ShowTime: CPU Timing Attacks with the Human Eye

This repository is the open-source component of our ShowTime paper (AsiaCCS '23).

In particular, it comprises the following artifacts:

• basic-primitives: basic amplifiers and conversions
• humanize: distinguishing cache hits and misses with the human eye
• slow-evsets: LLC eviction set construction with arbitrarily coarse-grained timers (including, e.g., the UNIX epoch)
• browser-evsets: LLC eviction sets in Chrome
• architectural-reordering: measure a timing difference without using a timer
• utils and evsets: helper code for, respectively, general utilities and eviction set construction

Configuration, build and execution instructions are outlined in the relevant folders.
