Deliverable 5.7 Security software modules: Iteration 1

This document introduces the software security models that will be implemented in order to protect the neuromorphic accelerator of the NEUROPULS Horizon Europe project (Grant Agreement n° 101070238) from malicious agents. The two main protocols discussed are authentication and static remote software attestation, both of which are described in detail with a particular focus on the most recent advancements found inthe literature. The remote attestation literature review specifically presents papers that have been published in sufficiently reputable venues in the past 5 years, with particular attention given to protocols that are deployed on IoT systems while leveraging physically unclonable functions (PUFs). The authentication part also focuses on protocols that are based on PUFs and provide enough security while keeping the power requirements low, which is a key aspect of the deployment on IoT devices. An authentication protocol is proposed after careful consideration, while more advanced protocols for both authentication and remote software attestation will be presented in the second iteration of this deliverable.
