Shaikh Ammarah P., Vikas Kaul, S K Narayankhedkar . Security Enhancement Algorithm for Data Transmission using Elliptic Curve Diffie - Hellman Key Exchange. International Conference and workshop on Advanced Computing 2014. ICWAC2014, 2 (June 2014), 0-0.
Data Security for end-end transmission is achieved by many different symmetric and asymmetric techniques for message confidentiality, message authentication and key exchange using transport layer security. This paper presents the combination of two symmetric algorithms AES and Blowfish to enhance security. AES is enhanced by modifying the S-boxes columns, and then combination of enhanced AES and blowfish is used for data confidentiality. Message digest 5 is used for authentication. Key exchange is done using ECDHA, Elliptic Curve Diffe Hellman algorithm. ECDSA is used for digital signature. Performance of this system is evaluated for text file, image file, audio file and video file on the basis of encryption/decryption processing time and throughput.
