  1. Management Frame Protection Study Group Request Emily Qi and Jesse Walker Intel Corporation Emily Qi & Jesse Walker, Intel Corporation

  2. Motivation • IEEE 802.11i does not define management frame protection scheme • IEEE 802.11 Management Frames are widely used in IEEE 802.11, its amendments, and Task Groups • Association, Disassociation, Reassociation, Deauthentication • 802.11r may or may not address security for these messages • Action frames (802.11h, 802.11k, 802.11e, potentially WNM) • Not being addressed by any existing projects or amendments Emily Qi & Jesse Walker, Intel Corporation

  3. Motivation (cont.) • WNM SG voted that it wants a single unified solution to the security problem • Concerned that different Task Groups propose different solutions  potential for security holes, implementation nightmares • Concerned non-security Task Groups lack sufficient security expertise • 802.11k participants concur • Single and unified solution needed for all IEEE 802.11 Management Frames Emily Qi & Jesse Walker, Intel Corporation

  4. Objective It is proposed that a Study Group be established to assess whether there is justification to form a task group to define a standard IEEE 802.11 management frame protection scheme Emily Qi & Jesse Walker, Intel Corporation

  5. Proposed SG Scope • Identify technical scope • Determine impacts on IEEE 802.11, for example: • Threat Analysis: Identify security threats to IEEE 802.11 management messages. • Potential Remediation: Determine whether available mechanisms are economically feasible and of utility to the community. • Decide whether a TG is needed, and if so define PAR and 5Criteria. Emily Qi & Jesse Walker, Intel Corporation

  6. Proposed SG Work • A decision regarding the creation of a Task Group • Creation of PAR and 5Criteria with the objective of producing an output document which defines how IEEE 802.11 management messages can be protected. • Draft set of input requirements • Determine relationships with other IEEE 802 groups. • To underpin specific requirements raised by external standardization bodies Emily Qi & Jesse Walker, Intel Corporation

  7. Motion • Move that the WNG SC recommends that the IEEE 802.11 WG form a study group to examine how to formally describe the IEEE 802.11 Management Frame and Control Frame protection functions and behaviors, with the intent to create a PAR and five criteria to form a new Task Group.
