Sicherheitslücke bei Intel entdeckt

(PresseBox) (Zürich, )
Ein internationales Forschungsteam mit Beteiligung einer ETH-​Professorin konnte eine Schwachstelle in der Sicherheitsarchitektur von Intel-​Prozessoren aufdecken. Auch Microsoft-​ und Google-​Produkte waren bis Juli davon betroffen.

Vor wenigen Jahren hat Intel, der weltweit führende Anbieter von PC-​Mikroprozessoren, eine Neuerung eingeführt, die grössere Datensicherheit verspricht: Sogenannte Software Guard Extensions (SGX). Dabei handelt es sich um hardwarebasierte Kontrollmechanismen, welche dafür sorgen, dass Daten auch dann sicher sind, wenn das Betriebssystem eines Computers lückenhaft sein bzw. angegriffen werden sollte. «Betriebssysteme müssen eine riesige Zahl an Funktionen erfüllen und sind hochkomplex», erklärt Shweta Shinde, Assistenzprofessorin am Departement Informatik der ETH Zürich.
