Information technology - Telecommunications and information exchange between systems - Local and metropolitan area networks — Part 1AE: Media access control (MAC) security - First Edition
 N ISO/IEC/IEEE 8802-1AE

Annotation

The scope of this standard is to specify 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.

NOTE-The MAC Clients are as specified in IEEE Std 802, IEEE Std 802.2™, IEEE Std 802.1D™, IEEE Std 802.1Q™, and IEEE Std 802.1X™.2

To this end it

a) Specifies the requirements to be satisfied by equipment claiming conformance to this standard.

b) Specifies the requirements for MAC Security in terms of provision of the MAC Service and the preservation of the semantics and parameters of service requests and indications.

c) 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.
