Enhancing Robustness of EC Cryptic Data using Forward Error Correction
Aanchal Aggarwal, Sunita Sangwan · 2012
With the explosion of networks and the huge amount of data transmitted along, the data content needs to be secured. Data encryption ensures security in open networks such as the Internet. With the fast development of cryptography research and computer technology, the cryptosystems such as of RSA and Diffie-Hellman require large number of bits so they became inadequate. The cryptosystem based on Elliptic Curve Cryptography is becoming the recent trend of public key cryptography. This paper presents the implementation of Elliptic Curve Cryptography by first transforming the message (text and image) into an affine point on the Elliptic Curve over the finite prime field. Here we illustrate the process of encryption of a text and image message and then a method for enhancing security using Forward Error Correction code for better error checking at the receiver side. This enables errors or noise added during transmission to be detected and corrected so that the receiver is receiving correct data and the received data matches with the sent data. Forward error correction is applied to progressive data to provide graceful degradation of text and image quality as packet losses increase.
