On the Challenges of Detecting Side-Channel Attacks in SGX. (arXiv:2011.14599v2 [cs.CR] UPDATED)

Existing tools to detect side-channel attacks on Intel SGX are grounded on
the observation that attacks affect the performance of the victim application.
As such, all detection tools monitor the potential victim and raise an alarm if
the witnessed performance (in terms of runtime, enclave interruptions, cache
misses, etc.) is out of the ordinary.

In this paper, we show that monitoring the performance of enclaves to detect
side-channel attacks may not be effective. Our core intuition is that all
monitoring …
