I'm looking for a practical example for creating an EC Ring Signature, very much at the level of detail as found in the CryptoNote Whitepaper but with O(1). I saw Short Linkable Ring Signatures for E-voting, E-cash and Attestation, but I'm not sure about two things:
Does it actually require a group manager or did I miss something? I need a solution where the signer sets-up the signature with no need for a trusted party.
The paper's Appendix A doesn't include a setup for the SLRS, and I don't trust myself with an implementation, I prefer something that went through some public review. I'm looking specifically for EC, not RSA.
I'd appreciate any help in either clarifying these issues about the above paper or alternatively suggesting some reviewed source for another implementation.
