Improved on Identity-based quantum signature based on Bell states
Chang-Bin Wang, Shu-Mei Hsu, Hsiang Chang, and Jue-Sam Chou
Abstract
In 2020 Xin et al.proposed a new identity-based quantum signature based on Bell states scheme. By using a one-time padding (OTP) for both-side transfer operations like, "XOR", Hadamard H, and Y, they confirmed the security of the proposed scheme. However, after analyses, we found that the scheme cannot resist both the existing forgery attack and meaningful message attack. Therefore, we modified their scheme to include the required security, unforgeability, which is very important in quantum signature scheme.
