Abstract
Official abstract text for this publication.
Disclosed is a method of rekeying radios for link layer encryption (LLE) in a radio network using a bifurcated crypto period. During a first portion of a first LLE crypto period during which a first LLE key (LEK) is used to LLE encrypt communications between a base station and mobile stations operating within a corresponding coverage area of the base station, a radio network communications device prevents individual ones of the mobile stations from requesting a second LEK to be used during a second LLE crypto period after the first LLE crypto period. During a second portion of the first LLE crypto period, the radio network communications device allows individual ones of the mobile stations to request the second LEK. A mobile station configured to operate in accordance with the bifurcated crypto period, and provide information regarding keys in its possession via an authentication response ISP, is also disclosed.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of rekeying radios for link layer encryption (LLE) in a radio network comprising a plurality of network locations, the method comprising, at a radio network communications device: during a first portion of a first LLE crypto period during which a first LLE key (LEK) is used to LLE encrypt inbound and outbound communications between a base station and mobile stations operating within a corresponding coverage area of the base station, preventing…
