Abstract: Since medical images include sensitive patient information, security is the top priority during transmission. In addition to protecting patient data from potential criminals, security helps to confirm the field staff’s identity. However, many medical institutions still need to adopt advanced security measures. In this paper, a new dual encryption method is proposed that implements blowfish and signcryption in a certificateless generalized form. The proposed method has an advantage over other methods due to its computational cost-effectiveness and speed. The performance measurements used to assess a proposed strategy’s effectiveness are PSNR, entropy, MSE, correlation coefficient (CC), and time taken. We obtain a high PSNR value of 57.72 and a low time requirement of 42 seconds on average. Combining blowfish and certificateless signcryption iTqnto one double encryption scheme that is computationally secure, fast, and easy to implement. It would help push hospitals toward a cost-effective image security environment.
