摘要： The invention provides a method for improving the security of a mobile terminal in a WLAN environment by installing two shared secrets instead of one shared secret, the initial session key, on both the wireless user machine and the WLAN access point during the user authentication phase. One of the shared secrets is used as the initial session key and the other is used as a secure seed. Since the initial authentication is secure, these two keys are not known to a would be hacker. Although the initial session key may eventually be cracked by the would be hacker, the secure seed remains secure as it is not used in any insecure communication.
摘要翻译：本发明提供一种通过在用户认证阶段期间在无线用户机器和WLAN接入点上安装两个共享秘密而不是一个共享秘密（初始会话密钥）来提高WLAN环境中的移动终端的安全性的方法。共享秘密之一被用作初始会话密钥，另一个用作安全种子。由于初始身份验证是安全的，所以这两个密钥对于黑客来说是不知道的。虽然初始会话密钥可能最终被黑客破解，但安全种子仍然是安全的，因为它不会用于任何不安全的通信。

摘要： A public wireless LAN (11) permits receipt of non-authentication traffic, such as access information requests, from a mobile wireless communications device (121) prior to device authentication by partially opening a controlled port within an access point (181). The wireless LAN re-directs such non-authentication traffic received at the AP from the mobile wireless communications to a local web server (21). The local web server provides reply to the mobile wireless communications device, enabling a determination by the device whether or not to request access. The device seeks access by way of an access request received at the AP. In response, the AP re-directs the access request through an uncontrolled port in the AP to an access server (26) that authenticates device. Upon successful device authentication, the AP fully opens its controlled port to permit the exchange of traffic through that port with the mobile wireless communications device.

摘要： An operator of a network (20) dynamically establishes a business relationship with a Billing Agent (26) to enable the network operator to receive reimbursement for access charges incurred by one or more users (121, 122 and 123). To establish such a relationship, the network operator first opens a communications channel to the Billing Agent after which the network operator and Billing Agent verify each other. Following verification, the network operator communicates proposed business terms and conditions, including access charges, to the Billing Agent. In response, the Billing Agent sends to the network operator an acceptance of business terms acceptable to the Billing Agent. After reaching agreement on the terms and conditions, the Billing Agent and network operator will each digitally acknowledge a formal agreement that embodies the agreed upon terms.

摘要： The invention herein provides an apparatus and a method for automatically configuring an IEEE 802.1x client terminal (140); to provide limited access in a WLAN environment, specifically utilizing the access point to filter traffic associated with the limited access so as to redirect the client terminal's HTTP request to a designated local web server (150); The web server responds to the client terminal by requesting information required to establish an authorized communication. Thereafter the client terminal provides information required to establish an authorized communication. In the course of the communication the web server sends information such as transmission rates, new user account creation information, authentication method selection, and access user terms and conditions of acceptance, all typically required to establish an authorized access. The client responds with information, required to establish an authorized communication.

摘要： A user (12 1 , 12 2 ) can access a Local Area Network (LAN) (20) on a fee basis without risking transmission of an un-encrypted PIN at upon initial access. The user initially sends a request to the LAN identifying a Billing Agent (26) that maintains an account associated with the user for payment of LAN access charges. The account can be a pre-paid account identified only by a PIN known to the user. After the user has identified the Billing Agent, the LAN queries the Billing Agent for its digital certificate, which the LAN forwards to the user. The user utilizes the certificate to encrypt a PIN for transmission via the LAN to the Billing Agent for authentication. Upon successful authentication, the Billing Agent authorizes the LAN to grant access to the user, allowing the user to connect via the LAN to a private network (14) or a public network (16).
摘要翻译：用户（121,122）可以以费用方式访问局域网（LAN）（20），而不会在初次访问时传输未加密的PIN的风险。用户最初向LAN识别出一个账单代理（26）的请求，该计费代理（26）维护与该用户相关联的帐户以支付LAN访问费用。该帐户可以是仅由用户熟知的PIN识别的预付费帐户。在用户识别出计费代理之后，LAN会向计费代理查询其数字证书，LAN将转发给用户。用户利用证书加密PIN，以便经由LAN传送到计费代理进行认证。在成功认证后，计费代理授权LAN授予对用户的访问权，允许用户经由LAN连接到专用网络（14）或公共网络（16）。
