In the last blog, I unilaterally declared (without any evidence
to back me up) that intercept of payer data posed the greatest vulnerability to
payment hubs generally. I decided to show the attacking environment generally
and show why I think so.
In two earlier blogs (see http://paymentnetworks.blogspot.com/2014/07/turnstiles.html
and http://paymentnetworks.blogspot.com/2014/07/payment-systems-of-underground-economies.html
), I showed how the construction of valves and turnstiles within payment clearing
nodes decreased throughput of clearing flow. I want to further define these elements
generally as gates and state a general relationship that where gates are
present points of intercept (POI) are also present. I define a point of
intercept as processing environment that single threads transaction data
thereby potentially forming queues. I define queues as collection of data
waiting for processing.
Given these definitions Diagram 24 shows the relationship as
time passes.
Diagram 25 shows that as processing delays increase data
queues increase exponentially exposing transaction data to intercept for
greater time. Emphasizing that I have no data to make this conjecture and that
the relationship will actually be something different, I still conjecture that
the relationship exists and looks similar to data displayed in Diagram 25.
Diagram 25: Relationship
between Gates and Transaction Data in Queues
So, expenditure for defense may come in the form of
decreasing gates.
