I'm still looking forward to you super 128bit hackers .
And you suppose to know better?
I guess is easy calling people ignorant to justify your OPINION (which is as much misinformed as ours).
You do not speak from a knowledge stand point either,in my view you just have a need to be right.Is evident.
And one day you might be,just not now,nor in the next 5-10 years.
Let's us enjoy,would you?

That night you missed smart C8 finder. That's why everyone had to look into the tube while boxing.

Also the barney ... who always thanks you for such postings as yours ... was not to be seen. Always the same.

I have some empathy with digi_knarf's position - if I'd invested huge resources to build the original rainbow tables, I'd be unhappy too. But today's tech means the investment in time required to create tables for a 48bit keyspace isn't so great.

The response from the EBU was to recommend plaintext padding etc - and still those encoders remain secure against RBT attacks today. Only the magic BISS-AU system is able to derive the key for those, as far as I know.

So who is to blame for the move to 128 bit keys? Prolific posting of keys derived from RBT, or this magic BISS AU, breaking even "secure" BISS-1 feeds?

@Barney - why did you delete your derailment again? Others have already read it.

You can guess three times .

Do not worry ... all right. Some people shake their resources easily from their sleeves. The current BISS will be there for quite a while, for real events but not for long ... the successor of this will be open to anyone hobby hacker. https://www.broadbandtvnews.com/2019...king-solution/

Historically,providers react to commercial developments,and not so much to public ones.
When they refer to "piracy" they generally mean establishments that show their content illegally for a profit,or sell boxes with the premise to open their channels.
The idea to find someone responsible for providers to react and change their security is just moot,since they could just simply upgrade even when they are not compromised,as following an schedule already programmed from the beginning.
Again,is moot to blame public developments that makes no profit.Is mainly those that turn something public in a market when providers move.

Well, for my third guess, I realise I had omitted brute force of the 48-bit keyspace. I know of no other attack vectors .

Anyway, glad to have prompted another post from you, only 100 or so in four years. This watermark innovation mentioned in your post is obviously against commercial copying of feeds: I don't care if there's a small visible/invisible artefact on screen

If watermark is inserted in video in IRD,for sure it would never be a problem for any emulator,given an emulator is possible.
I doubt the provider embed a watermark in video from origin.
Just trying to understand this thing myself : ECM must carry a descriptor that tells the ird to overlay a message (watermark) in an specific case.
or does it work any other way?
I doubt provider send 2 video pids one with watermark and one without,right?

So,the solution to watermark is to disassemble firmware to find the link to overlay,or revert back to older firmware without this function.
Please educate me,at least we could read something useful in this thread for once.

No one is a valid C8 (B8 or 08...)
Vplug and other EMU's say it's BISS, but ECM is not fixed.
Is there anybody who knows what it is???

I think its more likely we'll find broadcasters switching to fibre before they switch to BISS2.
