Provision of online transactions require the effectively and safely service, so the users can make sure that the entry data is secure and will not be used by other parties which are not authorized. Security is also necessary for the service provider side of online transactions, it is necessary to keep the system, and the data transactions sent through the communications media and the data stored in the database are secured. If the security guarantee is unavailable, the users will gradually lose their confidence to use the service through online transactions by using eGovernment application, and on the other hand the service provider will face the impact of the lost or corrupt data, and unauthorized access to the data which should be only accessed by involved parties based on the appropriate authority.
