Abstract
A method and arrangement for distributing a security policy to a communication terminal having an association with a home communication network, but being present in a visited communication network. The home communication network generates its own preferred security policy Ph and the visited communication network generates its own preferred security policy Pv. A communication network entity in the visited communication network combines the security policies and selects security algorithms and/or functions to apply from the combined security policy. By generating security policy vectors of both networks and combining them before the security algorithms are selected, both networks are able to influence the selection without requiring the use of signaling messages.
