Abstract: Blockchain technology provides efficient and secure solutions to various online activities by utilizing a wide range of cryptographic tools. In this article, we survey the existing literature on post-quantum secure digital signatures that possess exotic advanced features and that are crucial cryptographic tools used in the blockchain ecosystem for (1) account management, (2) consensus efficiency, (3) empowering scriptless blockchain, and (4) privacy. The exotic signatures that we particularly focus on in this work are the following: multi-/aggregate, threshold, adaptor, blind, and ring signatures. Herein the term ”exotic” refers to signatures with properties that are not just beyond the norm for signatures, e.g., unforgeability, but also imbue new forms of functionalities. Our treatment of such exotic signatures includes discussions on existing challenges and future research directions in the post-quantum space. We hope that this article will help to foster further research to make post-quantum cryptography more accessible so that blockchain systems can be made ready in advance of the approaching quantum threats.

Abstract: DualRing is a novel generic construction introduced by Yuen et al. (CRYPTO’21), which can transform a special kind of (Type-T*) canonical identification scheme to a ring signature scheme. Compared with the classical approaches, this method can get a shorter signature. In this paper, we construct a new middle-product learning with errors (MPLWE)-based ring signature scheme by using this framework. Specifically, we propose a new MPLWE-based identification scheme, which is compatible with the DualRing, then we obtain a ring signature scheme by using DualRing framework. We also show how to achieve linkability from this ring signature by using a collision resistant hash function. In the end, we provide available parameter options for our (linkable) ring signature scheme. Under these parameters, the signature size of our linkable ring signature is $2-40 \\times $ shorter (depending on the ring size) than the previous MPLWE-based scheme by Das et al. (Africacrypt’19).

Abstract: A ring signature scheme is a group signature scheme but with no group manager to setup a group or revoke a signer's identity. It allows members of a group to sign messages such that the resulting signatures do not reveal the identities of the group members who actually created these signatures (anonymity) and no one can tell if two signatures are created by the same signer (unlinkability). Furthermore, the formation of a group is spontaneous. Diversion group members (non-signers) can be totally unaware of being conscripted to the group. The notion of linkable ring signature, introduced by Liu et al. in 2004, also provides signer anonymity and spontaneity, but at the same time, allows anyone to determine whether two signatures have been issued by the same group member (linkability). In this paper, we propose a suite of enhanced security models and show that they capture stronger notions of signer anonymity and linkability than the original ones proposed by Liu et al. in 2004. We also propose a generic approach for constructing a linkable ring signature scheme. The generic approach leads us to the construction of two efficient polynomial-structured schemes and one type-restricted separable scheme. The separable scheme allows group members to have different sets of DL (discrete logarithm) domain parameters. All schemes are shown secure under the enhanced security models defined in this paper.
