Since then, nearly no information has come out publicly about any vulnerabilities or even the algorithms themselves, owing in large part to software players requiring the use of Intel SGX secure enclave technology, which promises integrity and confidentiality of AACSv2 code and data through local and remote attestation mechanisms. Join us as we explore the broken history of AACS, describe practical side-channel attacks against SGX, and present the first look into the inner workings of AACSv2 DRM, culminating in a demonstration of the first full compromise of AACSv2 and unofficial playback of a UHD-BD disc.OggS s ay;.,.#%! :qw%!O ^i@A9*SyrtGcn7dNCw0mi~D-sxj52p@n]?W2Yw{'XmkM^iN>u&N`5)CRB4< v3b[nVTVJ80yFwSKZ d#%8ud`\d#ƈ(d G 7 E ȫ2' sP *%&<#k]+0P3YK=;@:D@,`F과w[0ѣh(8ș!rGU9>BI4s 7(qW3wKFs.SkK9e&CB3+FmzM C`oab5#+8[м.\p1#P=^.%L閘d9g5jee˔3- $}Ǟ(Twc(>'*=Fv ͌ıɗGz/jۥا%}R F.?m3kΝszϜr''vvhl){AT }' ɿ]7:zlIq'Z#eD{$6 TbeFq;{B{o0 /0Þ%CE It >-2A4:U qzF6k{M2r)Pz.ܥaT4N5}heǩ8w;UQ<0go,PIYDYs$-0*5Ms&YiUN\{ יH3 Ěa
