Abstract

Dynamic wireless link security can be used to connect a wireless computing device to a wireless network. A determination is made as to the minimum level of security required and a wireless communication channel corresponding to that level of security is selected from among multiple, available wireless communication channels with varying levels of security. At least one of the wireless communication channels is an unencrypted channel with access control, which can be used when information is already encrypted or when encryption is not needed due to low sensitivity of the information. The determination can be made with user input or by inspecting metadata in content to be sent over the wireless link.

Claims14

Dependent claims

A system comprising:

a wireless local area network interface;
a processor communicatively coupled to the wireless local area network interface, wherein the processor is configured to perform operations comprising:
connecting to a wireless computing device using an encrypted channel from among a plurality of simultaneous wireless communication channels with varying levels of security;
determining a level of security required for a data communication link between the wireless local area network interface and the wireless computing device;
selecting a wireless communication channel corresponding to the level of security required from among the plurality of simultaneous wireless communication channels with varying levels of security, wherein the plurality of simultaneous wireless communication channels comprises an unencrypted channel with access control along with the encrypted channel;
providing a seed media access control (MAC) address to the wireless computing device over the encrypted channel;
providing a polynomial to the wireless computing device over the encrypted channel, the polynomial configured to enable rolling the seed MAC address to a current MAC address from a series of MAC addresses over time;
and
establishing the data communication link over the wireless communication channel using the current MAC address and the wireless local area network interface.
