An example method of key management for encryption of traffic in a network having a network nodes includes negotiating, between a first network node and a centralized key management server, to obtain a master key shared among the network nodes; receiving, at the first network node, a first identifier for the first network node and a second identifier for a second network node; generating, at the first network node, a first session key by supplying the master key, the first identifier, and the second identifier as parametric input to a function; establishing, using a network stack of the first network node, a first point-to-point tunnel through the network to the second network node without a key exchange protocol; and sending first traffic from the first network node to the second network node through the first point-to-point tunnel, the first traffic including a portion encrypted by the first session key.
