The contribution of smart mobility devices to the Internet of Things (IoT) has transformed everyday life, offering the ability to access and manage vast quantities of data in a revolution that continues to sweep the world. However, this incredible progress has led to the development of new challenges. The most significant of which is the continuing requirement for up-to-date security measures. Conventional solutions have tended to require heavier hardware while remaining vulnerable to new attack strategies; therefore, they are inappropriate for end-to-end SDs within the IoT-cloud. To overcome this problem, we propose a secure and lightweight solution that offers the combined security benefits of resistance data against attack and maintenance of privacy in communications for end-to-end E2E SDs. The strategy proposed is based on the least significant bit, cryptographic hash function randomization, with quick response (QR) message application. The proposed scheme offers many advantages, including user anonymity and message privacy, data integrity, key agreement, and one-time message code for each user session. The scheme also has additional commercial benefits given that QR code reading and generation does not result in additional costs. The results demonstrate the potential wide-ranging benefits, applications, and performance improvements.
