An ID-based content extraction signatures without trusted party
Xinchun Yin, Shuying Ye, Ou Funa, Zhang Hailing · 2010
A content extraction signature can intercept a signature of primary message and dispense to alternate with signer. A ID-based signature scheme without a trusted party is proposed in this paper, the efficiency of this scheme is higher than the other ID-based content extraction signature. We also prove that our ID-CES scheme is correctness and un-forgeability, under the GDH assumption and ID attack.
