A scheme based on ECDSA and its implementation for information security

Cryptography methods are means of securing digital data on a network. Digital signature on a document today is trendy in the digital world for authentication, authorisation, integrity, and non-repudiation. The elliptical curve digital signature algorithm (ECDSA) has been implemented and proved that it requires a key size of small length as compared to the RSA. However, its implementation for image and audio security is lacking in the literature. Hence, this paper has proposed a scheme based on ECDSA for text, image, and audio security over networks. Further, the proposed method is implemented on text, image, and audio using both LabVIEW software and myRIO hardware and verified for authentication.
