Integrating ‘Network Pump’ with ATM Network Security.
College of Engineering Guindy, Anna University, Chennai, India - 1/1999-6/1999

As part of my senior year project, we developed a 'Network Pump' and 'Security
Agent' for ATM (Asynchronous Transfer Mode) Network Security. I was part of a team
of 3 members. The 'Network Pump' was developed to prevent the establishment of timing covert channels in a ATM Network. The timing covert channels are established by manipulating the ACK time.

Two Design methods were proposed, one using a randomization scheme and other
using probabilistic time interval based upon the Moving Average of the Previous ACKs.
The first method was implemented. This pump is built as a small layer in the ATM layer
of the ATM switch. . The Performance of the 'Network Pump' was found satisfactory.
The Security Agent (SA) provided two-way user authentication and access control. The SA used Three-way Security Message Exchange Protocol, to provide two-way
authentication of the user. It used RSA and data Encryption Standard (DES) for
encryption. And the access control services was provided, which used Fast data
Encipherment Algorithm (FEAL) for encryption.
