"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."
