Ilayaraja Digital image security plays an essential role in the shared communication model. Encryption and decryption process is commonly applied to securely transmit the images in various real-time applications. In addition, the generation of encryptiondecryption keys is also essential to achieve enhanced image security. This study presents a multiple share creation scheme with an optimal signcryption (MSS-OSC) technique for digital image security. The MSS-OSC technique primarily generates a set of various shares for every digital image that needs to be transmitted. In addition, the encryption of generated shares takes place via the optimal signcryption (OSC) technique. Moreover, genetic programming (GP) is employed to optimally choose the keys involved in the encryption and decryption process. The detailed experimental validation of the MSS-OSC technique is investigated using a set of benchmark test images. The results analysis demonstrated that the MSS-OSC technique had a superior performance by accomplishing maximum digital image security. 2019 2019 26 36 10.54216/JISIoT.000103 https://www.americaspg.com/articleinfo/18/show/842
