In recent years, oblivious pseudorandom functions (OPRFs) have become a ubiquitous
primitive used in cryptographic protocols and privacy-preserving technologies. The growing …

Abstract In a Password-Protected Secret Sharing (PPSS) scheme with parameters (t,
n)(formalized by Bagherzandi et al.[2]), a user Alice stores secret information among n …

PPSS is a central primitive introduced by Bagherzandi et al.[2] which allows a user to store a
secret among n servers such that the user can later reconstruct the secret with the sole …

Recent years have seen the emergence of practical advanced cryptographic tools that not
only protect data privacy and authenticity, but also allow for jointly processing data from …

Token-based authentication is commonly used to enable a single-sign-on experience on the
web, in mobile applications and on enterprise networks using a wide range of open …

Traditional construction supply chains suffer from extra delays, costs and information
wastages due to information intermediaries. Blockchain, a decentralized infrastructure, can …

Abstract The proliferation of Decentralised Finance (DeFi) and Decentralised Autonomous
Organisations (DAO), which in current form are exposed to front-running of token …

Decentralized Finance (DeFi) is a new paradigm in the creation, distribution, and utilization
of financial services via the integration of blockchain technology. Our research conducts a …

We present TOPPSS, the most efficient Password-Protected Secret Sharing (PPSS) scheme
to date. A (t, n)-threshold PPSS, introduced by Bagherzandi et al. 4, allows a user to share a …

Single Sign-On (SSO) is becoming an increasingly popular authentication method for users
that leverages a trusted Identity Provider (IdP) to bootstrap secure authentication tokens from …
