Abstract
A method, apparatus and computer program product are provided to facilitate security in response to a handover from an initial network to a subsequent network, such as a handover between a packet-switched network and a circuit-switched network. The method, apparatus and computer program product may provide at least one security key for use in the subsequent network following handover from the initial network such that communications conducted via the subsequent network, including initial communications, may be secure. In order to provide at least one security key for use in the subsequent network, at least one security key of the initial network may be identified along with a nonce in response to a determination that a handover is to be made. The at least one security key of the subsequent network may then be determined based upon the at least one security key of the initial network and the nonce.
