Robot Table Cleaning Toy Example15.12.2023: „How to Raise a Robot” - Extended Version on arXiv

For our SACMAT poster, there is now a follow-up extended version on arXiv under the subtitle “A Case for Neuro-Symbolic AI in Constrained Task Planning for Humanoid Assistive Robots”. We report on new experiments with the unification of robot task planning and access control via Large Language Models, and show how different levels of neuro-symbolic integration can further strengthen this unification.

Ausschnitt aus dem von Let It TEE erzeugten Graphen.10/10/2023: "Let It TEE" - Publication at DISC'23

At the 37th International Symposium on Distributed Computing (DISC'23), October 9-13, 2023, in L'Aquila, Italy, we presented our work Let It TEE. We showed that the consensus algorithm DAG-Rider can be transformed using Trusted Execution Environments, such as Intel SGX, such that up to 49% of protocol participants can be malicious while progress can still be made.

SACMAT Poster Thumbnail08/06/2023: „How to Raise a Robot“ – Poster at SACMAT'23

During the 28th ACM Symposium on Access Control Models and Technologies at the Fondazione Bruno Kessler in Trento, Italy, we have presented our poster „How to Raise a Robot - Beyond Access Control Constraints in Assistive Humanoid Robots”. In the poster, we discuss how humanoid assistive robots can be granted both the necessary level of autonomy for their versatile learning and action capabilities, and how the robots can still learn to respect various constraints such as access control and beyond. In addition to the poster and poster abstract, the publication also includes the presentation video.

Verteidigung Oliver05/22/2023: Successful PhD Graduation - Oliver Stengele

Today, our staff member Oliver Stengele successfully defended his dissertation. For his work titled "Decentralizing Software Identity Management", Oliver researched approaches that enable developers to sovereignly establish and manage unique identities for software. Additionally, he implemented a digital time capsule on the Ethereum blockchain and employed it as part of an independent review process. We congratulate our colleague!

An Extend-only Directed Poset under Modification04/05/2023: Publication “On Extend-Only Directed Posets and Derived Byzantine-Tolerant Replicated Data Types”

We present our new publication “On Extend-Only Directed Posets and Derived Byzantine-Tolerant Replicated Data Types” at this year's Workshop on Principles and Practice of Consistency for Distributed Data. In the paper, we show a new formalization of the decentralized Matrix system using directed partially-ordered sets, which allow a more extensive model than previous approaches based on directed acyclic graphs. The Extended Version on Arxiv is freely available already.

Dave: "Can you bring me the medicine?" Robot: "I am sorry. I am unable to do that."2022-07-28: Blue Sky Paper on the Combination of Access Control and Assistive Humanoid Robotics

In the not too distant future, assistive humanoid robots will provide versatile assistance for coping with everyday life. In their interactions with humans, not only safety, but also security and privacy issues need to be considered. We therefore argue that it is time to bring task planning and execution as a well-established field of robotics with access and usage control in the field of security and privacy closer together. As part of the JuBot Project, we do research on those issues together with the H2T research group. Our first paper with the title BlueSky: Combining Task Planning and Activity-Centric Access Control for Assistive Humanoid Robots published on SACMAT'22 is now freely available as Open Acces.

Decentralizing Watchtowers for Payment Channels Using IPFS2022/07/11: Paper on Decentralization of Watchtowers at DINPS'22 Workshop

Payment Channels enable scalable payments on blockchains but require that users are regularly online to defend their channels against fraud. This task can be outsourced to third parties, so called watchtowers. At the DINPS'22 workshop, we presented an idea to decentralize watchtowers so that users do not need to trust specific employed watchtowers but a user can be defended by any watchtower.

Marc Leinweber hält einen Vortrag2022/06/23: Talk and Paper on Decentralized ticket systems for Mobility-as-a-Service

Mobility-as-a-Service is in the focus of public and private actors as a development step of public transport. We have investigated which disadvantages arise in such a system due to central providers and how these disadvantages can be compensated by decentralization. We presented our current findings as well as open issues for ongoing and future research at the "14. Wissenschaftsforum Mobilität" in Duisburg in June 2022.

Vortrag von Matthias Grundmann auf FC'222022/05/11: Paper on P2P network of Bitcoin at Financial Cryptography and Data Security 2022

The number of peers in the P2P network of Bitcoin is difficult to measure. Together with two students we developed a method to estimate the number of active peers in the network - including reachable and unreachable peers. At the Financial Cryptography and Data Security 2022 we published results of applying this method to data collected through our Bitcoin Monitoring.

Logo IEEE ICBC2022/05/04: Paper and Poster at IEEE ICBC 2022

We presented a short paper about insights into the Bitcoin P2P network at the IEEE International Conference on Blockchain and Cryptocurrency in May 2022. We show for example that the current connection capacity of a majority of the peers is fully used. Matthias Grundmann also presented a poster in which we show how security properties of payment channel protocols can be verified.

The concept of our course is inspired by the same-titled series of COMSYS at the RWTH Aachen.

The Matrix Event Graph is the backbone of a topic-based publish-subscribe system and presents a replicated data type for append-only causal histories of events.2021-02-22: Publication of the “Analysis of the Matrix Event Graph Replicated Data Type”

In the Open Access journal IEEE Access, our article Analysis of the Matrix Event Graph Replicated Data Type was published. With the aim of application in decentralized publish-subscribe systems, in the paper, we extract and analyze the Matrix Event Graph(MEG) from the Matrix middleware, which is primarily used there to depict the causal history of chat messages. We show that the MEG is a so-called Conflict-Free Replicated Data Type, and thereby provides Strong Eventual Consistency. In addition, we show that the MEG, via its reduced notion of consistency when compared to traditional Distributed Ledger Technologies, can cope with environments where the majority of the participants exhibit byzantine faults. We close the article with an analysis of the scalability in form of the number of parallel causal chains in the MEG, for which we can expect an almost optimal evolution according to our results.

We also briefly touch on trade-offs that arise in a practical deployment.

2020/06/11: Matrix Decomposition: Analysis of an Access Control Approach on Transaction-based DAGs without Finality vorgestellt auf der SACMAT 2020

At the 25th ACM Symposium on Access Control Models and Technologies, we presented our paper Matrix Decomposition: Analysis of an Access Control Approach on Transaction-based DAGs without Finality. In this paper, we decompose, abstract and analyze the access control approach of the Matrix middleware for decentralized applications, and show that Matrix can be seen as a Distributed Ledger Technology without strict Consensus. This has interesting consequences when compared to traditional access control approaches, which we discuss as well.

The talk was recorded, and will be publishde by SACMAT at a later date. The publication was also the topic of this blog post on Matrix.org, which covers the Matrix.org view on our findings.
