Ring signatures are cryptographic protocols designed to allow any member of a group to produce a signature on behalf of the group, without revealing the individual signer's identity.  ...  We review the privacy and security properties offered by the scheme we have constructed, and compare its efficiency with other commonly suggested approaches to privacy on the blockchain.  ...  Finally, thanks to the University of Manchester, UCL, Yorkshire Ladies' Trust, and countless others for their generous grants over the years, without which this MSc would not have been possible.  ...

In the paper, we also show that the signature maintains the anonymity of participating signers unconditionally and is existential unforgeable against chosen message attacks in the random oracle model.  ...  We present a threshold ring signature scheme (spontaneous anonymous threshold signature scheme) that allows the use of both RSAbased and DL-based public keys at the same time.  ...  Besides, B also simulates E's point of view by constructing the random oracle G and the signing oracle SO. We first describe the construction of the signing oracle SO.  ...

Our proposed schemes fit with ring trapdoor functions introduced by Brakerski and Kalai [18] , and we obtain the first lattice-based ring signature scheme in the random oracle model.  ...  Moreover, motivated by Boyen's work [16], our second construction in the standard model achieves in stronger security definitions and shorter signatures than Brakeski-Kalai scheme.  ...  To the best of author's knowledge, our constructions consist of the first lattice-based ring signature scheme in the random oracle model and achieve in stronger security definitions and shorter signatures  ...

Recently, Bender, et al. proposed two new anonymity definitions of ring signature schemes which are stronger than the previous definitions, that are called anonymity against attribution attacks/full key  ...  In addition, ring signature schemes have two levels of definitions for unforgeability definitions, i.e., existential unforgeability and strong existential unforgeability.  ...  Universally Composable Construction without Random Oracles In this section, we show concrete constructions of ring signature which securely realize F (uf ,anon) rSIG .  ...

Finally, we construct a novel convertible ring signature scheme with collusion resistance and prove the security of the scheme in the presented security model.  ...  A convertible ring signature scheme is an extension of a ring signature scheme that authenticates a signer and proves that a real signer and no one else generated a ring signature.  ...  at random, and then outputs secret internal information, ω σ and a public ring signature, σ.  ...
