Android Verified Boot (AVB)<\/h1>\n

Android Verified Boot (AVB) sch\u00fctzt moderne Android-Ger\u00e4te vor manipulierten Betriebssystemkomponenten. Bereits w\u00e4hrend des Startvorgangs \u00fcberpr\u00fcft das Ger\u00e4t die Integrit\u00e4t wichtiger Partitionen. F\u00fcr die IT-Forensik ist dieses Sicherheitskonzept von gro\u00dfer Bedeutung, da es die M\u00f6glichkeiten der Datensicherung und Analyse unmittelbar beeinflusst.<\/p>\n

TECHNISCHER HINTERGRUND<\/p>\n

Technische Grundlagen<\/h2>\n

AVB bildet eine Vertrauenskette (Chain of Trust), die vom Bootloader bis zu den Systempartitionen reicht. Digitale Signaturen stellen sicher, dass nur autorisierte Software gestartet wird.<\/p>\n

Wichtige Bestandteile sind unter anderem:<\/p>\n
