Finite mixture regression: A sparse variable selection by model selection for clustering [PDF]
, 2014 We consider a finite mixture of Gaussian regression model for high- dimensional data, where the number of covariates may be much larger than the sample size. We propose to estimate the unknown conditional mixture density by a maximum likelihood estimator,

DAGS: Key encapsulation using dyadic GS codes
Journal of Mathematical Cryptology, 2018 Code-based cryptography is one of the main areas of interest for NIST’s Post-Quantum Cryptography Standardization call. In this paper, we introduce DAGS, a Key Encapsulation Mechanism (KEM) based on quasi-dyadic generalized Srivastava codes.

Blockchain Certificateless Encryption Mechanism Based on National Secret Algorithm [PDF]
Jisuanji kexueThe blockchain has attracted widespread attention because of its distributed,non-tamperable and inherent immutability features.However,the international cryptographic algorithm used in the blockchain has certain backdoor security risks.Based on the ...

Discrete choice, permutations, and reconstruction [PDF]
, 2018 In this paper we study the well-known family of Random Utility Models, developed over 50 years ago to codify rational user behavior in choosing one item from a finite set of options. In this setting each user draws i.i.d. from some distribution a utility

Provably Secure Covert Communication on Blockchain
Cryptography, 2018 Blockchain is a public open ledger that provides data integrity in a distributed manner. It is the underlying technology of cryptocurrencies and an increasing number of related applications, such as smart contracts. The open nature of blockchain together

Modeling Random Oracles Under Unpredictable Queries [PDF]
, 2016 In recent work, Bellare, Hoang, and Keelveedhi (CRYPTO 2013) introduced a new abstraction called Universal Computational Extractors (UCEs), and showed how they can replace random oracles (ROs) across a wide range of cryptosystems. We formulate a new framework, called Interactive Computational Extractors (ICEs), that extends UCEs by viewing them as ...

Efficient implementation of a CCA2-secure variant of McEliece using generalized Srivastava codes [PDF]
, 2012 International audienceIn this paper we present efficient implementations of McEliece variants using quasi-dyadic codes. We provide secure parameters for a classical McEliece encryption scheme based on quasi-dyadic generalized Srivastava codes, and ...

An Identity-Based Group Signature with Membership Revocation in the Standard Model [PDF]
, 2010 Group signatures allow group members to sign an arbitrary number\ud of messages on behalf of the group without revealing their\ud identity. Under certain circumstances the group manager holding a\ud tracing key can reveal the identity of the signer from ...

Universally Composable Oblivious Transfer with Low Communication
Applied Sciences, 2023 In this paper, a universally composable 1-out-of-N oblivious transfer protocol with low communication is built. This protocol obtained full simulation security based on the modulo learning with rounding (Mod-LWR) assumption.
