Reusable Mesh Signature Scheme for Protecting Identity Privacy of IoT Devices

Abstract

The development of the Internet of Things (IoT) plays a very important role for processing data at the edge of a network. Therefore, it is very important to protect the privacy of IoT devices when these devices process and transfer data. A mesh signature (MS) is a useful cryptographic tool, which makes a signer sign any message anonymously. As a result, the signer can hide his specific identity information to the mesh signature, namely his identifying information (such as personal public key) may be hidden to a list of tuples that consist of public key and message. Therefore, we propose an improved mesh signature scheme for IoT devices in this paper. The IoT devices seen as the signers may sign their publishing data through our proposed mesh signature scheme, and their specific identities can be hidden to a list of possible signers. Additionally, mesh signature consists of some atomic signatures, where the atomic signatures can be reusable. Therefore, for a large amount of data published by the IoT devices, the atomic signatures on the same data can be reusable so as to decrease the number of signatures generated by the IoT devices in our proposed scheme. Compared with the original mesh signature scheme, the proposed scheme has less computational costs on generating final mesh signature and signature verification. Since atomic signatures are reusable, the proposed scheme has more advantages on generating final mesh signature by reconstructing atomic signatures. Furthermore, according to our experiment, when the proposed scheme generates a mesh signature on 10 MB message, the memory consumption is only about 200 KB. Therefore, it is feasible that the proposed scheme is used to protect the identity privacy of IoT devices.

Out of Control – Privacy Calculus and the Effect of Perceived Control and Moral Considerations on the Usage of IoT Healthcare Devices

“…The restriction of data collection is also addressed by article 25 of the GDPR 3 . At the same time, new privacy protection tools evolve, which actively prevent identification through IoT networks, e.g., by means of cryptography ( Gu et al, 2020 ) or are able to detect privacy intrusion or attacks (for review on network intrusion detection systems see Chaabouni et al, 2019 ).…”

Chaos-Based Application of a Novel Multistable 5D Memristive Hyperchaotic System with Coexisting Multiple Attractors

“…With the development of communication technology and the coming of information age, people are more and more aware of the important role of information security [71][72][73][74][75][76], and the research of various security protection has become the current research hotspot [77][78][79][80][81][82]. As an important part of information security transmission, random number generator (RNG) has been paid more and more attention.…”

Energy-aware MAC protocol for data differentiated services in sensor-cloud computing

“…Under duty cycle-based MAC protocol, the length of a duty cycle influences delays most. Usually, the proportion of awake time is greater and delays are shorter, but energy consumption is higher [52][53][54][55].…”
