| * An adversary with access to precise enough information about memory | |
| accesses (typically, an untrusted operating system attacking a secure | |
| enclave) could recover an RSA private key after observing the victim | |
| performing a single private-key operation if the window size used for the | |
| exponentiation was 3 or smaller. Found and reported by Zili KOU, | |
| Wenjian HE, Sharad Sinha, and Wei ZHANG. See "Cache Side-channel Attacks | |
| and Defenses of the Sliding Window Algorithm in TEEs" - Design, Automation | |
| and Test in Europe 2023. | |
