摘　　要：The advancements made in Internet of Things(IoT)is projected to alter the functioning of healthcare industry in addition to increased penetration of different applications.However,data security and private are challenging tasks to accomplish in IoT and necessary measures to be taken to ensure secure operation.With this background,the current paper proposes a novel lightweight cryptography method for enhance the security in IoT.The proposed encryption algorithm is a blend of Cross Correlation Coefficient(CCC)and Black Widow Optimization(BWO)algorithm.In the presented encryption technique,CCC operation is utilized to optimize the encryption process of cryptography method.The projected encryption algorithm works in line with encryption and decryption processes.Optimal key selection is performed with the help of Artificial Intelligence(AI)tool named BWO algorithm.With the combination of AI technique and CCC operation,optimal security operation is improved in IoT.Using different sets of images collected from databases,the projected technique was validated in MATLAB on the basis of few performance metrics such as encryption time,decryption time,Peak Signal to Noise Ratio(PSNR),CC,Error,encryption time and decryption time.The results were compared with existing methods such as Elliptical Curve cryptography(ECC)and Rivest-Shamir-Adleman(RSA)and the supremacy of the projected method is established.
