This standard specifies the air interface, including the cognitive medium access control layer (MAC) andphysical layer (PHY), of point-to-multipoint wireless regional area networks comprised of a professionalfixed base station with fixed and portable user terminals operating in the VHF/UHF TV broadcast bandsbetween 54 MHz to 862 MHzc) Describes the threats, both intentional and accidental, to correct provision of the service.d) Specifies security services that prevent, or restrict, the effect of attacks that exploit these threats.e) Examines the potential impact of both the threats and the use of MAC Security on the Quality of Service (QoS), specifying constraints on the design and operation of MAC Security entities and protocols.f) Models support of the secure MAC Service in terms of the operation of media access control method independent MAC Security Entities (SecYs) within the MAC Sublayer.g) Specifies the format of the MACsec Protocol Data Unit (MPDUs) used to provide secure service.h) Identifies the functions to be performed by each SecY, and provides an architectural model of its internal operation in terms of Processes and Entities that provide those functions.i) Specifies the interface/exchanges between a SecY and its associated and collocated MAC Security Key Agreement Entity (KaY, IEEE P802.1af [B2]) that provides and updates cryptographic keys.j) Specifies performance requirements and recommends default values and applicable ranges for the operational parameters of a SecY.k) Specifies how SecYs are incorporated within the architectural structure within end stations and bridges.l) Establishes the requirements for management of MAC Security, identifying the managed objects and defining the management operations for SecYs.m) Specifies the Management Information Base (MIB) module for managing the operation of MAC Security in TCP/IP networks.n) Specifies requirements, criteria and choices of Cipher Suites for use with this standard.This standard does noto) Specify how the relationships between MACsec protocol peers are discovered and authenticated, assupported by key management or key distribution protocols, but makes use of IEEE P802.1af KeyAgreement for MAC security to achieve these functions.
