The talk "Scheduled Disclosure: Turning Power Into Timing Without Frequency Scaling" introduces a groundbreaking new class of side-channel attacks that redefines the landscape of remote timing vulnerabilities on modern processors. Presented by Inwhan Chun, Isabella Siu, and Riccardo Paccagnella at IEEE S&P, this research demonstrates that power side-channel information can be converted into observable timing differences, even in the complete absence of traditional frequency scaling mechanisms. This discovery is particularly significant because it bypasses long-standing assumptions about processor power management and challenges the effectiveness of widely adopted security countermeasures, such as constant-time code.
