Abstract :

A blind signature scheme allows a receiver to obtain a signature on a message such that both the message and the resulting signature remain unknown to the signer. We refer the readers for a formal definition of a blind signature scheme, which should bear the properties of verifiability, unlinkability and unforgeability. Blind signature scheme, where the restrictiveness property is incorporated into the blind signature scheme such that the message being signed must contain encoded information. As the name suggests, this property restricts the user in the blind signature scheme to embed some account-related secret information into what is being signed by the bank, such that this secret can be recovered by the bank to identify a user if and only if he double-spends. The restrictiveness property is essentially the guarantee for traceability in the restrictive blind signature systems. In order to maintain security of the network against attacks and the fairness among clients, the home server manager may control the access of each client by issuing tickets based on the misbehavior history of the client, which reflects the server manager’s confidence about the client to act properly. Ticket issuance occurs when the client initially attempts to access the network or when all previously issued tickets are depleted. The client needs to reveal his real ID to the server manager in order to obtain a ticket since the server manager has to ensure the authenticity of this client.
