Intruders are generating smart ways to listen the information un-authentically, whereas the information scientists have to find even smarter ways for neutralizing these attempts. Citizens being the digital identities should be able to access various electronic facilities by communicating with the E-Governance mechanism. Digital certificates are the online passport generated by the trusted certificate authorities for authentication of the Citizens. By the incorporation of the object oriented approach, the entire mechanism can be implemented more efficiently. In this paper the authors have described the application of digital certificates through the UML based approach to explain the secured smart card based data transmission in the C2G model of E-Governance.

Intruders are generating smart ways to listen the information un-authentically whereas the information scientists have to find even smarter ways for neutralizing these attempts. Citizens being the digital identities should be able to access various electronic facilities by communicating with the E-Governance [1, 2, 4, 6, 7, 8, 9] mechanism. The industry standard data encryption and decryption techniques, digital signature algorithms [10], digital certificates [11, 12], etc may be deployed for secured mobilization of information in the entire mechanism. Digital certificates are the online passport generated by the trusted certificate authorities for authentication [5] of the Citizens. Moreover, the benefits of object oriented approach [13] will act an value addition to the proposed smart card based C2G type of E-Governance model. Section – 2 contains the relevant literature review in precise form. The UML based proposed model is mentioned in the section – 3. The conclusion drawn is stated in section – 4.
