Abstract
A method for digitally signing a document, a secure device, and a computer program product for implementing the method. The method employs a secure device which is protected against malicious software or malware and is adapted to establish a secure connection to a recipient via a host. The method includes: connecting to a terminal; accessing the contents of a document received by the secure device; instructing at the secure device to communicate the accessed contents to an output device other than the terminal such that the contents can be verified by a user; ascertaining at the secure device a command received to digitally sign the document; executing at the secure device the ascertained command; and instructing to send a digitally signed document to a recipient over a connection established via the host connected to a telecommunication network.
