SYSTEM AND METHOD FOR SECURE PIER-TO-PIER COMMUNICATION BETWEEN DOWNLOADED PROGRAMS

摘要

PROBLEM TO BE SOLVED: To secretly communicate two copies of a program running on two different computers by sending a response message to accept the request of pier-to-pier communication connection when the requested computer satisfies a prescribed reference for that connection. SOLUTION: While a 1st computer program A1 is executed by a 1st computer C1, a message is sent to a 2nd computer C2 and the pier-topier communication connection is requested. When the 2nd computer C2 is matched with the prescribed reference for establishing the connection and a 2nd computer program C2 is executed there, the response message to accept the request is sent and received by the 1st computer C1 and the pier-to-pier communication connection is established. For a preferable example, this prescribed reference is the 1st and 2nd computer programs Al and A2 come from the same server computer S1.
