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. In order to demonstrate feasibility, a proof-of-concept implementation is provided.


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. In the paper ZeroDefectManufacturing.pdf, we first present Product, Process, and Data quality services to drive zero-waste value chain strategies. Following this, we present the Trusted Framework (TF), which is a key enabler for the secure and effective sharing of quality-related information within the supply chain business ecosystem, and thus for quality optimization actions towards zero-defect manufacturing. The TF specification includes the data model and format of the Process/Product/Data (PPD) Quality Hallmark, the OpenAPI exposed to factory system and a comprehensive Identity Management layer, for secure horizontal- and vertical quality data integration. The PPD hallmark and the TF already address some of the industrial needs to have a trusted approach to share quality data between the different stakeholders of the production chain to empower zero-waste value chain strategies.
