A new encryption algorithm is proposed and designed which is followed by a verification algorithm used to access such Internet-of-Things (IoT) based systems. A three Layer Encryption Algorithm (3LEA) is designed to generate a cryptographic Quick Response (QR) tag. In order to use this QR-tag as a secret key with IoT-based systems, a three Processes Verification Algorithm (3PVA) has been proposed to verify QR-tag values. In order to make a decision either to approve or disapprove a request to access an IoT-based system, a three-Layer Protection Algorithm (3LPA) is proposed. 3LPVA applies math operations to authenticate confidentiality, integrity, and availability of QR-tag (i.e., smart key). Thus, once the smart key is verified, an access to the IoT-based system is allowed. The 3LEA, 3PVA, and 3LPA are designed in such a way and capsulated using a new Encryption Scheme Method (ESM). The ESM contributes much to IoT technology era in terms of systems security; it is used as a smart key designer and verifier for IoT access systems. The ESM is evaluated in terms of security factors, decryption time, robustness, unpredictability, and 3LEA�s technical evaluation. Results show good performance of robustness and an unpredictability behavior of 3LEA. � Springer Nature Switzerland AG 2019.
