Abstract
A method of increasing communication security may include determining whether a first computer system is authorized to communicate with a second computer system, wherein the determining is performed at a third computer system. A message may be communicated from the third computer system for delivery to the first computer system, wherein the message includes a first data portion and a second data portion, wherein the first data portion includes a first instance of a session key, and wherein the second data portion includes a second instance of the session key. Another message, including the first data portion, may be communicated from the first computer system for delivery to the second computer system. Yet another message may be communication from the first computer system for delivery to the second computer system. Message validation associated with the yet another message may be performed using the first instance of the session key.
