Zero-Knowledge Password Policy Check from Lattices
Khoa Nguyen, Benjamin Hong Meng Tan, Huaxiong Wang
Passwords are ubiquitous and most commonly used to authenticate users when logging into online services. Using high entropy passwords is critical to prevent unauthorized access and…
Lattice-Based Group Signatures: Achieving Full Dynamicity (and Deniability) with Ease
San Ling, Khoa Nguyen, Huaxiong Wang +1
In this work, we provide the first lattice-based group signature that offers full dynamicity (i.e., users have the flexibility in joining and leaving the group), and thus, resolve…
Server-Aided Revocable Predicate Encryption: Formalization and Lattice-Based Instantiation
San Ling, Khoa Nguyen, Huaxiong Wang +1
Efficient user revocation is a necessary but challenging problem in many multi-user cryptosystems. Among known approaches, server-aided revocation yields a promising solution, beca…
Forward-Secure Group Signatures from Lattices
San Ling, Khoa Nguyen, Huaxiong Wang +1
Group signature is a fundamental cryptographic primitive, aiming to protect anonymity and ensure accountability of users. It allows group members to anonymously sign messages on be…
