Designing Reliable Permission Models with Lean 4
The article discusses the development of reliable permission models using Lean 4, a programming language that also serves as a theorem prover. It emphasizes the importance of mathematically enforcing security invariants in complex authorization systems. The tutorial guides users through the installation of Lean 4 and the creation of a project that combines executable programs with mathematical proofs.
- ▪Lean 4 is a programming language, compiler, and theorem prover that helps in designing secure permission models.
- ▪The tutorial covers installing Lean 4, creating a project, and writing executable programs with mathematical proofs.
- ▪The goal is to make important security assumptions difficult to violate through mathematical enforcement.
