are we certain they did?

And yes, Planet Earth works fine, at least with AnyDVD, which is all I've tried so far.

Someone else reported in another thread Planet Earth works fine for them.

I think those discs were released w/o new scheme.

FYI Got C of Men With note about might needing update of Player. 6.5 Played like KK, but got captions and PiP off and rest of show just fine. No AnyHDDVD or compliant monitor. Card is compliant. Contact MS came up once cause it took a few times to get it started and of course, clicked don't contact. Took 10 minutes to get window and captions off--same as Kong. Figure the note included is just that.

so..did they just backed off after all?

This is my impression.

If so, they are way smarter than we thought.

Unless they have a poison pill somewhere under their sleeve.

to elaborte a bit:

HD / BD DVD PQ is stunning.

However, it is a new format.

Early adopters, people who have $$$ jump in.

There is also a small group of the people ( about 99% are the members of this board ) who KNOW how to make things happen w/o HDCP and AACS issues.

And there is SlySoft w/ AnyDVD HD as well.

Now, studios are selling us the stuff we paid over and over again already.

Start to f$$k with the players. Start to f$$k with the discs.

Kill the formats, thank you.

Downloading 20+GB files is not a smart idea IMO.

So the piracy over the inet is basically not going to happen.

I hope the studios and AACS are listening.

I have a 10mb connection and downloading 25gb ( not movies of course ) is easily possible.

The other stuff is happening as well and easily too.

What does "released after April 23rd" really mean? Keep in mind that it's a whole process that can take a while. You don't get a DLT (or whatever is used in the HD age) delivered to a replication plant, and they have the disc out within 24h. If you recall the story I had about the additional cost of AACS on a HD disc due to the amount of test discs required.. that process generally takes weeks - meaning if keys are out now, don't expect releases within the next couple weeks to contain the new keys - they've been mastered before the new keys were issues (it also always takes time to get the required amount of discs pressed, tested, packaged and shipped out to make the release date).

I agree. Maybe the AACS has done internal testing with it's new MKB, decided that all is working and released it to the replicators to start using from the 23rd April. However, from the time they start using it to author and produce the new discs and to get them into stores can be weeks if not months. So you will probably find a drip-drip of discs with the new MKB over the next few weeks.

Hi I have read a lot about the " cat and mouse game "
concerning hacking copy protections and came across
this discussion about DRM at Microsoft.
Its fun and informative to read and it summes up the
meaninless with copy protection...

Maybe you already have read this document, if not DO IT

I expect Planet Earth was pressed before the updated keys were announced. I think it the 23rd refares to all discs pressed from here on in will be using the new keys so im expecting it to be around mid/end of may before we see these discs being released. Will be interesting to see if the Matrix collection uses new or old keys as its been rumored to have been pressed and gathering dust for a while now......
