Abstract
(EN)
Encryption is a common tool to achieve privacy of communication in networks whose lines are not physically protected. In most communication networks, however, having a sender S send an encrypted message to a recipient R does not hide the very fact that S has sent a message to R, and this may in itself constitute valuable information that the parties would rather keep confidential. There is described a transmission method that (1) keeps the identities of senders and receivers confidential, but (2) can trace senders and receivers under certain given circumstances.
(FR)
Le cryptage est un moyen usuel d'assurer la confidentialité des communications dans les réseaux dont les lignes ne sont pas l'objet d'une protection physique. Cependant, dans la plupart des réseaux de télécommunications le fait qu'un expéditeur S envoie un message crypté à un destinataire R ne dissimule pas le fait même de la transmission dudit message qui peut constituer en lui-même une information que les parties souhaiteraient maintenir confidentielles. La présente invention porte sur une technique de transmission (1) maintenant confidentielles les identités de l'expéditeur et du destinataire, mais permettant de pister ces derniers dans certaines circonstances.
