Silicon Salon Overview
The Blockchain Commons presentation again led off the day.
Andrew Poelstra Presentation
Anti-Exfil: Preventing Key Exfiltration Through Signature Nonce Data. Secure nonce generation is critical to EC signature generation. If a hardware wallet fails to generate these nonces uniformly at random, then key leakage will occur. This talk introduces “anti-exfil”, a two-round interactive protocol for producing a signature.
Luke Leighton & David Calderwood Presentation
Scalar and Vector Draft Biginteger instructions for the Power ISA. Most RISC ISAs are missing instructions that allow for easy chaining to create Vector results for biginteger operation. This presentation describes the need for 3-in 2-out instructions that greatly simplify biginteger operations as a key strategic requirement for semiconductor design.
Cramium Labs Presentation
Pitfalls and Approaches to Open Source Security Semiconductor. It’s not straightforward to extend the open-source approach to security semiconductors. This talk describes some open-source history, explains Cramium’s approach to navigating these problems, and provides at least some of the benefits of open source in the context of semiconductor design.
