Exploiting an HMAC-SHA-1 Optimization to Speed up PBKDF2 [PDF]

IEEE Transactions on Dependable and Secure Computing, 2018
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.

Locality preserving binary face representations using auto‐encoders

IET Biometrics, Volume 11, Issue 5, Page 445-458, September 2022., 2022
Abstract Crypto‐biometric schemes, such as fuzzy commitment, require binary sources. A novel approach to binarising biometric data using Deep Neural Networks applied to facial biometric data is introduced. The binary representations are evaluated on the MOBIO and the Labelled Faces in the Wild databases, where their biometric recognition performance ...

NSSIA: A New Self‐Sovereign Identity Scheme with Accountability

Security and Communication Networks, Volume 2022, Issue 1, 2022., 2022
Self‐sovereign identity (SSI) is a new distributed method for identity management, commonly used to address the problem that users are lack of control over their identities. However, the excessive pursuit of self‐sovereignty in the most existing SSI schemes hinders sanctions against attackers.

Security Analysis and Bypass User Authentication Bound to Device of Windows Hello in the Wild

Security and Communication Networks, Volume 2021, Issue 1, 2021., 2021
Windows Hello is a Fast IDentity Online‐ (FIDO‐) based new login system for Windows 10, which provides a single sign‐on (SSO) service to diverse online applications. Hardware protection is essential for Window Hello’s security. This paper aims to examine the security of Windows Hello on a device where hardware protection is unavailable.
