Abstract :
A content extraction signature can intercept a signature of primary message and do without interacting with signer. A new ED-CES scheme based on the batch signature is proposed. The proposed scheme introduces two independent PKG to solve the hidden secure trouble that the single PKG can impersonate the signers to forge their signatures. We also prove that our ED-CES scheme is correctness and unforgeability under the GDH assumption and identity attack.
