  Nowadays different state and central government in India as well as abroad
are taking initiative to deliver different kind of services electronically
specially using Information and Communication Technology (ICT). Intruders or
hackers can steal or modify the information communicated between Government and
consumer through internet. To implement privacy and confidentiality of the
information we must use suitable encryption technique. In this paper an Object
Oriented Modelling of International Data Encryption Algorithm (IDEA) using GA
based efficient key generation technique has been proposed to incorporate
privacy and confidentiality of information which would be communicated between
government and consumer.
