Abstract:
1. A method comprising: providing, by a node or a network device, security in a network which comprises at least one node; checking a plurality of context-awareness parameters, the plurality of context-awareness parameters comprising at least one of a type of context parameter, a sender/receiver/user group parameter, a time-dependent context parameter, a communications mode parameter, and a location information parameter, setting at least one of a plurality of security parameters for a connection of a node to another node of the network depending on a result of the check of the plurality of context-awareness parameters, the setting of the at least one of the plurality of security parameters being based on a combination of context-awareness parameters that includes at least one of: a type of application executing on the node or the network device, a sender/receiver/user group, time information and communication mode used by the node or network device; representing context by the plurality of context-awareness parameters; obtaining a mapping between the context and the at least one security parameter; and establishing the connection between the node and the other node via a direct radio link, the node and the other node forming part of an ad-hoc network; wherein, when the other node receives a request for service from the node, the other node checks required security based on a context of the service, starts negotiating with the node about establishing the required security, and provides the service to the node after establishment of the required security.
