What is 802.21a? Standard for Local and Metropolitan Area Networks: Media Independent Handover Services - Amendment for Security Extensions to Media Independent Handover Services and Protocol PAR (Project Authorization Request) https://development.standards.ieee.org/P647400033/par A copy of the PAR is also available as https://mentor.ieee.org/802.21/file/09/21-09-0010-00-0sec-p802-21a-par.pdf Schedule (c.f. Sections 4.2 and 4.3 of PAR) Expected Date of submission of draft to the IEEE-SA for Initial Sponsor Ballot: 11/2010 Projected Completion Date for Submittal to RevCom: 08/2011” 21-09-0012-00-0sec

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 802.21 (ii) to provide data integrity, replay protection, confidentiality and data origin authentication to IEEE 802.21 MIH (Media-Independent Handover) protocol exchanges and enable authorization for MIH services.” 21-09-0012-00-0sec

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.” 21-09-0012-00-0sec
