D5.1 Security and Trust Models

In this deliverable D5.1 “Security and Trust Models”, we discuss the hardware-supported FE schemes studied in WP5 of FENTEC and describe the security and trust models for the computing platforms executing computations required by the FE schemes. That is, in this deliverable, we solely focus on the implementation layer of the FE schemes and all discussion on efficiency as well as security and trust models are about the implementations rather than the theoretical schemes or algorithms per se. We define a generic computing platform modelling the large variety of computing platforms covered by FENTEC and its use cases. We employ this generic model to define adversarial, security and trust models that cover different types of adversaries as well as layers of security and trust in various possible deployments of FE.
