Non-Interactive Plaintext (In-)Equality Proofs and Group Signatures with Verifiable Controllable Linkability
[chapter]
2016
Lecture Notes in Computer Science
Group signatures are an important privacy-enhancing tool that allow to anonymously sign messages on behalf of a group. A recent feature for group signatures is controllable linkability, where a dedicated linking authority (LA) can determine whether two given signatures stem from the same signer without being able to identify the signer(s). Currently the linking authority is fully trusted, which is often not desirable. In this paper, we firstly introduce a generic technique for non-interactive
