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…
Non-malleable Coding for Arbitrary Varying Channels
Fuchun Lin, San Ling, Reihaneh Safavi-Naini +1
Non-malleable codes protect against an adversary who can tamper with the coded message by using a tampering function in a specified function family, guaranteeing that the tampering…
Leakage-Resilient Non-Malleable Secret Sharing in Non-compartmentalized Models
Fuchun Lin, Mahdi Cheraghchi, Venkatesan Guruswami +2
Non-malleable secret sharing was recently proposed by Goyal and Kumar in independent tampering and joint tampering models for threshold secret sharing (STOC18) and secret sharing w…
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…
