To provide secure communication for universal mobile telecommunications system (UMTS) Mobile Networks, authentication and key agreement (AKA) is carried out between the user and the home environment, and the authentication protocol is an important primitive for entity authentication and session keys. The current authentication protocol is giving a reasonable security level. However it is overloading...
The integration of the widely spread 3rd Generation (3G) Universal Mobile Telecommunication System (UMTS) with the Wireless Local Area Networks (WLANs) has recently attracted considerable attention. However, addressing seamless and transparent handoff during mobility between these networks is still the biggest challenge to overcome. This paper evaluates the components of the handoff delay for the...
Mobile IP is one of the popular mobility solution and a viable candidate for the Beyond 3rd Generation (B3G) networks such as the integrated 3rd Generation Universal Mobile Telecommunications System (UMTS) and the Wireless Local Area Networks (WLANs). Mobile IP has many configuration and enhancements that are proposed by IETF such as the Care-of-Address (CoA), Collocated CoA Mobile IPv6, and route...
With the increase of mobile and wireless communication in heterogeneous networks, the need for security has also increased. Mobile devices have to execute seamless and secure handover from one type of network to another. But before the actual execution, some security measures needs to be taken against denial of service and replay attacks. These measures require lengthy procedures for authentication...
