“…The approach we propose in this paper improves the ones reported in this section under several aspects. First of all, it is more general because it does not assume any specific network topology such as that in the work of Hummen et al nor the use of uncommon certificate formats and schemes like in other works . Indeed, although in this work we propose a new type of certificate to further improve the performances of the proposed solution, its use is not mandatory, and this enables an easy interoperability of the proposed architecture with already deployed systems.…”

“…16 With implicit certificates, on the other hand it is possible to obtain certificates that are up to 57 times smaller than standard certificates, and whose verification requires lightweight operations. 17 In the work of Sciancalepore et al, 18 implicit certificates are used to exchange the public coefficients of the widely adopted ECDH key exchange protocol reducing this way up to 86.7% the airtime consumption if compared with traditional approaches. Ting et al 19 proposed to avoid the use of certificates in the IoT segment by resorting to identity-based cryptography techniques, which link meaningful strings to private keys by means of a trusted private key generator.…”

Internet of Things (IoT) nodes participating in the implementation of next‐generation IoT applications will need standard methods to authenticate each other and secure their communications. However, the use of certificates and public key infrastructure (PKI) technologies, widely employed in the Internet, is not straightforward in this context because of the limitations of the involved entities. This paper presents the public key infrastructure for the Internet of Things (PKIoT) architecture, a solution which aims at enabling certificate‐based authentication in the forthcoming IoT scenarios by allowing the flexible outsourcing of the most demanding security‐related tasks and by introducing a new type of compact certificate. This paper also highlights the role that this architecture can play in the context of the oneM2 M security framework in enabling standard secure machine‐2‐machine interactions. In conclusion, this paper reports the results of the conducted experiments, which show the effectiveness of the proposed approach in reducing the execution time and the energy consumption of certificate‐based session establishment for Datagram Transport Layer Security up to 78% and 89% respectively, fostering this way standard and secure IoT transactions.

“…We evaluated the possibility of adding forward secrecy to the MAC‐layer security. Perfect forward secrecy could be achieved using elliptic‐curve Diffie‐Hellman ephemeral (ECDHE) as performed by Sciancalepore et al in a wireless network. This requires a one round‐trip handshake and thus could be embedded in join‐request and join‐accept messages.…”

This paper introduces a fully decentralized low-power wide-area network (LPWAN) infrastructure for the Internet of things (IoT) using the LoRa protocol. While global LPWANs typically require roaming agreements between network providers and a trusted third party for server resolution, we propose a trustless model where the network servers are resolved using a blockchain application. Since LoRaWAN relies on symmetric cryptography, we also propose a new security model that adds non-repudiation using digital signatures. This paves the way for linking devices to decentralized applications. We finally analyze the impact of this new model on message size and energy requirements. KEYWORDS blockchain, distributed systems, Internet of Things, LoRaWAN INTRODUCTIONLow power communication is a major milestone for the Internet of Things (IoT). Low-Power Wide-Area Network (LPWAN) technologies seek to provide a large coverage area and a long battery life at the cost of reduced bandwidth compared to legacy cellular networks. LTE network carriers are actively upgrading to newer standards such as NB-IoT or LTE-M to fill this gap. However, this type of service is restricted to telecom operators buying expensive licences in order to use cellular frequencies. A promising alternative is LPWAN running on unlicensed frequency bands. This is characterized by long-range sub-gigahertz radio links and star topologies. 1 In addition to services offered by network providers, unlicensed bands enable individuals and organizations to run their own network without a third party. This creates a rich ecosystem where organizations can build conglomerates of networks in order to reach a wider potentially global coverage. Similarly, it is possible to crowd-source parts of the network such as radio gateways, transceivers that sit between end-devices and a wide area network. An example of such a network isThe Things Network (TTN), 2 a global LoRaWAN data network that leverages radio gateways provided by its community. In TTN, gateways belong to users while network backend servers are managed by TTN itself. We push the crowd-sourced idea further by trying to build a global and fully decentralized IoT network. Among the advantages of a decentralized network are a high resilience against many threats and improved scalability.We propose a solution based on the LoRaWAN protocol and build a prototype of a decentralized IoT network using a blockchain-connected packet forwarding application and off-the-shelf hardware. There have been previous attempts to conceptualize such a decentralized network, 3 but to the best of our knowledge, we released the first practical implementation of such a system using LoRaWAN. 4 Bezahaf et al then proposed an alternative LoRa scheme that solves the fair exchange problem, 5 which is complementary to our previous work. Blockchain technology is a key element of the system, since it makes it possible to build a shared globally synchronized key-value store of network ''join'' servers without the involvement of a trusted party.

“…Therefore, encryption schemes for IoT systems need to be less complicated, and should function with reduced memory usage, which is dependent on the key size. Compared to conventional systems, elliptical curve cryptography (ECC) can statistically provide stronger security with a smaller key size, thus making it a suitable alternative for IoT devices . The strength of elliptical cryptography relies on the fact that the output of the decryption operation will be ambiguous without a proper authentication key.…”

Elliptic curve cryptography (ECC) can achieve relatively good security with a smaller key length, making it suitable for Internet of Things (IoT) devices. DNA-based encryption has also been proven to have good security. To develop a more secure and stable cryptography technique, we propose a new hybrid DNA-encoded ECC scheme that provides multilevel security. The DNA sequence is selected, and using a sorting algorithm, a unique set of nucleotide groups is assigned. These are directly converted to binary sequence and then encrypted using the ECC; thus giving double-fold security. Using several examples, this paper shows how this complete method can be realized on IoT devices. To verify the performance, we implement the complete system on the embedded platform of a Raspberry Pi 3 board, and utilize an active sensor data input to calculate the time and energy required for different data vector sizes. Connectivity and resilience analysis prove that DNAmapped ECC can provide better security compared to ECC alone. The proposed method shows good potential for upcoming IoT technologies that require a smaller but effective security system.
