Key threat prediction

An apparatus comprising:

• a network interface configured to provide or obtain one or more computer network communications protected by a key;
• and
• one or more processors coupled to the network interface, wherein the one or more processors are configured to:
• determine a count of the one or more computer network communications according to one or more properties of the one or more computer network communications;
• based on the count of the one or more computer network communications, compute an information entropy of the key;
• and
• based on the information entropy of the key, dynamically generate a predicted threat level of the key.

One or more non-transitory computer readable storage media encoded with instructions that, when executed by a processor of a network-connected device, cause the processor to:

• provide or obtain one or more computer network communications protected by a key;
• determine a count of the one or more computer network communications according to one or more properties of the one or more computer network communications;
• based on the count of the one or more computer network communications, compute an information entropy of the key;
• and
• based on the information entropy of the key, dynamically generate a predicted threat level of the key.
