Cryptography-based security solutions heavily rely on cryptographic primitives such as encryption and signature schemes. However, existing primitives are threatened by attacks which are made possible by new computing architectures and algorithms. Also, new cryptographic solutions require efficient primitives with new functionalities such as fully homomorphic encryption. Thus, the goal of this project area is the development of the required cryptographic primitives. They must be efficient in present and future computing environments, and must resist novel attacks due to new hardware platforms and algorithmic advances.

P3 – Hardware-Entangled Cryptography

Physically Unclonable Functions (PUFs) are a promising approach to realize minimal trust anchors for embedded devices. This project will design novel PUF-based security primitives. On top of this, it will build efficient and scalable PUF-based device identification and authentication schemes providing intrinsic protection against basic hardware attacks. The project will develop a formal security framework to analyze the security of the developed solutions according to modern cryptographic standards.

S2 -Attestation Protocols

The goal of this project area is to provide cryptography-based security solutions that match all the necessary functional requirements to establish trust in new and next generation computing environments. Such solutions have been and will be indispensable to establish trust in the identities and properties of actors, in the soundness of their devices, and in the proper functioning and privacy-friendliness of services.

Embedded and mobile systems are more and more used in security- and safety-critical applications. This generates an increasing need for enabling technologies to validate and verify the integrity of a system's software state against malicious code. This project will design and develop novel attestation schemes that allow to validate and verify the software integrity and trustworthiness of remote devices, cover runtime attacks, do not require complex and/or costly security hardware, are secure in stronger adversary models than existing approaches, and that do not solely rely on standard cryptographic techniques.
