An Extended Protected Secret Sharing Scheme

2022

Preprint

As a result of the rapid developments in digital technologies, smart cities have been adorned with several digital gadgets based on the Internet of Things (IoT). The essential part of smart cities operations is IoT communications. IoT devices generate, process, and exchange a large amount of security-critical and privacy-sensitive data regularly, resulting in attractive targets for threats and attacks. Group-oriented communication plays a critical role in the IoT world, such as data gathering and area monitoring. The lower time complexity of Group-based authentication (GBA) makes these protocols very popular for efficient and secured communication. This paper uses a polynomial-based group authentication scheme and membership verification to ensure efficient and threat-free communication among IoT devices. Furthermore, a Bi-variate polynomial is used instead of the single variable polynomial to add the novelty of the work. Along with novelty, the protected nature of the bi-variate polynomial makes the proposed scheme very secure and reliable. Security analysis of the proposed work shows its efficiency over existing schemes.

“…To establish secret communication keys for shareholders. • Proposed scheme uses bi-variate polynomial as in [20]- [22], which makes this schemes very light as compared to others because it eliminates the requirement of extra key generation for the exchange of tokens among the nodes. The rest of the article comprises related works in section II, followed by preliminaries and proposed protocol in sections III and IV.…”

As a result of the rapid developments in digital technologies, smart cities have been adorned with several digital gadgets based on the Internet of Things (IoT). The essential part of smart city operations is IoT communications. IoT devices generate, process, and exchange a large amount of security-critical and privacy-sensitive data regularly, resulting in attractive targets for threats and attacks. Group-oriented communication, such as data gathering and area monitoring, is critical in the IoT World. It enables users to manage various IoT devices simultaneously. Conventional one-to-one authentication techniques donot consider the resource constraints of IoT devices in grouped communication. They also do not solve the issue of massive machinecommunication (mMTC) scalability. Many to Many (M2M)authentication approach of group authentication makes grouporientedcommunication and mMTC very secure. The lower timecomplexity of Group-based authentication (GBA) makes theseprotocols very popular for efficient and secured communication.This paper uses a polynomial-based group authentication schemeand membership verification to ensure efficient and threat-freecommunication among IoT devices. Bi-variate polynomials havebeen used instead of single variable functions in the proposedscheme. The protected nature of the bi-variate polynomial makesthe proposed scheme very secure and reliable. Furthermore,establishing the session key makes the proposed scheme effectiveand efficient. Security analysis of the proposed work shows itsefficiency over existing schemes.
