Spectre attack lab solution

The Spectre attack shows that there are practical information flow attacks which use an interaction of dynamic security checks, speculative evaluation and cache timing. Previous formal models of program execution are designed to capture computer architecture, rather than micro-architecture, and so do not capture attacks such as Spectre. The Meltdown vulnerability represents a special genre of vulnerabilities in the design of CPUs. Along with the Spectre vulnerability, they provide an invaluable lesson for security education. The learning objective of this lab is for students to gain first-hand experiences on the Meltdown attack.
