Abstract
Certificateless hybrid signcryption is a newly cryptosystem that plays a great role in some storage-constrained networks when confidentiality and authenticity are needed simultaneously. Now considering almost all certificateless signcryption schemes that have been proposed in the literature cannot effectively against the public-key-replacement attacks. In this paper, we proposed a hybrid signcryption scheme in the certificateless setting to fill this security gaps, and its security has been verified to achieve the confidentiality and unforgeability in random oracle model. Moreover, performance analysis shows the proposed scheme is efficient and practical.
