Traceable Policy-Based Signatures and Instantiation from Lattices
Yanhong Xu, Reihaneh Safavi-Naini, Khoa Nguyen +1
Policy-based signatures (PBS) were proposed by Bellare and Fuchsbauer (PKC 2014) to allow an {\em authorized} member of an organization to sign a message on behalf of the organizat…
Provably Secure Group Signature Schemes from Code-Based Assumptions
Martianus Frederic Ezerman, Hyung Tae Lee, San Ling +2
We solve an open question in code-based cryptography by introducing two provably secure group signature schemes from code-based assumptions. Our basic scheme satisfies the CPA-anon…
Accountable Tracing Signatures from Lattices
San Ling, Khoa Nguyen, Huaxiong Wang +1
Group signatures allow users of a group to sign messages anonymously in the name of the group, while incorporating a tracing mechanism to revoke anonymity and identify the signer o…
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…
