Abstract

Examples of this disclosure include a method performed by a wireless device for determining security keys. The method comprises, for each candidate primary secondary cell (PSCell) of a plurality of candidate PSCells for conditional addition or conditional change by the wireless device for dual connectivity, receiving, from a network node, a respective value associated with the candidate PSCell, wherein the value associated with the candidate PSCell is different to the value associated with at least one other candidate PSCell. The method also comprises determining, for each of at least one candidate PSCell of the plurality of candidate PSCells, a respective security key for communications between the wireless device and the candidate PSCell, wherein the respective security key is determined based on a master key and the respective value associated with the candidate PSCell.
