An Efficient Lattice Based Linkable Ring Signature Scheme With

An Efficient Lattice Based Linkable Ring Signature Scheme With In this paper, we propose a novel lattice based linkable ring signature scheme based on the borromean ring signature. in our scheme, to avoid the extra overhead caused by reject sampling that used in the existing schemes, we use an exact indistinguishable distribution to replace it. In this paper, we propose a novel lattice based linkable ring signature scheme based on the borromean ring signature. in our scheme, to avoid the extra overhead caused by reject.

Github Apuljain Linkable Ring Signature This work proposes a fiat shamir linkable ring lattice based signature scheme, building on yuen et al. ‘s generic ring signature. it converts the mlwe based Σ protocol into a linkable ring signature through the fiat shamir transformation, employing rejection sampling to avoid private key leakage. In this paper, we present a lattice based linkable ring signature scheme designed to withstand quantum era adversaries. the framework relies on exact and efficient zero knowledge proofs, and employs a weak pseudorandom function (wprf) to enable linkability. Aiming at the large signature size and low computational efficiency of the current post quantum trs schemes, this paper proposes an efficient lattice based trs scheme in the scenarios of small and medium sized rings (ring size is 5 to 2000) based on the popular module short integer solution (m−sis) and module learning with errors (m−lwe. Finally, the proposed scheme and other five latest lattice based lrs schemes are implemented, which shows that under the same security level, the proposed scheme has higher signature generation and verification efficiency as well as shorter signature size compared with other five lrs schemes.

Raptor is presented, the first practical lattice based (linkable) ring signature scheme with implementation and it is shown that the latter construction, called raptor, is almost as efficient as the classical rst ring signatures and thus may be of practical interest. An efficient lattice based linkable ring signature scheme with scalability to multiple layer. This paper presents a new blockchain scheme using a linkable ring signature algorithm based on lattice cryptography. this scheme counters quantum attacks on blo. Ring signatures enable a user to sign messages on behalf of an arbitrary set of users, called the ring. the signer anonymity property guarantees that the signature does not reveal which member of the ring signed the message.
