These emergent features are typical of systems at the critical point of continuous phase transitions, and have led to the hypothesis that such systems may self-organize at criticality, i.e. without any fine tuning of parameters. Since the introduction of the Bak-Tang-Wiesenfeld (BTW) model, the paradigm of self-organized criticality (SOC) has been very fruitful for the analysis of emergent collective behaviors in a number of systems, including the brain. Although considerable effort has been devoted in identifying and modeling scaling features of burst and avalanche statistics, dynamical aspects related to the temporal organization of bursts remain often poorly understood or controversial. Of crucial importance to understand the mechanisms responsible for emergent behaviors is the relationship between active and quiet periods, and the nature of the correlations. Here we investigate the dynamics of active (θ-bursts) and quiet states (δ-bursts) in brain activity during the sleep-wake cycle. We show the duality of power-law (θ, active phase) and exponential-like (δ, quiescent phase) duration distributions, typical of SOC, jointly emerge with power-law temporal correlations and anti-correlated coupling between active and quiet states. Importantly, we demonstrate that such temporal organization shares important similarities with earthquake dynamics, and propose that specific power-law correlations and coupling between active and quiet states are distinctive characteristics of a class of systems with self-organization at criticality.","lang":"eng"}],"type":"journal_article","file":[{"file_name":"2020_EPJWebConf_Lombardi.pdf","access_level":"open_access","creator":"dernst","file_size":2197543,"content_type":"application/pdf","file_id":"8144","relation":"main_file","date_created":"2020-07-22T06:17:11Z","date_updated":"2020-07-22T06:17:11Z","success":1}],"oa_version":"Published Version","intvolume":" 230","status":"public","title":"Power-law correlations and coupling of active and quiet states underlie a class of complex systems with self-organization at criticality","ddc":["530"],"_id":"8105","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"file_date_updated":"2020-10-08T08:56:14Z","ec_funded":1,"date_updated":"2021-01-12T08:17:06Z","date_created":"2020-07-19T22:00:59Z","volume":15,"author":[{"last_name":"Edelsbrunner","first_name":"Herbert","orcid":"0000-0002-9823-6833","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","full_name":"Edelsbrunner, Herbert"},{"id":"3E4FF1BA-F248-11E8-B48F-1D18A9856A87","first_name":"Anton","last_name":"Nikitenko","full_name":"Nikitenko, Anton"},{"first_name":"Katharina","last_name":"Ölsböck","id":"4D4AA390-F248-11E8-B48F-1D18A9856A87","full_name":"Ölsböck, Katharina"},{"full_name":"Synak, Peter","id":"331776E2-F248-11E8-B48F-1D18A9856A87","first_name":"Peter","last_name":"Synak"}],"publication_status":"published","publisher":"Springer Nature","department":[{"_id":"HeEd"}],"year":"2020","acknowledgement":"This project has received funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (grant agreements No 78818 Alpha and No 638176).

In a nutshell: a reverse firewall is placed outside of a device and its goal is to “sanitize” the messages sent by it, in such a way that a malicious device cannot leak its secrets to the outside world. It is typically assumed that the cryptographic devices are attacked in a “functionality-preserving way” (i.e. informally speaking, the functionality of the protocol remains unchanged under this attacks). In their paper, Mironov and Stephens-Davidowitz construct a protocol for passively-secure two-party computations with firewalls, leaving extension of this result to stronger models as an open question.\r\nIn this paper, we address this problem by constructing a protocol for secure computation with firewalls that has two main advantages over the original protocol from Eurocrypt 2015. Firstly, it is a multiparty computation protocol (i.e. it works for an arbitrary number n of the parties, and not just for 2). Secondly, it is secure in much stronger corruption settings, namely in the active corruption model. More precisely: we consider an adversary that can fully corrupt up to 𝑛−1 parties, while the remaining parties are corrupt in a functionality-preserving way.\r\nOur core techniques are: malleable commitments and malleable non-interactive zero-knowledge, which in particular allow us to create a novel protocol for multiparty augmented coin-tossing into the well with reverse firewalls (that is based on a protocol of Lindell from Crypto 2001).","lang":"eng"}],"alternative_title":["LNCS"],"type":"conference","language":[{"iso":"eng"}],"conference":{"end_date":"2020-08-21","start_date":"2020-08-17","location":"Santa Barbara, CA, United States","name":"CRYPTO: Annual International Cryptology Conference"},"doi":"10.1007/978-3-030-56880-1_26","quality_controlled":"1","project":[{"name":"Teaching Old Crypto New Tricks","call_identifier":"H2020","_id":"258AA5B2-B435-11E9-9278-68D0E5697425","grant_number":"682815"}],"main_file_link":[{"url":"https://eprint.iacr.org/2019/1317","open_access":"1"}],"oa":1,"month":"08","publication_identifier":{"issn":["03029743"],"eissn":["16113349"],"isbn":["9783030568795"]},"date_created":"2020-08-30T22:01:12Z","date_updated":"2021-01-12T08:18:08Z","volume":12171,"author":[{"id":"B9CD0494-D033-11E9-B219-A439E6697425","first_name":"Suvradip","last_name":"Chakraborty","full_name":"Chakraborty, Suvradip"},{"full_name":"Dziembowski, Stefan","first_name":"Stefan","last_name":"Dziembowski"},{"full_name":"Nielsen, Jesper Buus","first_name":"Jesper Buus","last_name":"Nielsen"}],"publication_status":"published","department":[{"_id":"KrPi"}],"publisher":"Springer Nature","year":"2020","acknowledgement":"We would like to thank the anonymous reviewers for their helpful comments and suggestions.

The literature contains a wealth of useful theorems about the behavior of discrete Gaussians under convolutions and related operations. Yet despite their structural similarities, most of these theorems are formally incomparable, and their proofs tend to be monolithic and written nearly “from scratch,” making them unnecessarily hard to verify, understand, and extend.\r\nIn this work we present a modular framework for analyzing linear operations on discrete Gaussian distributions. The framework abstracts away the particulars of Gaussians, and usually reduces proofs to the choice of appropriate linear transformations and elementary linear algebra. To showcase the approach, we establish several general properties of discrete Gaussians, and show how to obtain all prior convolution theorems (along with some new ones) as straightforward corollaries. As another application, we describe a self-reduction for Learning With Errors (LWE) that uses a fixed number of samples to generate an unlimited number of additional ones (having somewhat larger error). The distinguishing features of our reduction are its simple analysis in our framework, and its exclusive use of discrete Gaussians without any loss in parameters relative to a prior mixed discrete-and-continuous approach.\r\nAs a contribution of independent interest, for subgaussian random matrices we prove a singular value concentration bound with explicitly stated constants, and we give tighter heuristics for specific distributions that are commonly used for generating lattice trapdoors. These bounds yield improvements in the concrete bit-security estimates for trapdoor lattice cryptosystems.","lang":"eng"}],"page":"623-651","citation":{"ama":"Genise N, Micciancio D, Peikert C, Walter M.
