DDH-based Multisignatures with Public Key Aggregation
Multisignatures Decisional Diffie-Hellman assumption Blockchain
<
2019/7/8
A multisignature scheme allows a group of signers to produce a joint signature on a common message, which is more compact than a collection of distinct signatures from all signers. Given this signatur...
HACKING SPATIAL DATA: AN EXAMPLE OF AGGREGATION PROBLEMS
Spatial aggregation Spatial data science Hacking spatial data Spatial autocorrelation
<
2018/11/8
Many applications using spatially aggregated data tend to treat the spatial units as given. For example, in the United States, analyses using the social and economic data often rely on the existing an...
MapReduce programming paradigm allows to process big data sets in parallel on a large cluster. We focus on a scenario where the data owner outsources her data on an honest-but-curious server. Our aim ...
Aggregate signature allows non-interactively condensing multiple individual signatures into a compact one. Besides the faster verification, it is useful to reduce storage and bandwidth, and is especia...
We focus on a scenario in which a single company wishes to obtain the distribution of aggregate features, while ensuring a high level of privacy for the users. We are interested in the case where user...
Privacy-Preserving Aggregation of Time-Series Data with Public Verifiability from Simple Assumptions
Aggregator Oblivious Encryption Public Verifiability
<
2017/5/31
Aggregator oblivious encryption was proposed by Shi et al. (NDSS 2011), where an aggregator can compute an aggregated sum of data and is unable to learn anything else (aggregator obliviousness). Since...
Practical Secure Aggregation for Privacy Preserving Machine Learning
Privacy Preserving Machine Learning cryptographic protocols
<
2017/3/31
We design a novel, communication-efficient, failure-robust protocol for secure aggregation of high-dimensional data. Our protocol allows a server to compute the sum of large, user-held data vectors fr...
Homomorphic Proxy Re-Authenticators and Applications to Verifiable Multi-User Data Aggregation
data aggregation verifiable computation homomorphic encryption
<
2017/2/20
We introduce the notion of homomorphic proxy re-authenticators, a tool that adds security and verifiability guarantees to multi-user data aggregation scenarios. It allows distinct sources to authentic...

2016/5/31
In axiomatic approaches to expert opinion aggregation, so-called independence conditions have been ubiquitous. Such conditions dictate that the group value assigned to each decision variable should de...
