Maintaining security is a constantly shifting task, and we need to respond with continuous learning and research. The portfolio of SAP Security Research contains those topics that we believe are most important for SAP’s security future.

SAP’s vision to secure business is built on 3 ideals: Zero-Vulnerability, to harden the software by eliminating vulnerabilities, Defensible Application, to enable the software to identify and prevent attacks, and Zero-Knowledge, to make any theft of data useless through encryption.

Considering these aspects, SAP Security Research covers the following focal areas: Anonymization for Big Data, Secure Internet of Things, Software security analysis, Open-source analysis, Deceptive application, Applied cryptography, Quantum technology, and Machine Learning as enabler for the next generation of security.




This internship is based in the SAP Labs France Research Lab, in Sophia-Antipolis. The work will be performed in the context of the Research Program “SAP Security Research”, under the “Open-Source Security Analysis” topic. Nowadays software applications include more and more open-source (OSS) libraries. Automated package management tools allow developers to find and integrate libraries in their projects with minimal effort. While automated dependency management simplifies software reuse, there is no guarantee that the software package automatically downloaded from the package repository (e.g., Maven Central)  originates from the build of the library source-code available ,e.g., at

The goal of the internship is to establish whether all the bytecode in the software package originates from the source code of the library repository (thereby establishing its integrity) or whether it also includes bytecode whose origin cannot be established and may be potentially malicious.




The expected work is to investigate techniques to compare source-code and bytecode to develop an approach and tooling to compare Java source code with Java bytecode. In particular the approach must be able to establish a distance measure in case there is no exact match.

Some of the tasks to be addressed shall include:

  • Explore state of the art on code comparison/code cloning
  • Explore alternative intermediate representations for Java code
  • Develop proof of concept for Java source-code/bytecode comparison
  • Experiment the proposed solution on libraries hosted in Maven Central

We expect that 60% of time will be dedicated to development and 40% to research activities.




  • University Level: Last year of MSc in Computer Science or beyond
  • Good knowledge of the Java programming language, Maven 
  • Good knowledge of software intermediate representations (optional)
  • Good knowledge of versioning control systems like Git 
  • Good skills in modelling, analysis and programming (Java, Python)
  • Fluency in English (working language)
  • Abilities in organizing meeting and contacting people
  • Good oral and written communication skills
  • Capacity to write documents in English, ability to synthesize




  • None required
