Secure transfer of medical images using hybrid encryption: Authentication, confidentiality, integrity

Abstract

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 a new encryption system for secure medical images transmission. The hybrid encryption system is based on AES and RSA algorithms. AES is used for data confidentiality, the RSA is used for authentication and the integrity is assured by the basic function of correlation between adjacent pixels in the image. Our encryption system generates a unique password every new session of encryption. Several parameters were used for various tests of our analysis.
