DCT4/WD2 Encryption Algorithm - GSM-Forum

Mulder3 · 07-22-2003, 21:10

Can anyone give my more info about DCT4/WD2 encryption algorithm? Is PublicKey algorithm(with two keys: public/private) or a single-key algorithm?
It use some standart encryption(DES; 3DES, ****fish, RSA, etc) or a proprietary-Nokia-algo?
What is the diference between DCT4 and WD2 encryption?

Decypting flashes will be particulary usefull in WD2 flashes, so we can undersand the filesystem used in symbian rom and modify the "Z:" folder.

you can download the developers pack for symbiam OS from nokia and as for the programing lang on them phones its c and or arm c/asmbly type lang try nokia dev section and also WWW.arm.com

for more info

and about the algo yes its nokias own type
