Problem Statement

The objective of this project is to create a scalable model of an

online electronic payment system, allowing authorized users to

access and utilize their wealth from anywhere in the Internet using

the PRotocol Enhancement of DIgital Cash Transaction- II protocol.

Problem Statement .Contd..

Inputs.• User Information – name, Pass Phrase

etc.

• Amount of Cash to be transacted.

• The IP of the Zone Server.

• The IP and optionally the port of the Server socket of the remote client software.

• The Key Generation information (including no: bits RSA Key, Hashing algorithm for the password storage and other configuration information).

Outputs.

• Transaction Result–Whether

completed or aborted etc.

• Passbook format Transaction

information.

• Complete transaction

information.

• Personal information of

authorized client.

The Networking Aspects are handled by this package

The Aspects of the Database Connection, query etc.. are handled

Miscellaneous functions needed by all the packages are held in this package

Messages as required by the PREDICT II are defined in this package.

Test Plan

Main operation (function) in every class - allows for separate testing of each class. Functional tests –shows I/P and O/P of

each method for given set of values. Stress tests & boundary tests. Integration tests.
