Abstract
A mechanism to enable secure identification of roaming rights prior to authentication/association is provided. The mechanism may include using a Roaming ID, and may also include the use of wild cards and group IDs to reduce the length of transmissions. The mechanism may further employ public key infrastructure and puzzles to further enhance security and reduce the risk of denial of service attacks.
Claims37
A mobile station, comprising:
- a transmission portion configured to transmit a roaming ID to an access point;
- and
- a receiving portion configured to receive a list of service set identifiers (SSIDs) from the access point.
A mobile station, comprising:
- transmitting means for transmitting a roaming ID to an access point;
- and
- receiving means for receiving a list of service set identifiers (SSIDs) from the access point.
A method for obtaining a list of service set identifiers (SSIDs), the method comprising:
- transmitting a roaming ID to an access point;
- and
- receiving a list of SSIDs from the access point.
An access point, comprising:
- a reception portion configured to receive a roaming ID from a mobile station;
- and
- a processor portion configured to determine a list of service set identifiers (SSIDs) corresponding to the roaming ID,
- a transmission portion configured conditionally to transmit the list of SSIDs to the mobile station.
An access point, comprising:
- receiving means for receiving a roaming ID from a mobile station;
- determining means for determining a list of service set identifiers (SSIDs) corresponding to the roaming ID;
- and
- transmitting means for conditionally transmitting the list of SSIDs to the mobile station.
A method for providing a list of service set identifiers (SSIDs), the method comprising:
- receiving a roaming ID from a mobile station;
- determining a list of SSIDs corresponding to the roaming ID;
- and
- conditionally transmitting the list of SSIDs to the mobile station.
