A Novel Optimal Key Selection Approach for Medical Image Encryption

The medical industry has been facing challenges in protecting the medical records of patients. To sustain privacy, it is important to secure medical images during their transmission. Therefore, a security mechanism must be implemented while transmitting medical images over the network. In order to handle security concerns, health organizations must implement efficient security strategies such as encryption techniques that would employ a better key generation and selection practice. In this study, chaotic maps are employed for the generation of keys. A novel approach is proposed to perform the optimal key selection process, which is vital in influencing the performance of an encryption algorithm. Thereby, in this paper, a novel Chaotic Bio-inspired Boosted Remora Optimization Algorithm is proposed for achieving a secure image transmission system based on an optimal key selection approach.
