Smart-card based password authentication has been the most widely used two-factor
authentication (2FA) mechanism for security-critical applications (eg, e-Health, smart grid …

Despite three decades of intensive research efforts, it remains an open question as to what
is the underlying distribution of user-generated passwords. In this paper, we make a …

Password authentication is the dominant form of access control for the Web and mobile
devices, and its practicality and ubiquity is unlikely to be replaced by other authentication …

This study provides an in-depth survey of quantum secure authentication and key
agreement protocols, investigating the dynamic landscape of cryptographic techniques …

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 …

We present two provably secure password-authenticated key exchange (PAKE) protocols
based on a commutative group action. To date the most important instantiation of isogeny …

Public-key encryption with keyword search (PEKS) does not provide trapdoor privacy, ie,
keyword information is leaked through trapdoors. To prevent this information leakage, public …

Abstract Public Key Encryption with Keyword Search (PEKS), introduced by Boneh et al. in
Eurocrypt'04, allows users to search encrypted documents on an untrusted server without …

Password-based authenticated key exchange () protocol, a widely used authentication
mechanism to realize secure communication, allows protocol participants to establish a high …

Textual passwords are perhaps the most prevalent mechanism for access control over the
Internet. Despite the fact that human-beings generally select passwords in a highly skewed …
