Abstract
Techniques for identifying a trusted SSID for a wireless network are disclosed. Prior to establishing a connection with a wireless network comprising a service set identifier (SSID), a network message is received at a wireless station (STA), from an access point (AP) associated with the wireless network. The STA identifies an encrypted identifier in the network message. The STA validates the encrypted identifier, and in response determines that the AP corresponds to a trusted wireless network. The SSID is designated as trusted, at the STA.
Claims20
A method of identifying a trusted SSID for a wireless network, comprising:
- prior to establishing a connection with a wireless network comprising a service set identifier (SSID), receiving a network message at a wireless station (STA) from an access point (AP) associated with the wireless network;
- identifying, at the STA, an encrypted identifier in the network message;
- validating, at the STA, the encrypted identifier, and in response determining that the AP corresponds to a trusted wireless network;
- and
- designating the SSID as trusted at the STA.
A wireless station (STA), comprising:
- a processor;
- and
- a memory storing a program, which, when executed on the processor, performs an operation, the operation comprising:
- prior to establishing a connection with a wireless network comprising a service set identifier (SSID), receiving a network message from an access point (AP) associated with the wireless network;
- identifying an encrypted identifier in the network message;
- validating the encrypted identifier, and in response determining that the AP corresponds to a trusted wireless network;
- and
- designating the SSID as trusted.
A wireless station (STA), comprising:
- a processor;
- and
- a memory storing a program, which, when executed on the processor, performs an operation, the operation comprising:
- prior to establishing a connection with a wireless network:
- receiving a first network message from a first access point (AP) identifying a first service set identifier (SSID) associated with a first wireless network;
- receiving a second network message from a second AP identifying a second SSID associated with a second wireless network;
- determining a visual similarity between a first visual representation of the first SSID and a second visual representation of the second SSID;
- and
- designating the second SSID as suspicious based on the determined visual similarity.
