The 2012 version of the standard includes features for Secure Authentication Version 5. The previous version of secure authentication in IEEE 1815-2010 used pre-shared keys only. The new version is capable of using Public Key Infrastructure , and it facilitates remote key changes.
A public key infrastructure (PKI) is a system for the creation, storage, and distribution of digital certificates which are used to verify that a particular public key belongs to a certain entity. The PKI creates digital certificates which map public keys to entities, securely stores these certificates in a central repository and revokes them ...
In practice, a supplicant is a software application installed on an end-user's computer. The user invokes the supplicant and submits credentials to connect the computer to a secure network. If the authentication succeeds, the authenticator typically allows the computer to connect to the network. IEEE 802.1x network-diagram example.
The Certificate Management Protocol (CMP) is an Internet protocol standardized by the IETF used for obtaining X.509 digital certificates in a public key infrastructure (PKI). CMP is a very feature-rich and flexible protocol, supporting many types of cryptography.
A noncompliant NAP client on the restricted network can access remediation servers and install the necessary components and updates. After remediation is complete, the NAP client can perform a new health evaluation in conjunction with a new request for network access or communication.
The authenticator is a network device that provides a data link between the client and the network and can allow or block network traffic between the two, such as an Ethernet switch or wireless access point; and the authentication server is typically a trusted server that can receive and respond to requests for network access, and can tell the ...
In fact, the term X.509 certificate usually refers to the IETF's PKIX certificate and CRL profile of the X.509 v3 certificate standard, as specified in RFC 5280, commonly called PKIX for Public Key Infrastructure (X.509). [4] An early issue with Public Key Infrastructure (PKI) and X.509 certificates was the well known "which directory" problem ...
The DC attributes are used to specify domain components of a DNS name, for example the domain name example.com could be represented by using the dc=com, dc=example format. If the CA's subject field would make use of such a format, the Issuer field would allow client applications to perform DNS lookups for the provided domain where the ...
