A Last-Level Defense for Application Integrity and Confidentiality. (arXiv:2311.06154v1 [cs.CR])

Our objective is to protect the integrity and confidentiality of applications
operating in untrusted environments. Trusted Execution Environments (TEEs) are
not a panacea. Hardware TEEs fail to protect applications against Sybil, Fork
and Rollback Attacks and, consequently, fail to preserve the consistency and
integrity of applications. We introduce a novel system, LLD, that enforces the
integrity and consistency of applications in a transparent and scalable
fashion. Our solution augments TEEs with instantiation control and rollback
protection. Instantiation control, enforced with …
