human: Given a hyperedge-centered hypergraph: <hypergraph>, where the center hyperedge is induced by one source paper and its member nodes are the cited papers.

Details of the hypergraph:
Center hyperedge (induced by source paper "camouflage hardware assisted cfi for the arm linux kernel"):
  Abstract: Software control flow integrity (CFI) solutions have been applied to the Linux kernel for memory protection. Due to performance costs, deployed software CFI solutions are coarse grained. In this work, we demonstrate a precise hardware-assisted kernel CFI running on widely-used off-the-shelf processors. Specifically, we use the ARMv8.3 pointer authentication (PAuth) extension and present a design that uses it to achieve strong security guarantees with minimal performance penalties. Furthermore, we show how deployment of such security primitives in the kernel can significantly differ from their user space application.

Includes members:
  Member "protecting the stack with paced canaries":
    also connected through other hyperedges:
      - Hyperedge HE-1 (induced by source paper "arm pointer authentication based forward edge and backward edge control flow integrity for kernels")
  Member "pac it up towards pointer integrity using arm pointer authentication":
    also connected through other hyperedges:
      - Hyperedge HE-2 (induced by source paper "using name confusion to enhance security")
