Abstract

CAICEDO, Oscar; DE LA CRUZ, Edgar  and  TAIMAL, Geovanni. Security middleware for IMS-WLAN interworking. Rev.fac.ing.univ. Antioquia [online]. 2010, n.56, pp.193-202. ISSN 0120-6230.

The 3GPP proposes security architecture for Interworking WLAN-3GPP. However, it presents inefficiencies in the authentication procedure, which bring a greater consumption of radio resources, processing on the devices and delayed authentication. Due to previous reasons, we propose a security middleware that reduces the steps in the authentication of the WLAN-3GPP interworking and ensures the SIP signaling between the user equipment and the first entry point to the IMS network (P-CSCF).

Keywords : Authentication; confidentiality; IMS; integrity; interworking; security; WLAN.
