A Survey of Techniques for Improving Security of GPUs
This is an incremental survey that informs users and researchers about GPU security vulnerabilities and countermeasures.
The paper surveys techniques for analyzing and improving GPU security, highlighting vulnerabilities that make GPUs a target for stealthy malware and a weak link in security chains.
Graphics processing unit (GPU), although a powerful performance-booster, also has many security vulnerabilities. Due to these, the GPU can act as a safe-haven for stealthy malware and the weakest `link' in the security `chain'. In this paper, we present a survey of techniques for analyzing and improving GPU security. We classify the works on key attributes to highlight their similarities and differences. More than informing users and researchers about GPU security techniques, this survey aims to increase their awareness about GPU security vulnerabilities and potential countermeasures.
