Decentralizing Information Technology: The Advent of Resource Based Systems [article]

Aggelos Kiayias
2021 arXiv   pre-print
The growth of the Bitcoin network during the first decade of its operation to a global scale system is a singular event in the deployment of Information Technology systems.  ...  We investigate this question by introducing the concept of resource based systems and their four fundamental characteristics: (i) resource-based operation, (ii) tokenomics, (iii) decentralized service  ...  In Advances in Cryptology - CRYPTO 2017 - 37th Annual International Cryptology Conference, Santa Barbara, CA, USA, August 20-24, 2017, Proceedings, Part I, pages 291–323, 2017.

Accelerating the Search of Differential and Linear Characteristics with the SAT Method

Ling Sun, Wei Wang, Meiqin Wang
2021 IACR Transactions on Symmetric Cryptology  
With the observations and experience in the tests, a strategy on how to create the sets of bounding conditions that probably achieve extraordinary advances is proposed.  ...  Firstly, with the additional encoding variables of the sequential counter circuit for the original objective function in the standard SAT method, we put forward a new encoding method to convert the Matsui's  ...  [ST17b] tology -CRYPTO 2017 -37th Annual International Cryptology Conference, Santa Barbara, CA, USA, August 20-24, 2017, Proceedings, Part III, pages 250-279, 2017.  ...

An Efficient and Robust Committee Structure for Sharding Blockchain [article]

Mengqian Zhang, Jichen Li, Zhaohua Chen, Hongyin Chen, Xiaotie Deng
2021 arXiv   pre-print
In addition, we introduce a referee committee and partial sets in each committee, and design a recovery procedure in case the leader is malicious.  ...  In order to break the performance bottlenecks, we propose a reputation mechanism for selecting leaders. The term of reputation in our design reflects each node's honest computation resources.  ...  Barbara, CA, USA, August 20-24, 2017, Proceed- to process cross-shard transactions.  ...

Scalable and Probabilistic Leaderless BFT Consensus through Metastability [article]

Team Rocket, Maofan Yin, Kevin Sekniqi, Robbert van Renesse, Emin Gün Sirer
2020 arXiv   pre-print
For our implementation and setup, the bottleneck of the system is in transaction verification.  ...  It does not require accurate knowledge of all participants and exposes new possible tradeoffs and improvements in safety and liveness for building consensus protocols.  ...  We quantify the bounds on the discrepancy in Appendix A.7.  ...

Rounded Gaussians [chapter]

Andreas Hülsing, Tanja Lange, Kit Smeets
2018 Lecture Notes in Computer Science  
This paper suggests to use rounded Gaussians in place of discrete Gaussians in rejection-sampling-based lattice signature schemes like BLISS.  ...  We show the effectiveness of the new sampler by applying it to BLISS, prove analogues of the security proofs for BLISS, and present an implementation that runs in constant time.  ...  Advances in Cryptology -CRYPTO 2017 -37th Annual International Cryptology Conference, Santa Barbara, CA, USA, August 20-24, 2017, Proceedings, Part II, volume 10402 of Lecture Notes in Computer Science  ...
