INCREASED COMMUNICATION SECURITY

A method of increasing communication security may include determining, responsive to receiving a first message from a first computer system, whether said first computer system is authorized to communicate with a second computer system, wherein said determining is performed at a third computer system. The method may also include generating a first data portion associated with a security token, wherein said generating said first data portion includes accessing data, wherein said data includes a first instance of a session key, and wherein said generating said first data portion further includes encrypting, using a key associated with said second computer system, said data to generate said first data portion. The method may further include communicating, if said first computer system is authorized to communicate with said second computer system, a second message from said third computer system for delivery to said first computer system.
