A Practical Identity-based Signcryption Scheme
Huiyan Chen, Yong Li, Jinping Ren · 2013
Abstract. In this paper, we give a new identity-based signcryption scheme based on bilinear pairings. It is secure against adaptive chosen ciphertext and identity attack in the random oracle, with the assumption that a variant of the Bilinear Diffie-Hellman problem is hard to decide. It produces shorter length ciphertext than the Libert-Quisquater signcryption scheme for the same plaintext and adapts to the band-constrained scenario very well.
