Internship Proposal: Analysis and Mitigation of Compiler-Induced Security Weaknesses in Secure C Code Context
When developing secure software in C, especially for cryptographic and embedded systems, the freedom compilers have to reorder or optimize code can unintentionally weaken security countermeasures. Unlike assembly, where the developer has full control over instruction ordering, C compilers apply optimizations that may alter the intended security properties of the code. This behavior depends on the compiler type and the compilation options used
Internship Objectives
The key objectives include:
* Identification of Compiler-Induced Security Weaknesses
Analyze existing public masked cryptographic implementations to discover other instances where compiler optimizations weaken security countermeasures.
* Comparative Study of Compiler Behaviors
Investigate how different compilers and their compilation options affect the security properties of these implementations.
* Establishment of Security-Preserving Compilation Conditions
Formulate conditions or guidelines under which compiler-generated code maintains critical security properties.
YOUR SKILLS & EXPERIENCES
* Computer science / engineering student in a Belgian high-school / university
* Knowledge of C language
* Interest in security
* Interest in low-level code and ARM assembly
Please note: This is an unpaid internship.
