Abstract
Methods and systems are disclosed for a digital signature system using scalable servers. The system includes scalable frontend servers to communicate with applications servers and scalable backend servers to communicate with remote security devices. When a user, and their remote security device(s), is registered with the system, the remote security device(s) is/are assigned to a backend server. A total public key is generated by cryptographically embedding the unique identifier of the assigned backend server into a combined public key associated with the remote security device(s). When a signature request including the total public key is received at the frontend server, the unique identifier is extracted and the signature request is forwarded to the backend server that corresponds with the unique identifier.
