Title (EN) MANAGING SECURITY CONTEXTS AND PERFORMING KEY DERIVATION AT HANDOVER IN A WIRELESS COMMUNICATION SYSTEM
(FR) GESTION DE CONTEXTES DE SÉCURITÉ ET RÉALISATION D'UNE DÉRIVATION DE CLÉ LORS D'UN TRANSFERT INTERCELLULAIRE DANS UN SYSTÈME DE COMMUNICATIONS SANS FIL
Abstract:
(EN) There is provided a method for determining a security context for communication between a wireless device and a target network node at handover. The method comprises obtaining (S1) information representative of the type of Radio Access Technology, also referred to as RAT type, of the target network node, and deriving and/or determining (S2) the security context at least partly based on the information representative of the RAT type.
(FR) L'invention concerne un procédé permettant de déterminer un contexte de sécurité pour une communication entre un dispositif sans fil et un nœud de réseau cible lors d'un transfert. Le procédé comprend l'obtention (S1) d'informations représentatives du type de technologie d'accès radio (RAT) du nœud de réseau cible, et la dérivation et/ou la détermination (S2) du contexte de sécurité au moins en partie sur la base des informations représentatives du type de RAT.
