Formal Methods for Modelling and Analysis of Single-Event Upsets
2015
2015 IEEE International Conference on Information Reuse and Integration
Preserved Fulltext
In this paper we develop a formal semantic framework for easy formal modelling of a large variety of SEUs in a core assembly language capturing the essential features of the ARM assembly language. ...
We use this framework to formally prove the soundness of a static analysis enforcing so-called blue/green separation in a given program. ...
CONCLUSION We have formalised TinyARM, an assembly language close to the ARM language, and several fault models based on bitflips of varying degree of potency: data, flags, control registers or instruction ...

We propose a method that can verify both absence of runtime errors (i.e. crashes) and absence of privilege escalation (i.e. exploits) in embedded kernels from their binary executables. ...
It is thus desirable to guarantee that a kernel is free from these bugs using formal methods, but the high cost and expertise required to do so are deterrent to wide applicability. ...

Fault-injection attacks have been proven in the past to be a reliable way of bypassing hardware-based security measures, such as cryptographic hashes, privilege and access permission enforcement, and trusted ...
However, traditional fault-injection attacks require physical presence, and hence, were often considered out of scope in many real-world adversary settings. ...
We provide a stripped down version of the relevant parts of the code in Listing 4, highlighting the most important parts in the form of inline assembly for clarity. ...
