Title (EN) PERFORMING A KEY AGREEMENT RECOVERY PROCEDURE
(FR) EXÉCUTION D'UNE PROCÉDURE DE RÉCUPÉRATION D'ACCORD DE CLÉ
Abstract:
(EN) In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In certain implementations, the apparatus may perform a first key agreement procedure to determine a first shared secret for communicating with a second device. In one aspect, the first shared secret may be associated with first BI of the first device and a second BI of the second device. The apparatus may maintain a first correlation between the first shared secret and the second BI. The apparatus may perform a key agreement recovery procedure when it is determined that the second device does not maintain a second correlation between the first shared secret and the first BI.
(FR) Un aspect de l'invention concerne un procédé, un support lisible par ordinateur et un appareil. Dans certains modes de réalisation, l'appareil peut effectuer une première procédure d'accord de clé pour déterminer un premier secret partagé pour communiquer avec un second dispositif. Selon un aspect, le premier secret partagé peut être associé à un premier BI du premier dispositif et à un second BI du second dispositif. L'appareil peut maintenir une première corrélation entre le premier secret partagé et le second BI. L'appareil peut effectuer une procédure de récupération d'accord de clé lorsqu'il est déterminé que le second dispositif ne maintient pas une seconde corrélation entre le premier secret partagé et le premier BI.
