A quantum secure novel identity-based signcryption scheme based on group ring

This study proposes a novel signcryption scheme based on the algebraic structure of the group ring and proves its provable security, and shows that the security of the scheme relies on the intractability of two hard problems, i.e., bilinear Diffie–Hellman inversion in group ring and bilinear strong Diffie–Hellman assum...
