A decentralized, unchanging, and verifiable public ledger that can track the exchange of digital assets is provided by the blockchain. After Bitcoin brought out the blockchain, the blockchain is used in new fields such as smart cities and e-health, and plays a very important role. Although the decentralization of the blockchain makes the construction of digital currency possible, its open and transparent design also risks leaking user privacy. In order to fulfill the security needs of blockchain applications for privacy related information, the relevant researchers have recently done research on blockchain privacy protection challenges and posted corresponding protection technologies, a few of which have been also successfully implemented in several prevailing blockchain applications. In view of the blockchain privacy protection technology issues, this paper investigates the latest progress of blockchain privacy protection technology, conducts a comparative analysis, and summarizes at the end, so as to make an outlook on future trends.

Compared with other schemes, the ring signature scheme proposed in this paper has the characteristics of revocable anonymity. When malicious users publish false messages, we can find an effective algorithm to revoke anonymity, calculate the real signer identity in the ring signature members, and ensure the reliability and robustness of the ring signature system. Finally, the scheme is analyzed from the aspects of security and performance, The results show that the ring signature scheme with revocable anonymity in this paper is more secure, more efficient and lower operation cost.

“…The ring signature sizes in [4], [5] based on RSA accumulators is independent of the ring size. Most recently, ring signatures that rely on the post-quantum assumptions like hash-based [15], [16] multivariate [17], [18] and (one-time) latticebased [19], [20], [21], [22], [23] are introduced.…”

The increasing demand for secure and anonymous transactions raises the popularity of ring signatures, which is a digital signature scheme that allows identifying a group of possible signers without revealing the identity of the actual signer. This paper presents efficient supersingular isogeny-based ring signature and linkable ring signature schemes that will find potential applications in post-quantum technologies. We develop the ring signature scheme by applying the Fiat-Shamir transform on the sigma protocol for a ring which we obtain from the supersingular isogeny-based interactive zero-knowledge identification scheme by adopting the scheme for a ring. We also extend our ring signature protocol with an additional parameter, i.e., a tag that provides to detect if a signer issues two signatures concerning the same ring by preserving anonymity and linkable anonymity. The signature size of our ring signature protocols increases logarithmically in the size of the ring thanks to the Merkle trees. We show the security proofs and efficiency analyses of the protocols offered. Moreover, we provide the implementation results of the supersingular isogeny-based ring signature, which offers small signature sizes for NIST post-quantum security levels.
