An Efficient Digital Short Signature Scheme using CCM for HC-IoT Environments

With billions of life-improving applications proliferating the global space, the Human-Centered Internet of Things (HC-IoT) grips excellent promise. The Internet will comprise more than 50 billion linked things, comprising mobile devices, GPS devices, sensors, actuators, and all the smart things that can be imagined. The HC-IoT comprises many smart gadgets to distribute identified information via online platforms. The goal is to encrypt messages between the sender and receiver during data exchange with the right instruction to challenge any human malicious attack. Different signature-based schemes have been proposed to ensure secure communication of critical user information. Smart gadgets claim lightweight characteristics, posing remarkable strengths and safety. The core challenge with signature-based techniques is the incurred computational cost owing to the enormous resources required for signature and verification procedures. The current paper projects an efficient Digital Short Signature (DSS) Scheme that uses Conformal Chaotic Maps (CCM) for protected communication in HC-IoT-based smart devices. The security of the projected scheme is thoroughly connected to a CCM in the random oracle model (ROM). The proposed DSS-CCM scheme offers more security assurance than the existing signature systems. The presented scheme would find practical applications in smart cards and emerging wireless security systems.
