“…In 2018, Tsaur et al [19] presented an efficient PBS scheme and analyzed the security of the scheme based on the assumption of ECDLP. In 2019, Cui et al [7] proposed a restrictive PBS scheme that does not use bilinear pairings and improves computing efficiency, but they did not show the security proofs.…”

Blind signature is a special type of digital signature, the signer cannot see the specific content signed. However, blindness may cause users to abuse their rights. Partial blind signature allows the signer to embed pre-negotiated public information in the blind signature without losing blindness, which can prevent users from abusing their rights. Islam et al. [10] presented an identity-based partial blind signature scheme and claimed that it is provable secure. However, in this paper we proved that the scheme [10] is vulnerable against the tampering attacks with public information. We then proposed a new identity-based partial blind signature scheme, showed the security proofs under the assumption that the elliptic curve discrete logarithm problem (ECDLP) is difficult. The new scheme does not use pairing operations and enjoys less computation cost.

Blind signatures are well-studied building blocks of cryptography, originally designed to enable anonymity in electronic voting and digital banking. Identity-based signature were introduced by Shamir in 1984 and gave an alternative to prominent Public Key Infrastructure. An identity-based blind signature (IDBS) allows any user to interact directly with the signer without any prior interaction with a trusted authority. The first IDBS has been proposed in 2002 and several schemes were proposed since then. Seeking for a full comparison of these primitives, we propose a survey on IDBS and list all such primitives that seems to maintain some security. We also classify their security assumptions based on the existing security expectation that have not been formalized yet in the literature. Moreover, we empirically evaluate the complexity of all the operations used in those schemes with modern cryptographic libraries. This allows us to perform a realistic evaluation of their practical complexities. Hence, we can compare all schemes in terms of complexity and signature size.
