Cryptanalysis on 'An efficient identity-based proxy signcryption using lattice'
Abstract
In this note, we conduct a cryptanalysis of the paper published by Zhu et al. on Future Generation Computer Systems in 2021. We demonstrate that their quantum-resistant identity-based proxy signcryption scheme cannot achieve the confidentiality as they claimed.
