Title
(EN) WEB-BASED DELIVERY OF SECURE E-MAIL MESSAGES
(FR) ACHEMINEMENT SECURISE DE MESSAGES ELECTRONIQUES SUR INTERNET
Abstract
(EN)
An electronic document delivery system that enables exchange of digitally signed and public key encrypted packages without requiring pre-installed specialized public key security software applications on recipient's computer. A URL identifying such a package is sent to the recipient by e-mail. Upon submission of the URL through the World Wide Web, computer instructions in the form of an applet, for example, are sent to the recipient to effect retrieval and processing of the package. Such processing can include decrypting one or more parts of the package and verification of a signature of the package.
(FR)
L'invention porte sur un système d'acheminement de documents électroniques, qui permet d'échanger des blocs comportant une signature numérique et un chiffrement à clé publique, sans nécessité de préinstaller sur l'ordinateur destinataire des logiciels de protection à clé publique spécialisés. Un URL d'identification du bloc est envoyé à l'ordinateur destinataire par courrier électronique. Une fois l'URL reçu par Internet, des instructions informatiques sont ensuite transmises à l'ordinateur destinataire, sous forme d'un applet, par exemple, pour effectuer l'extraction et le traitement du bloc. Ce traitement peut comprendre le décryptage d'une ou plusieurs parties du bloc et la vérification d'une signature associée au bloc.
