Cryptanalysis of a Pairing-free Certificateless Signcryption scheme

Signcryption is a very useful cryptographic primitive that aims to achieve authentication and confidentiality in an efficient manner. We cryptanalyze the signcryption scheme of Wei and Ma (2019) which is claimed to be secure. Further, we propose a corresponding modification to show how their signcry...
