A New Approach for Text Encryption Using ECC

In modern world all data transmissions are performed electronically. Cryptography has an important role in the security of data transmission and is required to fulfill the set of basic objectives, like authentication, data integrity, non-repudiation and confidentiality. Cryptography protects our data from attempt of theft or an unauthorized use of data. In this work we proposed a method for which the text data is encrypted and decrypted using "Elliptic Curve Cryptographic algorithm" that can provides data integrity and confidentiality and Digital signature will be added to provide authentication and non-repudiation. This method developed in ad-hoc fashion and it supports text data only. Thus in our proposed method, the data transfer through network is very secure and also reduces the user's effort for transferring large data. The size of the key required for encryption and digital signatures is surely far less and its performance is good compared to other public cryptographic algorithms.
