Cryptography provides a powerful means of verifying the authenticity of data and identifying the culprit. It plays vital role in many electronic applications. Information confidentially, authentication and integrity are desirable features for electronic transactions and these features are achieved by using a proper combination of symmetric and asymmetric cryptographic techniques. In order to ensure information authenticity, digital signatures are the equivalent part for normal signatures. Forgery of digital information can be identified with the help of digital signature. This paper intends to design secure electronic certificate and to control fake certificate for electronic learning system
