Exploiting an HMAC-SHA-1 Optimization to Speed up PBKDF2 [PDF]
IEEE Transactions on Dependable and Secure Computing, 2020 PBKDF2 [1] is a well-known password-based key derivation function. In order to slow attackers down, PBKDF2 introduces CPU-intensive operations based on an iterated pseudorandom function (in our case HMAC-SHA-1). If we are able to speed up a SHA-1 or an HMAC implementation, we are able to speed up PBKDF2-HMAC-SHA-1.

IACR Cryptol. ePrint Arch., 2020 The SHA-1 hash function was designed in 1995 and has been widely used during two decades. A theoretical collision attack was first proposed in 2004 [29], but due to its high complexity it was only implemented in practice in 2017, using a large GPU cluster [23].

Second-Preimage Analysis of Reduced SHA-1 [PDF]
, 2010 Many applications using cryptographic hash functions do not require collision resistance, but some kind of preimage resistance. That's also the reason why the widely used SHA-1 continues to be recommended in all applications except digital signatures after 2010.

New Preimage Attacks against Reduced SHA-1 [PDF]
, 2012 This paper shows preimage attacks against reduced SHA-1 up to 57 steps. The best previous attack has been presented at CRYPTO 2009 and was for 48 steps finding a two-block preimage with incorrect padding at the cost of $$2^{159.3}$$ evaluations of the compression function.

A Two‐Stage Questionnaire and Actigraphy Screening for iRBD in a Multicenter Retrospective Cohort
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Isolated rapid‐eye‐movement sleep behavior disorder is a prodromal marker of synucleinopathies. However, most cases remain undiagnosed due to the insufficient predictive value of questionnaires and limited access to confirmatory video‐polysomnography. We assessed a two‐stage screening strategy combining a brief questionnaire on rapid‐

On the Cost of ASIC Hardware Crackers: A SHA-1 Case Study [PDF]
, 2021 In February 2017, the SHA-1 hashing algorithm was practically broken using an identical-prefix collision attack implemented on a GPU cluster, and in January 2020 a chosen-prefix collision was first computed with practical implications on various security protocols.
