Research Interests

Coding Schemes for PUFs:

Currently, I am working on different coding schemes in the context of PUFs. This means looking for suitable codes while keeping a trade-off between error correction capability, security and implementation effort in mind.

To find suitable codes, information theory as well as coding theory provide indications of coding schemes which might be useful in a practical sense too.
