Artifacts:

Advanced Low Power Security
ALPS proposes a solution for a sustainable secure communication for LPWAN-devices summarized- and mentioned in this document as ALPS for Advanced Low Power Security. ALPS uses established cryptographic primitives and combines them according to a framework in order to help solution-architects and other decision-makers, which are facing the mentioned restrictions, requirements and associated challenges.

OraclesLink: An architecture for secure oracle usage
Smart contracts encode critical application logic for realizing digital agreements in a tamper-proof form. Blockchains guarantee that smart contracts cannot be altered after the first deployment and that the execution is strictly followed. Smart contracts can only operate on data available on-chain. Oracles are bridging the gap between on-chain and off-chain data. Oracles introduce a wide range of security risks, which were already exploited in publicly known hacks. In this paper OraclesLink is proposed, which is a secure and developer-friendly architecture for using oracles within smart contracts. The goal of the architecture is to eliminate single points of failure and single sources of truth through distribution.

A blockchain-based framework for trusted quality data sharing towards zero-defect manufacturing
There is a current wave of a new generation of digital solutions based on intelligent systems, hybrid digital twins and AI-driven optimization tools to assure quality in smart factories. Such digital solutions heavily depend on quality-related information within the supply chain business ecosystem to drive zero-waste value chains. To empower zero-waste value chain strategies with meaningful, reliable, and trustful data, there must be a solution for end-to-end industrial data traceability, trust, and security across multiple process chains or even inter-organizational supply chains.
