		For authentication of a given user at the intermediate party, the user is normally requested to send a user ID to the intermediate party, which in turn forwards this ID to the home operator authentication center in a request for authentication data.
		Preferably, the authentication data is interrelated, at the authentication center, to an identification of the intermediate party, and the authentication data is subsequently compared, at the authentication center, to received proof information (or a representation thereof) for verifying that the proof information is associated with the intermediate party.
		Example-a broker acting as an authentication center As previously indicated, the authentication center is not necessarily the authentication center of a particular home operator, but may be a broker 750 acting as a general authentication center, or identity center, for a number of different network operators, as schematically illustrated in Fig.

	United States Patent Application: 0010044296
		A method comprising: transmitting a request to update at least one parameter in a wireless terminal; receiving an authentication challenge from said wireless terminal in response to said request; and forwarding said authentication challenge to an authentication center that is associated with said wireless terminal.
		A wireless switching center is responsible for, among other things, establishing and maintaining a call between a first wireless terminal and a second wireless terminal or, alternatively, between a wireless terminal and a wireline terminal that is accessible via the local and/or long-distance networks.
		Because the authentication center uses the same values for s and x as does the wireless terminal, the result of the function is the same.

	Encyclopedia: Authentication Center
		The Authentication Centre or AUC is a function to authenticate each SIM card that attempts to connect to the GSM core network (typically when the phone is powered on).
		If the authentication fails, then no services are possible from that particular combination of SIM card and mobile phone operator attempted.
		After sucessful authentication, the MSC sends the encryption key Kc to the BSC so that all communications can be encrypted and decrypted.

	David Crowe - Wireless Review - Authentication - June 2000
		One approach to authentication would be to ask the mobile to provide a secret piece of information, just as banks may ask a customer for their mother’s maiden name to indirectly verify their identity.
		Authentication is now one of the most important aspects of modern public wireless networks.
		Carriers with authentication know that when a mobile phone requests service, it is authentically who it claims to be, as well as knowing that who it claims to be is valid for service.

	CERT® Coordination Center Reports
		Authentication is proving that a user is whom he or she claims to be.
		Coordination Center began operating in 1988, the number of security incidents reported to the center has grown dramatically, from less than 100 in 1988 to almost 2,500 in 1995, the last year for which complete statistics are available as of this writing.
		In the future, authentication protocols will increasingly be supported by technology that authenticates individuals (in the context of their organizational or personal roles) through the use of smart cards, fingerprint readers, voice recognition, retina scans, and so forth.

		Digital authentication systems are expected to become an essential part of doing business via the Internet.
		However, CDT asked the agency to expand on cases when authentication may not be necessary at all, to better ensure anonymity.
		CDT is reviewing the proposal to determine whether it is consistent with the authentication privacy principles released in May of this year by a working group convened by CDT.

		However, with diligence and adherence to strict security protocols, the Authentication Center could conceivably be made reasonably secure from theft of IMSI and Ki sets, both by outside and inside thieves.
		Instead of requiring the home system to test the results of authentication's "challenge and response" while the subscriber is roaming, the HLR may abdicate its authentication responsibilities to the VLR.
		The hard choices in deploying GSM authentication today are but one example of the weak spots that fraudsters target in their attack on GSM networks.

	Secure data center access: Authentication and encryption (Site not responding. Last check: 2007-10-07)
		Security is, without doubt, the paramount concern when considering the provision of data center access across non-private networks -- in particular the Internet.
		With at least 60% of vital corporate data resident on mainframes and AS/400s, data centers are the bastions of commercially sensitive assets critical for the sustenance of global enterprise.
		Unauthorized access to data center resources can thus result in serious financial misappropriations, loss of valuable customer records, the compromise of confidential corporate data and a general forfeiture of a competitive advantage.

	CloneSafe Authentication Product Line
		Authentication is a set of functions used to prevent fraudulent access to cellular and PCS networks by phones illegally programmed with stolen mobile identification number (MIN) and electronic serial number (ESN) information.
		Authentication functions require no subscriber intervention and provide a much more robust method of validating the true identity of a subscriber than do the basic service qualification procedures that have been used in the past.
		A successful outcome of authentication occurs when it can be demonstrated that the MS and network possess identical results of an independent calculation performed in both the MS and the network.

		If the two match, the user has been successfully authenticated, and the session keys, IK and CK, can be used for protecting further communications between the client and the server.
		The AUTS parameter is delivered to the network in the authentication response, and the authentication can be tried again based on authentication vectors generated with the synchronized sequence number.
		If the client successfully authenticates the server with the AUTN, and determines that the SQN used in generating the challenge is within expected range, the AKA algorithms are run with the RAND challenge and shared secret K. The resulting AKA RES parameter is treated as a "password" when calculating the response directive of RFC 2617.

	Dynamic Passcode Authentication \| Fact Sheets \| Media Center \| Visa Corporate (Site not responding. Last check: 2007-10-07)
		Dynamic passcode authentication allows cardholders to participate in a rigorous authentication process by using a smart card and a dynamic passcode generator that creates a one-time passcode for each online transaction made by a cardholder.
		The cardholder inserts a smart card into the passcode generator, enters their PIN as a way of validating their identity and the device displays a unique numeric passcode to prove the presence of the payment card.
		Also known as âtoken authentication,â dynamic passcodes are currently used in countries that have embraced chip technology, such as The Netherlands, Sweden, Norway and Belgium, where Internet banking is popular and security concerns are high.
