This document specifies provision of connectionless user data confidentiality, frame data integrity, and data origin authenticity by media access independent protocols and entities that operate transparently to MAC Clients.<\/p>\n
NOTE\u2014The MAC Clients are as specified in IEEE Std 802\u00ae, IEEE Std 802.1Q?, and IEEE Std 802.1X.2<\/p>\n
To this end, it<\/p>\n
a) Specifies the requirements to be satisfied by equipment claiming conformance to this standard.<\/p>\n
b) Specifies the requirements for MACsec in terms of provision of the MAC Service and the<\/p>\n
preservation of the semantics and parameters of service requests and indications.<\/p>\n
c) Describes the threats, both intentional and accidental, to correct provision of the service.<\/p>\n
d) Specifies security services that prevent, or restrict, the effect of attacks that exploit these threats.<\/p>\n
e) Examines the potential impact of both the threats and the use of MACsec on the Quality of Service<\/p>\n
(QoS), specifying constraints on the design and operation of MAC Security entities and protocols.<\/p>\n
f) Models support of the secure MAC Service in terms of the operation of media access control method<\/p>\n
independent MAC Security Entities (SecYs) within the MAC Sublayer.<\/p>\n
g) Specifies the format of the MACsec Protocol Data Unit (MPDUs) used to provide secure service.<\/p>\n
h) Identifies the functions to be performed by each SecY, and provides an architectural model of its<\/p>\n
internal operation in terms of Processes and Entities that provide those functions.<\/p>\n
i) Specifies each SecY's use of an associated and collocated Port Access Entity (PAE,<\/p>\n
IEEE Std 802.1X) to discover and authenticate MACsec protocol peers and its use of that PAE's<\/p>\n
Key Agreement Entity (KaY) to agree and update cryptographic keys.<\/p>\n
j) Specifies performance requirements and recommends default values and applicable ranges for the<\/p>\n
operational parameters of a SecY.<\/p>\n
k) Specifies how SecYs are incorporated within the architecture of end stations, bridges, and two-port<\/p>\n
Ethernet Data Encryption devices (EDEs).<\/p>\n
l) Establishes the requirements for management of MAC Security, identifying the managed objects<\/p>\n
and defining the management operations for SecYs.<\/p>\n
m) Specifies the Management Information Base (MIB) module for managing the operation of MAC<\/p>\n
Security in TCP\/IP networks.<\/p>\n
n) Specifies requirements, criteria, and choices of Cipher Suites for use with this standard.<\/p>\n","protected":false},"excerpt":{"rendered":"
