RRTxFM: Probabilistic Counting for Differentially Private Statistics
Probabilistic Counting Differential Privacy Randomized Response
2019/7/15
Data minimization has become a paradigm to address privacy concerns when collecting and storing personal data. In this paper we present two new approaches, RSTxFM and RRTxFM, to estimate the cardinali...
Separable Statistics and Multidimensional Linear Cryptanalysis
block ciphers multidimensional linear cryptanalysis separable statistics
2017/10/12
Multidimensional linear cryptanalysis of block ciphers is improved in this work by introducing a number of new ideas. Firstly, formulae is given to compute approximate multidimensional distributions o...
A Statistics-based Fundamental Model for Side-channel Attack Analysis
Side-channel attack maximum likelihood estimation success rate
2016/1/25
Side-channel attacks (SCAs) exploit leakage from the physical
implementation of cryptographic algorithms to recover the otherwise
secret information. In the last decade, popular SCAs like differenti...
Verifiable Order Queries and Order Statistics on a List in Zero-Knowledge
order queries order statistics zero-knowledge
2016/1/7
Given a list L with n elements, an order query on L asks whether a given element x ∈ L precedes or
follows another element y ∈ L. More generally, given a set of m elements from L, an order query asks...
Method to secure data in the cloud while preserving summary statistics
Paillier encryption Sum- mary statistics
2014/3/6
In this paper we propose a method which will preserve sum- mary statistics of data organized in a two way table. We have shown that fully homomorphic encryption is a powerful solution. However it has ...
We ask the question – how can websites and data aggregators continually release updated statistics, and meanwhile preserve each individual user’s privacy? We propose a differentially private continual...
Current work in RFID security focuses mainly on authentication
and privacy preserving identification. In this paper,
we discuss the possibility of widening the scope of RFID
security by introducing...
Statistics of Random Permutations and the Cryptanalysis Of Periodic Block Ciphers
Generating Functions EGF OGF Random Permutations
2009/6/12
A block cipher is intended to be computationally indistinguishable from a random permutation
of appropriate domain and range. But what are the properties of a random permutation? By
the aid of expon...
In recent years there has been massive progress in the development of technologies for storing
and processing of data. If statistical analysis could be applied to such data when it is distributed bet...
GNFS (general number field sieve) algorithm is currently the fastest known
algorithm for factoring large integers. Up to the present, several running time
estimates for GNFS are announced (ex. [LV00...
