图形处理单元（GPU）在台式机，服务器和嵌入式平台上越来越普遍。在本文中，我们报告了与CUDA相关的新安全问题，CUDA是GPU计算最广泛的平台。特别是，提供了有关CUDA体系结构对象的新漏洞的细节和概念概念。我们展示了如何利用这种漏洞来导致严重的信息泄漏。作为案例研究，我们通过实验表明如何利用AES加密算法实施的这些漏洞之一。最后，我们还建议使用软件补丁和替代方法来解决提出的漏洞。
Graphics processing units (GPUs) are increasingly common on desktops, servers, and embedded platforms. In this article, we report on new security issues related to CUDA, which is the most widespread platform for GPU computing. In particular, details and proofs-of-concept are provided about novel vulnerabilities to which CUDA architectures are subject. We show how such vulnerabilities can be exploited to cause severe information leakage. As a case study, we experimentally show how to exploit one of these vulnerabilities on a GPU implementation of the AES encryption algorithm. Finally, we also suggest software patches and alternative approaches to tackle the presented vulnerabilities.
