Permutation-Based Hash Chains with Application to Password Hashing
IACR Transactions on Symmetric CryptologyHash chain based password systems are a useful way to guarantee authentication with one-time passwords. The core idea dates back to Lamport, and is specified in RFC 1760 as S/Key. At CCS 2017, Kogan et al.

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 ...

Correcting Subverted Random Oracles
The random oracle methodology has proven to be a powerful tool for designing and reasoning about cryptographic schemes. In this paper, we focus on the basic problem of correcting faulty or adversarially corrupted random oracles, so that they can be confidently applied for such cryptographic purposes. We prove that a simple construction can transform a

Prikladnaya Diskretnaya MatematikaThe random oracle model is an instrument used for proving that protocol has no structural flaws when settling with standard hash properties is impossible or fairly difficult. In practice, however, random oracles must be instantiated with some specific hash functions that are not random oracles.

Short Signatures Without Random Oracles [PDF]
, 2004 We describe a short signature scheme which is existentially unforgeable under a chosen message attack without using random oracles. The security of our scheme depends on a new complexity assumption we call the Strong Diffie-Hellman assumption. This assumption has similar properties to the Strong RSA assumption, hence the name. Strong RSA was previously

The (trans)national Russian religious imagination in exile: Iulia de Beausobre (1893‐1977)
Modern Theology, EarlyView.Abstract The article offers a case study of how Russian Orthodox who migrated from the Soviet Union after the Bolshevik Revolution of 1917 reimagined their religious identity and their church in a transnational setting. Iulia de Beausobre (1893‐1977) was a Russian aristocrat who fell victim to the Stalinist purges but survived the Soviet prison system ...

Evolutionary legacies structure the geography of seagrass traits across the world's oceans
New Phytologist, EarlyView.Summary Traits modulate species' ability to track shifts in climate, yet the extent to which traits have been shaped by the contemporary environment and/or historical processes remains poorly understood. Here, we fill this gap for the world's seagrasses, habitat‐forming species that provide critical ecosystem services.

Variable selection via thresholding
Scandinavian Journal of Statistics, EarlyView.Abstract Variable selection comprises an important step in many modern statistical inference procedures. In the regression setting, when estimators cannot shrink irrelevant signals to zero, covariates without relationships to the response often manifest small but nonzero regression coefficients.
