2008 International Symposium on Electronic Commerce and Security
Construction of Server-assisted Forward Secure Signature Using Bellare-Miner Scheme
August 03-August 05
ISBN: 978-0-7695-3258-5
In this paper, we propose two server-assisted forward secure signature schemes using Bellare-Miner Scheme. In the first scheme, the user (signer) can employ a server to help her to produce a signature. In the second scheme, the number of employed servers is increased to n, therefore, it is infeasible for an attacker to forge a valid signature if she can’t corrupt all servers and the signer. The both schemes maintain the forward secure property. Finally, we prove the proposed schemes are correct and forward secure.
