System and method for selection of security algorithms

摘要

There is described a method and apparatus for managing security for a connection between a user device and a communications network comprising at least one base station and a core network. In one embodiment, the method includes receiving at the core network security capability information for the user device connecting to the communications network. Security capability information for the base station is then obtained from memory or from the base station itself. The security capability information for the user device and the security capability information for the base station is then processed in the core network to select a security policy for a connection between the user device and the base station and the selected security policy is transmitted to the base station.

1. A method of managing security for a connection between a user device and an Long Term Evolution (LTE) communications network comprising at least one Evolved Universal Terrestrial Radio Access Network (E-UTRAN) base station and a core network, the method comprising:
receiving, at the core network, security capability information for the user device connecting to the communications network; obtaining security capability information for one base station of the at least one base stations; processing, at the core network, the security capability information for the user device and the security capability information for the base station to select a plurality of preferred security policies for a connection between the user device and the base station; and transmitting the selected plurality of preferred security policies to the base station as a list of preferred security policies from which said base station can select a security policy, wherein the selected security policy relates to at least one of a Radio Resource Control (RRC), a User Plane (UP), and a Non-Access Stratum (NAS) security algorithm selection.
