Generating protocol-specific keys for a mixed communication network

A device, comprising:

• a memory configured to store a network key associated with a mixed communication network, the mixed communication network associated with a first network communication protocol and a second network communication protocol;
• a key generator configured to generate a first protocol-specific key for use with the first network communication protocol, the first protocol-specific key based at least in part upon the network key and a first identifier corresponding to the first network communication protocol;
• and
• a first communication interface configured to communicate via the first network communication protocol using the first protocol-specific key.

A non-transitory computer readable storage medium storing program instructions, wherein the program instructions executed by a processor of a first device cause the first device to:

• receive a network key associated with a mixed communication network, the mixed communication network associated with a first network communication protocol and a second network communication protocol;
• generate, at the first device, a first protocol-specific key for use with the first network communication protocol of the mixed communication network, the first protocol-specific key based at least in part on the network key and first identifier corresponding to the first network communication protocol;
• and
• communicate with a second device in the mixed communication network via the first network communication protocol using the first protocol-specific key.
