4. What is 802.21a? (cont’d) Scope (c.f. Section 5.2 of PAR)
“This standard defines mechanisms
(i) to reduce the latency during authentication and key establishment for handovers between heterogeneous access networks that support IEEE
(ii) to provide data integrity, replay protection, confidentiality and data origin authentication to IEEE MIH (Media-Independent Handover) protocol exchanges and enable authorization for MIH services.”
sec

5. What is 802.21a (cont’d) Purpose (c.f. Section 5.4 of PAR)
“The purpose of this standard is to improve the user experience of mobile devices by minimizing the delay during handover between heterogeneous access networks through optimization of network access authentication and key establishment. Security-related message exchanges during handover can increase the latency significantly and in many cases service continuity cannot be met without such optimization.
Additionally, this standard will secure MIH protocol exchanges and enable authorization of MIH services. Without such security in place, MIH protocol entities and MIH services are vulnerable to various security attacks.”
