Prover - Toward More Efficient Formal Verification of Masking in Probing Model
Feng Zhou, Hua Chen, Limin Fan
Implementation
In recent years, formal verification has emerged as a crucial method for assessing security against Side-Channel attacks of masked implementations, owing to its remarkable versatility and high degree of automation. However, formal verification still faces technical bottlenecks in balancing accuracy and efficiency, thereby limiting its scalability. Former efficient tools like maskVerif and CocoAlma are often inaccurate when verifying schemes utilizing properties of Boolean functions. Later,...
Formal Definition and Verification for Combined Random Fault and Random Probing Security
Sonia Belaid, Jakob Feldtkeller, Tim Güneysu, Anna Guinet, Jan Richter-Brockmann, Matthieu Rivain, Pascal Sasdrich, Abdul Rahman Taleb
Implementation
In our highly digitalized world, an adversary is not constrained to purely digital attacks but can monitor or influence the physical execution environment of a target computing device. Such side-channel or fault-injection analysis poses a significant threat to otherwise secure cryptographic implementations. Hence, it is important to consider additional adversarial capabilities when analyzing the security of cryptographic implementations besides the default black-box model. For side-channel...
IronMask: Versatile Verification of Masking Security
Sonia Belaïd, Darius Mercadier, Matthieu Rivain, Abdul Rahman Taleb
This paper introduces IronMask, a new versatile verification tool for masking security. IronMask is the first to offer the verification of standard simulation-based security notions in the probing model as well as recent composition and expandability notions in the random probing model. It supports any masking gadgets with linear randomness (e.g. addition, copy and refresh gadgets) as well as quadratic gadgets (e.g. multiplication gadgets) that might include non-linear randomness (e.g. by...
