Band‐Pass Filtering With High‐Dimensional Time Series. A Synthetic Indicator of the Medium‐to‐Long Run Component of Growth

Journal of Time Series Analysis, EarlyView.
ABSTRACT The paper deals with the construction of a synthetic indicator of economic growth, obtained by projecting a quarterly measure of aggregate economic activity, namely gross domestic product (GDP), into the space spanned by a finite number of smooth principal components, representative of the medium‐to‐long‐run component of economic growth of a ...

Multi-User Security Bound for Mixed Filter Permutators in the Random Oracle Model

IACR Transactions on Symmetric Cryptology
At Eurocrypt’16, Méaux et al. designed a construction for symmetric ciphers that can be efficiently evaluated with Fully Homomorphic Encryption, dubbed Filter Permutator. They also specify FLIP, a family of Filter Permutators.

Breaking Verifiable Delay Functions in the Random Oracle Model [PDF]

This work resolves the open problem of whether verifiable delay functions (VDFs) can be constructed in the random oracle model.A VDF is a cryptographic primitive that requires a long time to compute (even with parallelization), but produces a unique ...

Penalized Convex Estimation in Dynamic Location Models

Journal of Time Series Analysis, EarlyView.
ABSTRACT This paper studies L1$$ {L}^1 $$‐penalized estimation for location models yt=mt+ϵt$$ {y}_t={m}_t+{\epsilon}_t $$, where mt$$ {m}_t $$ is defined by a possibly non‐Markovian recursion and ϵt$$ {\epsilon}_t $$ is a martingale difference sequence with possibly time‐varying conditional variance.

How to Construct Cryptosystems and Hash Functions in Weakened Random Oracle Models [PDF]

, 2009
In this paper, we discuss how to construct secure cryptosystems and secure hash functions in weakened random oracle models. ~~~~The weakened random oracle model ($\wrom$), which was introduced by Numayama et al.

Equilibrium Reward for Liquidity Providers in Automated Market Makers

Mathematical Finance, EarlyView.
ABSTRACT We find the equilibrium contract that an automated market maker (AMM) offers to their strategic liquidity providers (LPs) in order to maximize the order flow that gets processed by the venue. Our model is formulated as a leader–follower stochastic game, where the venue is the leader and a representative LP is the follower.

Becoming Dostoevsky (how Rowan Williams opens up Bakhtin)

Modern Theology, EarlyView.
Abstract With the end of Communism in Russia, non‐materialist contexts were enthusiastically restored to Mikhail Bakhtin's globally famous ideas of carnival, dialogism, and polyphony. This essay surveys Rowan Williams's 2008 study Dostoevsky: Language, Faith + Fiction as a major contribution to this effort, concentrating on those general philosophical ...

Certificateless signature scheme without bilinear pairings

Tongxin xuebao, 2012
To solve the key escrow problem inherited in ID-based cryptography and the complex certificate management problem of traditional certification-based public key cryptosystem,Al-Riyami and Paterson proposed the novel concept of certificateless public key ...

Limits of Random Oracle in Secure Computation

, 2011
Random Oracles have proven to be extremely powerful constructs in cryptography and they can be used to realize several useful cryptographic primitives which are, otherwise, impossible in the plain model.
