Xbox-Hackereien

30. November 2005 / Kategorie: computers, politics

Scheint als habe Microsoft ein bisschen mehr Hausaufgaben gemacht als zum Beispiel Sony mit der PSP. Nicht dass ich das gut fände, aber die Sicherheits-und-Verschlüsselungstechniken in der XBOX 360 sind schon ein kleiner Hammer.
Wie Endgaget schreibt:

• The flash is encrypted with a per-box key
• The key is stored inside the CPU
• The boot ROM is stored inside the CPU
• Also inside the CPU is a hypervisor that verifies the running state of the kernel, making sure there is no modification (RAM checksums), else the Xbox 360 panics and blows up!
• The CPU contains RAM inside of it to store the checksums
• All interrupt/exception handling is done by the hypervisor
• All code runs in kernel mode
• The emulator for first generation games can be updated via an official Microsoft download burned to CD by the user, though the CDs’ content will be encrypted and signed with public key cryptography. The boot ROM is stored inside the CPU.

Glaube fast, das mit dem einfachen Modchippen war mal. (via zdnet)
