1. A method comprising:

receiving, by a first node of a mesh network, a message;

determining, by the first node, a security key type based on a resource parameter associated with a neighbor node included in the mesh network;

securing, by the first node, the message using a security key of the security key type; and

transmitting, by the first node, the secured message to the neighbor node;

wherein the resource parameter associated with the neighbor node comprises at least one of an amount of memory used to decrypt the secured message at the neighbor node, an amount of power used to decrypt the secured message at the neighbor node, or an indication of an amount of power remaining at the neighbor node.
