“…In contrast, Kasinathan et al [67] proposed an architecture to protect IoT based 6LoWPAN devices against DoS attacks as well as jamming and tampering attacks in the context of the European project called ebbits 11 . The main contribution is twofold: first, the design of Intrusion detection manager that is charged to protect constrained devices against DoS attacks.…”

“…Recently, several attempts have been investigated to address this issue. Mixing protocols [11,15,125] are considered as efficient techniques to fix this problem. The main idea behind these approaches is to provide mechanisms that allow users to send and receive transactions in such a way it's difficult for an attacker to find out the correspondence between input and output addresses of the same user.…”

Internet of Things (IoT) is one of the promising technologies that has attracted a lot of attention in both industrial and academic fields these years. It aims to integrate seamlessly both physical and digital worlds in one single ecosystem that makes up a new intelligent era of Internet. This technology offers a huge business value for organizations and provides opportunities for many existing applications such as energy, healthcare and other sectors. However, as new emergent technology, IoT suffers from several security issues which are most challenging than those from other fields regarding its complex environment and resources-constrained IoT devices. A lot of researches have been initiated in order to provide efficient security solutions in IoT, particularly to address resources constraints and scalability issues. Furthermore, some technologies related to networking and cryptocurrency fields such as Software Defined Networking (SDN) and Blockchain are revolutionizing the world of the Internet of Things thanks to their efficiency and scalability. In this paper, we provide a comprehensive top down survey of the most recent proposed security and privacy solutions in IoT. We discuss particularly the benefits that new approaches such as blockchain and Software Defined Networking can bring to the security and the privacy in IoT in terms of flexibility and scalability. Finally, we give a general classification of existing solutions and comparison based on important parameters.

“…For instance with the fast certificate revocation, blockchain-based PKIs can instantaneously isolate the infected CA and the corresponding certificates without the need to wait until the next update of Certificate Revocation Lists (CRLs). Also, blockchain-based PKI, as a public append-only log, naturally provides the certificate transparency (CT) property proposed by Google [9].…”

“…Blockchain-based PKI inspired many studies [8], [9], [10] proposing blockchain technology to build secure PKI systems. Their main argument is that blockchain-based solution can merge the benefits of the Log-based PKIs and the WoT approaches, and solve some of the problems with conventional PKI system.…”

Abstract-Public-Key Infrastructure (PKI) is the cornerstone technology that facilitates secure information exchange over the Internet. However, PKI is exposed to risks due to potential failures of Certificate Authorities (CAs) that may be used to issue unauthorized certificates for end-users. Many recent breaches show that if a CA is compromised, the security of the corresponding end-users will be in risk. As an emerging solution, Blockchain technology potentially resolves the problems of traditional PKI systems -in particular, elimination of single point-of-failure and rapid reaction to CAs shortcomings. Blockchain has the ability to store and manage digital certificates within a public and immutable ledger, resulting in a fully traceable history log. In this paper we designed and developed a blockchain-based PKI management framework for issuing, validating and revoking X.509 certificates. Evaluation and experimental results confirm that the proposed framework provides more reliable and robust PKI systems with modest maintenance costs.

“…From this root element, it branches through a hierarchical certificate chain, where any certificate signed by a trusted certificate is consequently trusted. [7] Considering that most of the PKI's basic are directly related to PGP's concepts, one other convectional approach is based on the Web of Trust definition. Unlike the previously mentioned CA-based PKI, the trust becomes decentralized.…”

The Internet of Things is progressively getting broader, evolving its scope while creating new markets and adding more to the existing ones. However, both generation and analysis of large amounts of data, which are integral to this concept, may require the proper protection and privacy-awareness of some sensitive information. In order to control the access to this data, allowing devices to verify the reliability of their own interactions with other endpoints of the network is a crucial step to ensure this required safeness. Through the implementation of a blockchain-based Public Key Infrastructure connected to the Keybase platform, it is possible to achieve a simple protocol that binds devices' public keys to their owner accounts, which are respectively supported by identity proofs. The records of this blockchain represent digital signatures performed by this Keybase users on their respective devices' public keys, claiming their ownership. Resorting to this distributed and decentralized PKI, any device is able to autonomously verify the entity in control of a certain node of the network and prevent future interactions with unverified parties.
