Medical Image Authentication Using Quartic Digital Signature Algorithm
S. Kishore Babu · International Journal of Intelligent Information Systems · 2018
The transmission of medical data in remote places using telemedicine technology requires secured and authenticated data transmission. In this paper, a novel technique is proposed to address authenticated mode of transmission using digital signature which incorporates curve coordinate system. The authentication functions and hash codes are used in the proposed algorithm and the keys are generated for secure transmission. The use of Quartic Digital Signature Algorithm (QDSA) provides authenticity and integrity. The Signature generated encapsulated in the DICOM header and transmitted to the receiver for verification. The proposed technique is demonstrated and evaluated using different modalities of DICOM images.
