Abstract

The Internet of Things (IoT) has gained attention in industry and education. It involves collecting data from millions of sensor-equipped devices and using that data to create smart systems like the smart grid, smart city, and smart healthcare. It is important to set up a safe channel between the servers and the sensors to guarantee the rightness of the gathered data. If the gathered data is corrupted, the data analysis outcomes are unreliable and can lead to even more catastrophic damage. This paper suggests a solution to the problem by introducing two-tier cryptography using ciphertext shifting with HMAC-SHA1 signature and token-based access control for safe and proficient data transmission in the IoT. In Tier-1, Secret-key cryptography with ciphertext shifting technique encrypts data sensed by IoT devices. In Tier-2, Public-key cryptography with a ciphertext shifting technique is used to encrypt a ciphertext once again, which the IoT base station receives from each IoT device. Then IoT base station transmits this ciphertext to the administrator. Additionally, a token-based access control technique allows only the administrator with the token of the sender IoT device to access the received ciphertext.Furthermore, the HMAC-SHA1 signature is used to verify whether the received ciphertext is safe. The proposed cryptography technique simultaneously achieves confidentiality, integrity, authentication, access control and anonymity. The experimental result shows the two-tier cryptography technique is faster and more energy-efficient than existing techniques.
