T-TRAIL: Preventing Decreased Rank Attacks in RPL-based IoT Networks

The Routing Protocol for Low-Power and Lossy Networks (RPL) has gained in popularity since the increased connectivity of everyday items to the Internet. One of the discovered attacks on RPL is the rank attack, which opens up possibilities for attackers to control traffic in the RPL network by spoofing their priority. Many solutions have been...

A Comparative Study on Signature Schemes for IoT Devices

The use of Internet of things (IoT) devices is on the rise and given their involvement with sensitive data the security for these devices is of greater importance. As these devices are connected with the internet being able to have secure communication is crucial. Some of the major aspects for secure communication are identification and message...

A Comparative Study of the TEA, XTEA, PRESENT and Simon lightweight cryptographic schemes

With the current fast paced growth in the number of devices connected to the internet, many of these having limited computational capability, security concerns are of increasing importance. To meet the necessity of providing secure encryption to constrained devices many lightweight cryptographic schemes have been developed. This paper provides a...

RPL Attack Analysis: Evaluation of a Cryptography-Based Sybil Defence in IEEE 802.15.4

While the Routing Protocol for Low Power and Lossy Networks (RPL) is built to support the constraints of low-powered devices, it struggles to meet the standards in security. Generally, low-powered devices are challenged with limited cryptography, tough key management, and interoperability issues. Despite these concerns, security is not only...

STIR: Preventing Routing Table Overload Attacks in RPL-based IoT Networks

Routing Protocol for Low Power and Lossy Networks (RPL) is a routing protocol for Internet of Things (IoT) devices with limited resources. As IoT is becoming prevalent, it is important to secure the underlying protocols that compose it such as RPL. This paper sought to avoid an RPL-specific routing attack by modifying the protocol's...

The performance of the routing protocol for low-power and lossy networks in mobile networks

The IPv6 routing protocol for low-power and lossy networks (RPL) is a routing protocol that is standardized for constrained devices. This standard only considers static nodes and consequently underperforms in networks with moving nodes. Several studies exist intending to mend this problem, but analyses of RPL's performance in mobile situations...

Blockchain-based DNS and PKI to solve issues of trust, security and censorship in the context of the IoT

The domain name system (DNS) and public key infrastructure (PKI) provide the core services for the Internet. The use of these systems requires trust in institutions to provide proper services, which they can fail to provide. Centralized management allows these institutions to perform censorship. Additionally, these legacy systems have seen...

Blockchain-based frameworks for mitigating DDoS and Sybil attacks in the IoT

With the growing scale of the IoT, many industries enjoy the benefit of automation. The IoT consists of an interconnected network of devices that sense their surroundings and share data among other IoT devices. However, this data can be sensitive and private in nature, making security within the ever-growing IoT network a high priority. Because...

Improving data integrity and fault tolerance in IoT networks with Blockchain: on the search for suitable consensus mechanisms

IoT devices have grown rapidly over the past few years. IoT devices are mostly connected to a central server that stores the data and handles end-to-end communication. Due to the increase of IoT devices, the latency with the server increases. Furthermore, when using a central server the data is at risk of being deleted or tampered with. To...
