Abstract
Systems, methods, and devices for broadcast wireless local area network messages with message authentication are contained herein. The method includes determining a digital signature for a broadcast packet to be transmitted to a plurality of devices on a wireless local area network, the digital signature encrypted using asymmetric cryptography to enable each of the plurality of devices to verify an identity of a device transmitting the broadcast packet. The method further includes transmitting the broadcast packet on the network, the broadcast packet including the digital signature.
Claims30
A method of wireless communication comprising:
- determining a digital signature for a broadcast packet to be transmitted to a plurality of devices on a wireless local area network, the digital signature encrypted using asymmetric cryptography to enable each of the plurality of devices to verify an identity of a device transmitting the broadcast packet;
- and
- transmitting the broadcast packet on the network, the broadcast packet including the digital signature.
A wireless communication apparatus comprising:
- a transmitter configured to:
- determine a digital signature for a broadcast packet to be transmitted to a plurality of devices on a wireless local area network, the digital signature encrypted using asymmetric cryptography to enable each of the plurality of devices to verify an identity of a device transmitting the broadcast packet;
- and
- transmit the broadcast packet on the network, the broadcast packet including the digital signature.
A wireless communication apparatus comprising:
- means for determining a digital signature for a broadcast packet to be transmitted to a plurality of devices on a wireless local area network, the digital signature encrypted using asymmetric cryptography to enable each of the plurality of devices to verify an identity of a device transmitting the broadcast packet;
- and
- means for transmitting the broadcast packet on the network, the broadcast packet including the digital signature.
A non-transitory, computer readable medium comprising instructions that when executed cause a processor in a device to perform a method for wireless communication, the method comprising:
- determining a digital signature for a broadcast packet to be transmitted to a plurality of devices on a wireless local area network, the digital signature encrypted using asymmetric cryptography to enable each of the plurality of devices to verify an identity of a device transmitting the broadcast packet;
- and
- transmitting the broadcast packet on the network, the broadcast packet including the digital signature.
The computer readable medium of claim 25, wherein asymmetric cryptography comprises elliptic curve cryptography.
The computer readable medium of claim 30, wherein transmitting the public key comprises transmitting the public key and an expiry time for the public key.
