New Constructions of Short Signatures in the Standard Model
Leyou Zhang, Qing Wu, Yupu Hu · Journal of Software · 2011
To meet the need s in low-bandwidth communication, low-storage and less computation environments , a new technique is introduced to construct short signature in the standard model. The new short signature scheme is constructed based on the bilinear pairing and has short public parameters . In addition, the size of the signature achieves 160 bits. U nder the n -Exponent Computational Diffie-Hellman Problem( n -CDH), the new scheme is provable security. Finally, we also give the application of the new scheme by constructing the short identity-based signature and threshold signatures.
