human: Given a node-centered hypergraph: <hypergraph>, where nodes represent papers and hyperedges represent sets of papers co-cited by a source paper.

Details of the hypergraph:
Center node: "formally secure compilation of unsafe low level components extended abstract"
  Abstract: We propose a new formal criterion for secure compilation, providing strong security guarantees for components written in unsafe, low-level languages with C-style undefined behavior. Our criterion goes beyond recent proposals, which protect the trace properties of a single component against an adversarial context, to model dynamic compromise in a system of mutually distrustful components. Each component is protected from all the others until it receives an input that triggers an undefined behavior, causing it to become compromised and attack the remaining uncompromised components. To illustrate this model, we demonstrate a secure compilation chain for an unsafe language with buffers, procedures, and components, compiled to a simple RISC abstract machine with built-in compartmentalization. The protection guarantees offered by this abstract machine can be achieved at the machine-code level using either software fault isolation or tag-based reference monitoring. We are working on machine-checked proofs showing that this compiler satisfies our secure compilation criterion.
