Selected R&D Projects

PRIViLEDGE

Project homepage
Twitter
PRIViLEDGE realises cryptographic protocols supporting privacy, anonymity, and efficient decentralised consensus for DLTs. In PRIViLEDGE, several European key players in cryptographic research and from the fintech and blockchain domains unite to push the limits of cryptographic protocols for privacy and security. Results from PRIViLEDGE are demonstrated through four ledger-based solutions: verifiable online voting, contract validation and execution for insurance, university diploma record ledger, and update mechanism for stake-based ledgers. Guardtime is the coordinator of the project.

SOFIE

Twitter
The SOFIE project aims to develop a blockchain driven federated platform for enabling information exchange of different IoTs and data silos. Secure open federation is the key concept of the SOFIE approach. The aim is to enable creation of business platforms, based on existing IoT platforms and distributed ledgers, without needing to negotiate with any gatekeepers. The wide applicability of the approach is tested through four pilots.

RESISTO

Project homepage
Twitter
RESISTO is an innovative solution for Communication Infrastructure providing holistic (cyber/physical) situation awareness and enhanced resilience. RESISTO will help Communications Infrastructures Operators to take the best countermeasures and reactive actions exploiting the combined use of risk and resilience preparatory analyses, detection and reaction technologies, applications and processes in the physical and cyber domains.

SYSFLEX

Project homepage
Twitter
EU-SysFlex stands for “Pan-European system with an efficient coordinated use of flexibilities for the integration of a large share of RES “. EU-SysFlex will come up with new types of services that will meet the needs of the system with more than 50% of renewable energy sources. It will find the right blend of flexibility and system services to support secure and resilient transmission system operation.

BLT

Read the news
KSI blockchain technology employs one-way hash functions to generate digital signatures that can prove the time, integrity and attribution of origin for electronic data. BLT extends this approach to provide human and machine identity management, with a level of non-repudiation consistent with existing digital signature schemes. Through this methodology, BLT benefits include simplified revocation management, long-term validity, limited liability, quantum immunity.

Blocklab: Energy Grid

Read the news
The Blocklab project focuses on how smart meters can securely and privately store data in a blockchain. The storage element is an important pillar for the blockchain based energy market since all partners have access to all data. The project asks how to ensure the authenticity of the sender (the smart meter) and its data. Blocklab is funded under a contract awarded by the Dutch government and the city of Rotterdam, and managed by BlockLab, a subsidiary of the Port of Rotterdam. BlockLab develops use cases with alliances including engineers, developers and end users, with a focus on energy and logistics.

ECHO

PROJECT HOMEPAGE
Twitter
ECHO delivers an organized and coordinated approach to improve proactive cyber defence of the European Union, through effective and efficient multi-sector collaboration. The Partners will execute on a 48-month work plan to develop, model and demonstrate a network of cyber research and competence centres, with a central competence at the hub. The Central Competence Hub serves as the focal point for the ECHO Multi-sector Assessment Framework enabling multi-sector dependencies management, provision of an ECHO Early Warning System, an ECHO Federation of Cyber Ranges and management of an expanding collection of Partner Engagements.

BC4Space

Read the news
BC4Space, carried out under the European Space Agency, validates how KSI blockchain technology can be used to verify the integrity and provenance of Earth Observation data sets and support end-user adoption. Blockchain technology enables the full end-to-end chain of custody for data through its lifecycle and guarantees the integrity of process for applications that collect and make decisions based on actionable reports.

KISS

Read the news
Funded by the U.S. Department of Energy, the Keyless Infrastructure Security System (KISS) project pilots two use cases to test and demonstrate blockchain’s ability to increase the cybersecurity resilience of electricity infrastructure. The first use case focused on securing critical data stored and exchanged between the energy management system or distribution management system and energy delivery systems. The second use case demonstrated how blockchain can help improve asset management and supply chain security for critical energy delivery systems.

Participation in International Forums

Our active participation in various international organizations supports Guardtime’s strong position in the European Union policy-making processes. We see that collaboration between industry, research organisations and policymakers is necessary to define and engage in R&D efforts that meet market needs.

We have initiated different formats for and remain committed to the EU, regional and domestic cooperation between public, private and academic counterparts.

For example, Guardtime is the founding member and an active participant at the European Cyber Security Organization (ECSO), International Association for Trusted Blockchain Applications (INATBA), European Organization for Security (EOS), North European Cybersecurity Cluster (NECC) and the Estonian Information Security Association (EISA). We contribute to the work of European Blockchain Partnership, EU Blockchain Observatory and Forum, Cybersecurity Tech Accord as well as the CEN/CLC Blockchain Focus Group.
