The AAA server typically interacts with network access and gateway servers and with databases and directories containing user information.
A network element used by Hotspot Operators to provide an entrance point to the Internet.
In iPass terms, a local network connection point. An access point can be any of several types: wired broadband, dial-up, or Wi-Fi.

An 802.11 Networking framework in which devices or stations communicate directly with each other, without the use of an access point (AP). Ad-hoc mode is also referred to as peer-to-peer mode or an Independent Basic Service Set (IBSS). Ad-hoc mode is useful for establishing a network where wireless infrastructure does not exist or where services are not required.

iPass releases new versions of Open Mobile and iPassConnect software at regular intervals. Each application will automatically receive program upgrades and can be designed to receive configuration file updates, freeing administrators from having to deploy new software versions.
The ability for Open Mobile (or iPassConnect) to automatically connect to a network without any user interaction.
In iOS, the ability to login automatically into a network without any user interaction.
After successful iPass authentication, and directory and configuration updates, Open Mobile and iPassConnect will give the user 60 seconds to successfully connect to the VPN. If the user does not successfully connect to the VPN within 60 seconds, the client application will disconnect the user from the Internet. Furthermore, if the user does connect to the VPN and then disconnects the VPN during the connection (without manually disconnecting), the client will terminate the Internet connection. In order to use this feature, the customer must also have an integrated auto-launched VPN.

CDRs detail each originating location, destination, date, time, access method, and length of connection. CDRs are generated at the end of the connection session.
A trusted third-party organization or company that issues digital certificates used to create digital signatures and public-private key pairs. The role of the CA in this process is to guarantee that the individual granted the unique certificate is, in fact, who he or she claims to be. Usually, this means that the CA has an arrangement with a financial institution, such as a credit card company, which provides it with information to confirm an individual's claimed identity.
A password-less AAA protocol which compares a hashed user’s password to verify each side holds the correct password. After the link is made, the server sends a challenge message to the connection requestor. The requestor responds with a value obtained by using a one-way hash function. The server checks the response by comparing it its own calculation of the expected hash value. If the values match, the authentication is acknowledged; otherwise the connection is usually terminated. At any time, the server can request the connected party to send a new challenge message. Because CHAP identifiers are changed frequently and because authentication can be requested by the server at any time, CHAP provides more security than PAP.
An application for connecting to a server or network. In iPass usage, specifically, Open Mobile or its predecessor, iPassConnect.
A feature of Open Mobile for Windows that enables the determination of whether the user is connected to a corporate network. A variety of tests may be configured to make this determination.

Extends EAP-TLS authentication negotiation by using the secure connection established by the TLS handshake to exchange additional information between client and server. It allows legacy password-based authentication protocols to be used against existing authentication databases, while protecting the security of these legacy protocols against eavesdropping, man-in-the-middle and other cryptographic attacks.

A connection not initiated by Open Mobile or iPassConnect, but managed by them.
The tunneled EAP methods such as EAP-TTLS and PEAP support a concept called identity hiding. Authentication between the supplicant and authentication server takes place in two phases. In the first phase, the supplicant presents an outer user identity, in response to which the authentication server establishes an encrypted tunnel. This outer identity is often an anonymous user. The supplicant then presents the true user name as the inner identity used by the authentication method transported through the tunnel. Because the encrypted tunnel has its endpoints at the supplicant and the authentication server, the users true identity is hidden from the access point. Only the outer identity is visible to the access point.

In the first phase, the supplicant presents an outer user identity, in response to which the authentication server establishes an encrypted tunnel. This outer identity is often an anonymous user. The supplicant then presents the true user name as the inner identity used by the authentication method transported through the tunnel. Because the encrypted tunnel has its endpoints at the supplicant and the authentication server, the users true identity is hidden from the access point. Only the outer identity is visible to the access point.
A simple authentication protocol that requires users to enter a password before accessing a secure system. The username and password are sent over the network to a server, where they are compared with a database of user account names and passwords.

WEP is available in 40-bit (also called 64-bit), or in 108-bit (also called 128-bit) encryption modes. As 108-bit encryption provides a longer algorithm that takes longer to decode, it can provide better security than basic 40-bit (64-bit) encryption.

802.11, or IEEE 802.11, is a type of radio technology used for wireless local area networks (WLANs). It is a standard that has been developed by the IEEE (Institute of Electrical and Electronic Engineers), Wi-Fi, 802.11, is composed of several standards operating in different radio frequencies.
An IEEE specification for wireless networking that operates in the 5 GHz frequency range (5.725 GHz to 5.850 GHz) with a maximum 54 Mbps data transfer rate. The 5 GHz frequency band is not as crowded as the 2.4 GHz frequency, because the 802.11a specification offers more radio channels than the 802.11b. These additional channels can help avoid radio and microwave interference. 802.11a uses an orthogonal frequency division multiplexing encoding scheme rather than FHSS or DSSS.
International standard for wireless networking that operates in the 2.4 GHz frequency range (2.4 GHz to 2.4835 GHz) and provides a throughput of up to 11 Mbps. This is a very commonly used frequency. Microwave ovens, cordless phones, medical and scientific equipment, as well as Bluetooth devices, all work within the 2.4 GHz frequency band. An extension to 802.11 that applies to wireless LANS and provides 11 Mbps transmission (with a fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz band. 802.11b was a 1999 ratification to the original 802.11 standard, allowing wireless functionality comparable to Ethernet. Also referred to as 802.11 High Rate or Wi-Fi.
802.11g Similar to 802.11b, but this standard provides a throughput of up to 54 Mbps. It also operates in the 2.4 GHz frequency band but uses a different radio technology in order to boost overall bandwidth.
The 802.1X standard provides the ability to identify who is attempting to gain access to a given port. There are five components to 802.1x deployment.
