In the last decades, several signcryption schemes have been developed for different privacy-enhancing purposes. In this paper, we propose a new privacy-enhancing group signcryption schemethat provides: unforgeability, confidentiality, ciphertext and sender anonymity, traceability, unlinkability,exculpability, coalition-resistance, and unforgeable tracing verification. It is important to notice that theproposed scheme allows a signer to anonymously signcrypt a message on the group’s behalf (i.e., sender’sanonymity). The security analysis of the scheme is also provided. Our proposal is proven to be stronglyexistentially unforgeable under an adaptive chosen message attack, indistinguishable under an adaptivechosen ciphertext attack, and to provide ciphertext anonymity under an adaptive chosen ciphertext attack.Furthermore, the scheme is extended to work in a multi-receiver scenario, where an authorized group ofreceivers is able to unsigncrypt the ciphertext. The experimental results show that our scheme is efficienteven on computationally restricted devices and can be therefore used in many IoT applications. TheSigncryptprotocol on smart cards takes less than 1 s (including communication overhead). The timeof theUnsigncryptprotocol on current ARM devices is negligible (less than 40 ms).
