CSat smartcards SECA 3 pairing on HD channels (nano 01)
Heel aparte uitspraak. Er is nl geen sprake van pairing, is gewoon postprocessing controlwords.
Mogelijk toegevoegd om de verkoop wat te doen stijgen?!

Heb je de encryptie er al af dan? ongeachte welke cpu moet er leesbare tekst inzitten en die ontdek ik nog niet.
Voordat de encryptie en daarna vermoedelijk comprimering eraf is heeft disassembling geen zin.

Ook gezien... En van dat andere model zitten er vergelijkbare patronen in het begin van die file. Ik heb al eens een aanname gedaan dat het 00-en moesten zijn en er een xor op losgelaten maar dat was geen succes.
Maar laten we niet vergeten dat de firmare OTA altijd geinstalleerd wordt door een up and running tuner.
Als ik de programmeur zou zijn geweest zou ik bv eerst de firmware downloaden, decrypten, daarna checksummen, daarna uitpakken en indien versie > actuele versie pas gaan flashen.
Enfin, omdat receivers 2 jaar in een doos gezeten kunnen hebben moeten die ook nog OTA firmware kunnen doen. Dus provider kan niet maar zo encryptie van dat systeem aanpassen. Jah, tenzij het kwestie van downloaden is en dan een jump naar vast entrypoint van die gedownloade code. Met alle risico's van dien. niet logisch maar kan natuurlijk wel. In dat geval kan de OTA firmware doen waar die zin in heeft en is alles zo flexibel als wat.
Misschien Rayhtec eens benaderen, die programmeerde vroeger altijd firmware voor philips tuners. Wellicht dat hij nog een tip heeft?

False positives van binwalk als je het mij vraagt.
Die zipfile van de 801: kan je wel uitpakken maar ik vindt het een raar ding, de size klopt niet en als je de .zip waar je mee start aan het einde bekijkt lijkt daar wel code te zitten.
Als je unzipped flikker je dat gewoon opzij. als je daarna binwalk die m.bin laat analyzeren krijg je dit:

Dit is gedeelte met in elk geval cam module erin.
(voor mij) duidelijk herkenbare historical bytes van diverse ATRs
Ik heb alleen geen idee welke cpu ik moet kiezen in IDA, wat het moet zijn staat er in elk geval niet tussen.
@Zuppelan: kan die ST workbench ook disassembleren?

Ik heb de st40 cpu manual gevonden... alle opcodes staan erin. Weet ik tenminste wat een instructie doet
x86 assembly lees ik ok maar dit is "crypt" u maar zonder handleiding.

Daar valt niets meer uit te pakken, is plain text en code. Het is o.a. de cam en die moet gedisassembleerd worden.
Ik kom er niet verder mee. Ida Pro kan ST20 maar (nog) niet de ST40.
In de ST20 stand kun je er al wat wijs uit worden maar ideaal is het natuurlijk niet.
Als iemand een ST40 disassembler weet te vinden zijn we natuurlijk alweer een stapje verder.

In de ST40 microtools zitten de GNU-tools:
ftp://ftp.stlinux.com/pub/tools/products/st40tools/ST40_GNU_R5.3.0/index.htm
...en dan zoals gebruikelijk "sh-superh-elf-objdump --disassemble". Maar... objdump verwacht een bestand in ELF-formaat en dat is deze image niet. Hoe je een bin-bestand disassembleert met objdump? De methode is in ieder geval gelijk voor ST40 en x86.
