Ring signature allows specifying a set of possible signers without revealing which member actually produces the signature. This concept was first formalized in 2001 by Rivest, Shamir and Tauman. In this paper, we review the state-of-the-art of ring signature, summarize the study of ring signature schemes in the literature and investigate their relationships with other existing cryptographic schemes. We also describe a large number of extensions, modifications and applications of ring signatures after the original version of this work. Some problems in the study of this field were presented as well. Finally, we discuss a number of interesting open problems and point out the possible future work.

“…They combined it with a combinatorial function to construct an effective threshold ring signature scheme, where some members of the ring can sign on behalf of all users in the ring as long as they reach a specified threshold, which introduces the idea of fair splitting and is demonstrably safe in a stochastic prediction model, but when the number of signers is large, the efficiency of this scheme is low. The threshold ring signature scheme proposed by Toshiyuki et al 17 has higher efficiency in the case of a large number of signers, but it has security problems. Chung et al proposed an identity-based threshold ring signature scheme using bilinear pair mappings.…”

“…Identity privacy protection techniques based on ring signatures and threshold ring signatures have been extensively studied. [17][18][19] However, the existing schemes have many elliptic curve point additions, large power multiplication and even bilinear mappings that are difficult to apply to wireless terminals' computing environment.…”

Blockchain has decentralization characteristics and requires more targeted security schemes to protect user privacy. In contrast, existing signature schemes have many high-complexity operations and impose an enormous computational burden on wireless nodes. This article proposes a light-weighted identity privacy scheme for blockchain-based on edge computing. We construct linkable identity privacy and non-linkable identity privacy, which can resist collusion attacks while virtually guaranteeing blockchain nodes' identity privacy. Since edge computing offloads heavily, the proposed scheme has lower computational complexity than the existing techniques.

Polymer samples in the jigs begins to protrude when the heat is turned up when we measure the rheological characteristics of polymer melts using rotationaltype rheometers, such as parallel and cone-and-plate types. To clarify the effects of this protruding part on the obtained rheological data, we tried to evaluate the rotational-type rheometer by a non-isothermal viscoelastic flow simulation using the finite element method. The multiple mode Phan-Thien Tanner (PTT) model was employed as the constitutive equation. As a result, the shear viscosity in the steady state increases with the size of the protruding part of the polymer melt specimen at the same shear rate in case with a parallel plate and a cone-and-plate type rheomters. In contrast, the deviation of the primary normal stress difference between the estimated value from the simulation results and the data from the PTT model is almost independent of the size of the protruding part with the cone-and-plate type rheometer. In addition, the deviations of the primary normal stress difference with a parallel plate rheometer increase with the protruding part size. However, these deviations are smaller than those of shear viscosity.
