Testing side-channel security of cryptographic implementations against future microarchitectures
Gilles Barthe, Marcel Böhme, Sunjay Cauligi +7
How will future microarchitectures impact the security of existing cryptographic implementations? As we cannot keep reducing the size of transistors, chip vendors have started deve…
Robust Constant-Time Cryptography
Matthew Kolosick, Basavesh Ammanaghatta Shivakumar, Sunjay Cauligi +4
The constant-time property is considered the security standard for cryptographic code. Code following the constant-time discipline is free from secret-dependent branches and memory…
A Turning Point for Verified Spectre Sandboxing
Sunjay Cauligi, Marco Guarnieri, Daniel Moghimi +2
Spectre attacks enable an attacker to access restricted data in an application's memory. Both the academic community and industry veterans have developed several mitigations to blo…
SoK: Practical Foundations for Software Spectre Defenses
Sunjay Cauligi, Craig Disselkoen, Daniel Moghimi +2
Spectre vulnerabilities violate our fundamental assumptions about architectural abstractions, allowing attackers to steal sensitive data despite previously state-of-the-art counter…
Swivel: Hardening WebAssembly against Spectre
Shravan Narayan, Craig Disselkoen, Daniel Moghimi +8
We describe Swivel, a new compiler framework for hardening WebAssembly (Wasm) against Spectre attacks. Outside the browser, Wasm has become a popular lightweight, in-process sandbo…
Constant-Time Foundations for the New Spectre Era
Sunjay Cauligi, Craig Disselkoen, Klaus v. Gleissenthall +4
The constant-time discipline is a software-based countermeasure used for protecting high assurance cryptographic implementations against timing side-channel attacks. Constant-time…
CT-Wasm: Type-Driven Secure Cryptography for the Web Ecosystem
Conrad Watt, John Renner, Natalie Popescu +2
A significant amount of both client and server-side cryptography is implemented in JavaScript. Despite widespread concerns about its security, no other language has been able to ma…
