- The paper provides a formal rigorous security model for accountable ring signatures. It also provides highly efficient constructions of ring and dynamic groups signatures, which are central cryptographic constructs. The constructions yield signatures of logarithmic size in the size of the ring/group and their security is based solely on standard intractability assumptions. The efficiency of the constructions outperforms that of existing ones. Our model has been adopted by many subsequent constructions and our constructions have been used in various applications.
