Abstract
The invention provides for secure end-to-end user authentication by a remote server communicating with a communication device. The communication device further communicates with an authentication device, which provides a user authentication message to the communication device for forwarding to the remote server. The authentication device comprises a data store for storing user authentication credentials. A user authentication processor performs a local authentication of a user of the authentication device in response to a user input. An authentication processor generates the authentication message if the user authentication is valid. The authentication processor implements a cryptographic function based on the user authentication credentials. A transmitter then transmits the authentication message to the at least one communication device.
