Title (EN) NETWORK DEVICE AND TRUSTED THIRD PARTY DEVICE
(FR) DISPOSITIF DE RÉSEAU ET DISPOSITIF TIERS DE CONFIANCE
Abstract:
(EN) A first network node (100; 200) is configured to, - compute a first shared key (245) to protect confidentiality from the first identity of the second network node and the local key material to protect confidentiality of the first network node, - compute a second shared key (246) to protect integrity from the second identity of the second network node and the local key material to protect integrity of the first network node, - encrypt a message using the first shared key, and - compute a first message authentication code over the message using the second shared key.
(FR) L'invention concerne un premier nœud de réseau (100 200) qui est configuré pour, -calculer une première clé partagée (245) afin de protéger la confidentialité de la première identité du second nœud de réseau et de l'élément de clé local afin de protéger la confidentialité du premier nœud de réseau, -calculer une seconde clé partagée (246) afin de protéger l'intégrité de la seconde identité du second nœud de réseau et de l'élément de clé local afin de protéger l'intégrité du premier nœud de réseau, - chiffrer un message à l'aide de la première clé partagée, et - calculer un premier code d'authentification de message sur le message à l'aide de la seconde clé partagée.
