HoTSoS identifies itself as “research event centered on the Science of Security, which aims to address the fundamental problems of security in a principled manner.” Because the seminal Spectre paper won NSA’s Best Scientific Cybersecurity Paper Competition last year, its authors were invited to give a keynote speech at the symposium. Given that the corresponding vulnerabilities were disclosed to Intel almost 4 years ago, we (the authors) decided to take a step back and to look, in HotSoS’ spirit, at the fundamental problems. We (Cyberus Technology) feel deeply honoured that we were entrusted with delivering the talk and want to give you a sneak preview of what to expect.
- Iron Law of processor performance
- Memory latency, caching, and side-channels
- Turing machine and performance increase through parallelism
- Control flow discontinuities: branch history (BHT) and branch targets (BTB)
- Spectre v1 (BHT) and v2 (BTB)
By the way, the conference is fully virtual this year and registration is open to everybody for free. The keynote is scheduled for April 14th, 15:35 CEST (9:35am EDT).read more
