Synthct: towards portable constant-time code

WebIn this paper, we lay the foundations for constant-time in the presence of speculative and out-of-order execution. We focus on constant-time for two key reasons. First, impact: constant-time pro-gramming is largely used in narrow, high-assurance code—mostly cryptographic implementations—where developers already go to WebConstant-time (CT) programming is a software development methodology where programs are carefully written to avoid these channels. In a nutshell, the idea is to only pass secret …

WebJul 10, 2024 · If constant-time is a non-negotiable goal, one may be forced to use some of the aforementioned tricks to generate branchless code, making the code less clear. Also, performance is often a secondary and quite important goal, so the developer has to hope that the compiler will infer the intended operation behind the branchless code and emit an … WebSep 11, 2024 · SynthCT: Towards Portable Constant-Time Code.
