ACM CCS
Successful submissions of CRISP-Researchers
The ACM Conference on Computer and Communications Security (ACM CCS) is the world's largest academic conference on communications security and cybersecurity (CCS). Also this year numerous submissions of the Darmstadt cybersecurity experts were accepted.
The papers accepted at the main conference were written by scientists from the TU Darmstadt and the Fraunhofer SIT:
Generalized State Channel Networks
Authors: Stefan Dziembowski, Sebastian Faust, Kristina Hostakova
Abstract
An extension of virtual payment networks to cryptocurrencies are so-called state-channel networks. In addition to simple virtual off-chain payments, these enable the execution of any complex smart contract in channel networks. In this work, generic state channels are introduced, formally specified and examined for their safety.
FairSwap: How to fairly exchange digital goods
Authors: Stefan Dziembowski, Lisa Eckey, Sebastian Faust
Abstract
With FairSwap, the scientists present a new protocol for the fair exchange of digital goods with the help of Smart Contracts. The solution has two peculiarities that make it particularly interesting for large files: the cost of running the smart contract on the blockchain is minimal, and instead of expensive cryptographic tools such as zero-knowledge evidence, simple hashing techniques are used.
HyCC: Compilation of Hybrid Protocols for Practical Secure Computation
Authors: Niklas Büscher, Daniel Demmler, Stefan Katzenbeisser, David Kretzmer, Thomas Schneider
Abstract
HyCC is a compiler that automatically generates privacy-preserving multi-party computations from a high-level programming language (a subset of ANSI C). HyCC is the first compiler that combines multiple cryptographic protocols. This allows developers without knowledge in cryptography to develop secure and efficient software.
Domain Validation ++ for MitM-Resilient PKI
Authors: Markus Brand, Tianxiang Dai, Amit Klein, Haya Shulman, Michael Waidner
Abstract
The security of Internet-based applications fundamentally relies on the trustworthiness of Certificate Authorities (CAs). We practically demonstrate for the first time that even a very weak offpath attacker can subvert the trustworthiness of popular commercially used CAs. We propose countermeasures to mitigate our attacks.
The following papers were also accepted for the Pre-Conference Workshops on the eve of the main conference:
2nd International Workshop on Multimedia Privacy and Security (MPS 2018)
Double Embedding Steganalysis
Authors: Martin Steinebach, André Ester, Sascha Zmudzinski
17. Workshop on Privacy in the Electronic Society (WPES’18)
Examining Leakage of Access Counts in ORAM Constructions
Authors: Nikolaos P. Karvelas, Amos Treiber, Stefan Katzenbeisser
Towards Efficient Privacy-Preserving Similar Sequence Queries on Outsourced Genomic Databases
Authors: Oleksandr Tkachenko, Thomas Schneider
ACM CCS 2018 will be held October 15-19, 2018 in Toronto, Canada.
