Abstract

The invention concerns a secure device for signature processing (10) interposed between a computerized device for storing documents (1), such as a computer, a PDA or a telephone for example, and a so-called peripheral device (5) such as a display screen, a printer, which is used to display to a user the content of the document whereof the digital signature is to be processed. In that configuration, the secure device (10) controls the peripheral in a signature processing mode, during which the non-secure storage device is not involved. Said device (10) further contains a digital port, a cryptographic unit, a video converter, an input and a display output.
