We are seeking a highly motivated Master’s Thesis Student (M/F/D) to join our R&D team in Munich to work at the frontier of computer science and cyber security.
Objective: harness Artificial Intelligence (AI) to detect and prevent real-world cryptographic vulnerabilities.
Cryptography may be secure in theory, but in practice even a single subtle coding error can undermine security of an entire system. With the rise of advanced AI systems, especially Large Language Models (LLMs), we now have unprecedented tools to analyse source code, detect cryptographic weaknesses, and even propose hardened improvements.
Your thesis will directly contribute to this emerging research field and address such questions as:
Can AI consistently recognize subtle weaknesses in cryptographic implementations?
Can AI lead developers toward secure, high-assurance cryptographic code?
Key Objectives
Design and implement a tool chain that evaluates and validates AI-assisted cryptographic coding
Define test scenarios, use cases, and representative code bases for assessing multiple AI systems
Experiment, benchmark, and optimize AI-driven analysis and code improvement workflows
Generate publishable research insights and contribute to an ongoing R&D project
Knowledge, skills and experience required
Bachelor’s degree in Computer Science or related field
Foundational knowledge in Machine Learning, AI, LLMs
Strong programming skills in C/C++ and Python
Understanding of secure-coding principles
Knowledge of cryptographic algorithms and protocols (strong plus)
Proficient in written and spoken English.
Benefits
Possibility to work in an international, multicultural environment.
Strong team-oriented and friendly work culture.
Flexible working hours model and the possibility of remote work.
Fitness-, travel cost- and kindergarten allowance as well as drinks and fruits for free.
