EAP Types – Extensible Authentication Protocol Types
Because protected success indications are not used in this example, the EAP server sends the EAP-Success packet, indicating that the authentication was successful. This phase is independent of other phases; hence, any other scheme in-band or out-of-band can be used in the future. Used on eap-skm authentication only. Message Sequence Examples Informative Webarchive template wayback links Pages using RFC ep-sim links All articles with specifically marked weasel-worded phrases Articles with specifically marked weasel-worded phrases from January All articles with unsourced statements Articles with unsourced statements from April Wikipedia articles with GND identifiers.
The permanent identity is usually based on the IMSI.
Extensible Authentication Protocol
The EAP-SIM mechanism specifies enhancements to GSM authentication and key agreement whereby multiple authentication triplets can be combined to create authentication responses and session keys of greater strength than the individual GSM triplets. Authentication vector GSM triplets can be alternatively called authentication vectors. The protocol only specifies chaining multiple EAP mechanisms and not any specific method. Permanent Username The username portion of permanent identity, i.
Fast re-authentication is based on keys derived on full authentication. The alternative is to use device passwords instead, but then the device is validated on the network not the user.
From Wikipedia, the free encyclopedia. A pseudonym identity of the peer, including an NAI realm portion in environments where a realm is used. It can use an existing and widely deployed authentication protocol and infrastructure, incorporating legacy password mechanisms and authentication databases, while the secure tunnel provides protection from eavesdropping and man-in-the-middle attack.
There are currently about 40 different methods defined. PEAPv1 was defined in draft-josefsson-pppext-eap-tls-eap through draft-josefsson-pppext-eap-tls-eap and PEAPv2 was defined in versions beginning with draft-josefsson-pppext-eap-tls-eap The client can, but does not have to be authenticated via a CA -signed PKI certificate to the server.
Communicating the Peer Identity to the Server EAP-TLS is still considered one of the most secure EAP standards available, although TLS provides strong security only as long as the user understands potential warnings about false credentials, and is universally supported by all manufacturers of wireless LAN hardware and software.
Used on fast re-authentication only. Wireless networking Computer access control protocols. Fall Back to Full Authentication Distribution of this memo is unlimited.
This mechanism specifies enhancements to GSM authentication and key agreement whereby multiple authentication triplets can be combined to create authentication responses and session keys of greater strength than the individual GSM triplets. Microsoft Exchange Server Unleashed. WPA2 and potentially authenticate the wireless hotspot. For example, in IEEE The username portion of permanent identity, i.
The EAP-POTP 4168 provides two-factor user authentication, meaning that a user needs both physical access to a token and knowledge of a personal identification number PIN to perform authentication.
In general, a nonce can be predictable e.
Extensible Authentication Protocol – Wikipedia
Used on fast re-authentication only. Cryptographic Separation of Keys and Session Independence Key establishment to provide confidentiality and integrity during the authentication process in phase 2. Integrity and Replay Protection, and Confidentiality Additionally a number of vendor-specific methods and new proposals exist. Second generation mobile networks and third generation mobile rgc use different authentication and key agreement mechanisms.
After the server is securely authenticated to the client via its CA certificate and optionally the client to the server, the server can then use the established secure connection “tunnel” to authenticate the client. Format, Generation and Usage of Peer Identities Message Format and Protocol Extensibility Used on full authentication only.
Protected success indications are discussed in Section 6.
The mechanism also includes network authentication, user anonymity support, result indications, and a fast re-authentication procedure. Since some wap-sim properties may depend on the randomness of the nonce, attention should be paid to whether a nonce is required to be random or not. The lack of mutual authentication in GSM has also been overcome.
EAP-AKA and EAP-SIM Parameters
A fast re-authentication identity of 44186 peer, including an NAI realm portion in environments where a realm is used. EAP-SIM also extends the combined RAND challenges and other messages with a message authentication code in order to provide message integrity protection along with mutual authentication.
The permanent identity is usually based on the IMSI. Traditionally a smart card distributed by a GSM operator.
