A permitting system for controlling devices in a system includes a permit issuing agent that receives a command to be sent to a device. Based upon at least one attribute of the command, the permit issuing agent identifies one or more business logic modules that is pertinent to the command. Each business logic module has a respectively different set of business rules associated with it. Each identified business logic module determines whether the command complies with the business rules associated with that module. If the command is determined to comply with the business rules of all of the identified business logic modules, the agent issues a permit for the command, and the permit is sent to the device for execution of the command.

A method for removing credentials from a smart grid device includes: receiving, by a receiving device, a removal request, wherein the removal request includes a device identifier associated with a smart grid device and is signed by an entity associated with a set of security credentials stored in a memory of the smart grid device, the set of security credentials restricting access to one or more components or operations of the smart grid device; extracting, by a processing device, the device identifier included in the received removal request; generating, by the processing device, a permit configured to remove the set of credentials from the smart grid device, wherein the generated permit includes the extracted device identifier; and transmitting, by a transmitting device, the generated permit to the smart grid device for removal of the set of credentials from the memory of the smart grid device.

Methods and systems a provided for security in a wireless utility network. The methods and systems use different levels of trust to securely enroll new nodes into a network through other nodes acting as proxies. A node's security state with respect to another node in the network is categorized into one of several trust levels. A node responds to certain requests, actions or messages depending based on its trust level with the other entity. Initially, a node is not trusted. A first trust level is established based on a digital certificate that is stored in a node when the node is manufactured. A second trust level is established based on a second digital certificate obtained from a certifying authority while a node is in the first trust level. A node with a verified second certificate can be fully enrolled in the network and participate as a network node with minimal or no constraints.
