EAP Attributes

  • Article

An EAP attribute is an EAP_ATTRIBUTE structure that contains a predetermined type of data relating to an authentication session. Attributes are used to communicate information between EAP methods and supplicants or between EAP methods and authenticators. Peer and authenticator implementations of an EAP method may exchange these attributes over a network.
