Self-Configuring Key Management System For an Internet of Things Network

A first device comprising:

• at least one hardware processor to execute instructions;
• at least one network interface to enable the at least one hardware processor to communicate with second and third computing nodes coupled in an Internet of Things (IoT);
• at least one non-transitory storage medium having instructions stored thereon for causing the at least one hardware processor of the first device to:
• receive at least one of a first symmetric key and a first asymmetric key in a common key management structure, the common key management structure to accommodate asymmetric keys and symmetric keys, wherein the common key management structure includes security policy information to enable communication between the first device of a first domain of an Internet of Things (IoT) network and a second device of a second domain of the IoT network according to an inter-domain security policy;
• and
• send a first message directly to the second device according to the security policy information of the common key management structure.
