Cerberus: A Formal Approach to Secure and Efficient Enclave Memory Sharing. (arXiv:2209.15253v2 [cs.CR] UPDATED)

Hardware enclaves rely on a disjoint memory model, which maps each physical
address to an enclave to achieve strong memory isolation. However, this
severely limits the performance and programmability of enclave programs. While
some prior work proposes enclave memory sharing, it does not provide a formal
model or verification of their designs. This paper presents Cerberus, a formal
approach to secure and efficient enclave memory sharing. To reduce the burden
of formal verification, we compare different sharing models and choose …
