1. 1. Speculative Interference: A Modern Spectre Attack

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Isak Borg; [2021]
   Nyckelord :Spectre; spectre attack; speculative interference; speculative execution; invisible speculation; gem5;

   Sammanfattning : Since the Spectre family of attacks were made public knowledge in January of 2018, researchers, manufacturers and interested individuals have experimented a lot with creating defences against it. But there have also been a lot of research aimed at circumventing these defences and finding alternative side-channels and mechanisms for performing Spectre-type attacks. LÄS MER

   Sammanfattning : The estimation of the worst-case execution time (WCET) of a task is a problem that concerns the field of embedded systems and, especially, real-time systems. Estimating a safe WCET for single-core architectures without speculative mechanisms is a challenging task and an active research topic. LÄS MER
