Abstract

A hotspot provides an open wireless network and a secure wireless network. The open wireless network has no network-level encryption and allows open association therewith. The secure wireless network employs network-level encryption and requires authentication of a received access credential from a client device before allowing association therewith. A system for authorizing the client device for secured access at the hotspot includes an access controller configured to establish an encrypted connection between the client device and a login portal of the hotspot over the open wireless network, and to store a user-specific access credential transmitted via the encrypted connection as a valid access credential in a credential database. The credential database is accessed by wireless access points of the hotspot to authenticate the received access credential from the client device in response to a request from the client device to associate with the secure wireless network.

Claims

1. A method of enabling secured wireless access at a hotspot, the method comprising:

providing an open wireless network having no network-level encryption and allowing open association therewith by a client device;

providing a secure wireless network employing network-level encryption and requiring successful completion of an authentication process before allowing association therewith by the client device;

establishing an encrypted connection between the client device and a login portal of the hotspot over the open wireless network;

requiring a user of the client device to perform a predetermined sign-up process at the login portal via the encrypted connection;

adding a user-specific access credential as a valid access credential in a credential database, wherein the credential database stores a plurality of valid access credentials acceptable for gaining secure wireless access at the hotspot;

transmitting instructions from the login portal to the client device via the encrypted connection, the instructions instructing the user of the client device to switch the client device to a service set identifier (SSID) of the secure wireless network and to authenticate with the secure wireless network utilizing the user-specific access credential, wherein the instructions are displayed to the user by the client device and include both the service set identifier (SSID) of the secure wireless network and the user-specific access credential that is acceptable for associating with that service set identifier (SSID); and

providing secured wireless access to the client device over the secure wireless network after the user has associated the client device with the secure wireless network by following the instructions.

2. The method of claim 1, wherein at least a part of the user-specific access credential is a password.

3. The method of claim 1, wherein at least a part of the user-specific access credential is a username.

4. The method of claim 1, wherein at least a part of the user-specific access credential is transmitted from the client device to the login portal via the encrypted connection during the predetermined sign-up process.

5. The method of claim 1, wherein the user-specific access credential comprises a username and a password chosen by the user of the client device.

6. The method of claim 1, further comprising allowing the client device to access an external network over the secure wireless network after the client device has successfully associated with the secure wireless network until an access expiry time is reached.

7. The method of claim 1, further comprising causing a web browser running on the client device to establish a hypertext transfer protocol secure (HTTPS) connection with the login portal over the open wireless network after the client device has associated with the open wireless network.

8. The method of claim 1, further comprising:

receiving a request from the client device to associate with the secure wireless network after the user-specific access credential has been added to the credential database;

receiving the user-specific access credential from the client device as a part of the authentication process performed before the client device is allowed to associate with the secure wireless network;

accessing the credential database to check whether the user-specific access credential received from the client device during the authentication process corresponds to one of the valid access credentials stored in the credential database; and

allowing the client device to associate with the secure wireless network only when the user-specific access credential received from the client device during the authentication process corresponds to one of the valid access credentials stored in the credential database.

9. The method of claim 1, further comprising:

preventing the client device from accessing a particular network resource over the open wireless network; and

allowing the client device to access the particular network resource over the secure wireless network after the user has associated the client device with the secure wireless network by following the instructions.

10. The method of claim 1, further comprising disconnecting the client device from the secure wireless network in response to a predetermined time period expiring.

11. A non-transitory computer-readable medium comprising processor executable instructions that, when executed by one or more processors, cause the one or more processors to perform steps of:

providing an open wireless network having no network-level encryption and allowing open association therewith by a client device at a hotspot;

providing a secure wireless network employing network-level encryption and requiring successful completion of an authentication process before allowing association therewith by the client device;

establishing an encrypted connection between the client device and a login portal of the hotspot over the open wireless network;

requiring a user of the client device to perform a predetermined sign-up process at the login portal via the encrypted connection;

adding a user-specific access credential as a valid access credential in a credential database, wherein the credential database stores a plurality of valid access credentials acceptable for gaining secure wireless access at the hotspot;

transmitting instructions from the login portal to the client device via the encrypted connection, the instructions instructing the user of the client device to switch the client device to a service set identifier (SSID) of the secure wireless network and to authenticate with the secure wireless network utilizing the user-specific access credential, wherein the instructions are displayed to the user by the client device and include both the service set identifier (SSID) of the secure wireless network and the user-specific access credential that is acceptable for associating with that service set identifier (SSID); and

providing secured wireless access to the client device over the secure wireless network after the user has associated the client device with the secure wireless network by following the instructions.

12. A system enabling secured wireless access at a hotspot, the system comprising:

one or more access points providing an open wireless network having no network-level encryption and allowing open association therewith by a client device;

one or more access points providing a secure wireless network employing network-level encryption and requiring successful completion of an authentication process before allowing association therewith by the client device;
