Abstract
A method includes, with a first computing system, sending a request over a network to a second computing system and receiving a response to the request over the network from the second computing system. The method further includes, with the first computing system, measuring a latency based on the request and the response, dividing the latency by a threshold value, resulting in a quotient, and determining whether to allow the second computing system to engage in secure communications with the first computing system.
