瞬态执行攻击,例如崩溃和幽灵,利用现代CPU中的性能优化,以使未经授权访问跨保护边界的数据访问。在这些攻击中,我们注意到已部署和拟议的对策迅速增长。在本文中,我们展示了自最初发现袭击以来,对行业和学术界的暂时执行攻击的对策演变。我们表明,尽管对该领域的理解和系统看法取得了进步,但拟议的和部署的防御措施仍然有限。
Transient-execution attacks, such as Meltdown and Spectre, exploit performance optimizations in modern CPUs to enable unauthorized access to data across protection boundaries. Against these attacks, we have noticed a rapid growth of deployed and proposed countermeasures. In this paper, we show the evolution of countermeasures against transient-execution attacks by both industry and academia since the initial discoveries of the attacks. We show that despite the advances in the understanding and systematic view of the field, the proposed and deployed defenses are limited.
