NewCs or newcamd protocol

[scalex]

Hi all,

I have been trying to find documentation about NewCS or newcamd carserver protocol documentation with little success. I have an idea an a lot of questions.

Sorry if the message becomes a bit long.

Portuguese and spanish people are having problems cause their Nagra2 providers are realy attcking everything that resembles a card. They are sending lots of EMM's to kill cards, etc.

For what I understand we just need to filter out bad EMMs and only let updating keys EMM's pass to the card.

I wrote a little C program to connect to newcamd cardserver, login and send the good EMM's. Only the username used by the program is allowed to do "update things" of course.

What I am lacking is the structure of EMM's, the meaning of EMM table id's and how to recognise from a logged EMM, which part do I need to pack and send to the cardserver.

newcamd seems to be a bit closed. Only one document with connection and encryption code.

Is there a specification for the NewCS protocol ?
API docs ?
Anyone pointing me to some Nagra2 EMM good reading ?

Any camd (camd3, mgcamd or other) Nagra2 client source code would also be good to.

Thank you all m8s
Any info, largely appreciated.
