    Research output: Chapter in Book/Report/Conference proceedingChapterAcademic


    In this chapter we explain why security is important in an ambient intelligent (AmI) environment. In order to achieve trust and security in this environment not only cryptographic algorithms are needed, but also secure methods for generation and storage of secret keys. Physical uncloneable functions (PUFs) can be used to this end, because they have built in security properties, such as uncloneability and tamper evidence. We show that cryptographic keys can be extracted securely from PUFs. This enables one to go beyond simple identification applications. In particular, more advanced protocols, such as authentication, key exchange, certified execution, and proofs of execution, can be based on PUFs.
