CA 2511335

This present invention provides users with secure transparent electronic communication, allowing them to send and receive encrypted and/or signed messages with little or no user involvement. In various embodiments, the present invention provides a user with e-mail security via automated hierarchical techniques for transparently sending and receiving secure messages, and lowers the burden on administrators. The present invention can include a server in a local network that acts as a proxy between a user and an open communications network, thereby providing transparent transmission and receipt of secure messages for the user. This could be used for sending and receiving secure e-mail or for securing instant messaging (IM). A server according to the present invention can intercept unsecured messages from a user, automatically transform those messages into secured messages, and transmit those secure messages to the intended recipients.

Cette invention permet d'assurer aux utilisateurs des communications électroniques transparentes sécurisées, leur permettant d'envoyer et de recevoir des messages codés et/ou signés avec peu ou pas d'implication de l'utilisateur. Dans divers modes de réalisation, cette invention assure à l'utilisateur la sécurité du courrier électronique grâce à des techniques hiérarchiques automatisées pour l'envoi et la réception en mode transparent de messages sécurisés et elle réduit la charge des administrateurs. Cette invention peut utiliser un serveur dans un réseau local qui sert de procuration entre un utilisateur et un réseau de communication ouvert, assurant à l'utilisateur la transmission et la réception transparentes de messages sécurisés. Cette invention peut servir à envoyer et à recevoir des courriers électroniques sécurisés ou à sécuriser des messages instantanés (IM). Un tel serveur peut intercepter les messages non sécurisés provenant d'un utilisateur, transformer automatiquement ces messages en messages sécurisés et transmettre les messages ainsi sécurisés aux destinataires souhaités.
