As the number of processing cores is increasing dramatically, the communication among them is of high importance. Network-on-Chip (NoC) has direct access to all resources and information within a System-on-Chip (SoC) by rendering it appealing to attackers. In this paper a novel Hardware Trojan (HT) assisted Denial of Service (DoS) attack, called Greyhole attack is introduced. The HT-Greyhole attack targets the routers within NoC by causing performance decrease and packet loss increase. However, during an HT-Greyhole attack certain packets, which are arriving towards the router, are dropped which makes it hard to detect. In this paper, we design a detection and defense method, against HT-Greyhole attack, which is based on Software Defined Network-on-Chip (SDNoC) architecture. The results demonstrate that by using the proposed defense method the packet loss decreases by 76% under Transpose traffic, 77% under BitReverse and 50% under Uniform traffic.

In recent years, Multi-Processor System-on-Chips (MPSoCs) are widely deployed in safety-critical embedded systems. The Cloud-of-Chips (CoC) is a scalable MPSoC architecture comprised of a large number of interconnected Integrated Circuits (IC) and Processing Clusters (PC) destined for critical systems. While many researches have focused on addressing the hardware issues of MPSoCs, the communication over them has not been very well explored. Following the SDN concept, we propose a new protocol in order to secure the communication and efficiently manage the routing within the CoC. The SSPSoC includes a private key derivation phase, a group key agreement (GKA) phase, and a data exchange phase in order to ensure that basic security primitives are preserved and provide secure communication. Furthermore, a network of 1-30 nodes is set in order to validate the proposed protocol and measure the network performance and memory consumption of the proposed protocol.

The increasing integration on latest MPSoC devices invites various security threats. To execute a sensitive application, a combination of IP cores on an MPSoC platform creates a security zone. This security zone must be protected. In this paper, we attempt to achieve the secure communication among these security zones supported by a two party key agreement protocol. Furthermore, we extend this idea to cover both varieties of security zones: continuous as well as disrupted.

A symmetric group key agreement protocol enables the group members to derive a shared session key for secure communication among them, while an asymmetric one facilitates security to any communication from outside, without adding outsiders into the group. In this paper, we propose a twofold group key agreement protocol which addresses the need of a shared symmetric key among insider members in a group and an asymmetric key pair for any unrestricted sender. In particular, we look forward for a solution to provide secure communication among multiple processing clusters (PCs) actively running on an integrated circuit (IC). The proposed protocol offers a lightweight symmetric encryption for intra zone communication and a public key encryption for inter zone communication taking most advanced security issues into account.

System on chips (SoCs) are all around us in today's world. Therefore, in this paper we propose a flexible, technology-aware SoC design, named as Cloud-of-Chips (CoC), which is able to change its characteristics, such as routing logic, transmission paths, priorities, IC clustering, etc. We focus particularly on inside communication of CoC architecture. The basic idea of CoC is the creation of an architecture, which will be able to support all the requirements of a vast number of todays applications by adopting and changing its characteristics according to them. The valorization perspectives are of importance since the outcomes of this research will be applicable for embedded systems, real-time systems, communication systems, as well as for mainstream systems such as Internet-of-Things and Internet-of-Everything. As far as the inside communication of our CoC platform is concerned, we leverage on algorithms and strategies developed within the field of Software Defined Networking (SDN), which was introduced to deal with hardware redesign and ultimately provide cloud-like flexibility. At the end, we describe registration and authentication of every entity in our network.

Modern irrigation systems utilize sensors and actuators, interconnected together as a single entity. In such entities, A.I. algorithms are implemented, which are responsible for the irrigation process. In this paper, the authors present an irrigation Open Watering System (OWS) architecture that spatially clusters the irrigation process into autonomous irrigation sections. Authors’ OWS implementation includes a Neuro-Fuzzy decision algorithm called FITRA, which originates from the Greek word for seed. In this paper, the FITRA algorithm is described in detail, as are experimentation results that indicate significant water conservations from the use of the FITRA algorithm. Furthermore, the authors propose a new communication protocol over LoRa radio as an alternative low-energy and long-range OWS clusters communication mechanism. The experimental scenarios confirm that the FITRA algorithm provides more efficient irrigation on clustered areas than existing non-clustered, time scheduled or threshold adaptive algorithms. This is due to the FITRA algorithm’s frequent monitoring of environmental conditions, fuzzy and neural network adaptation as well as adherence to past irrigation preferences.
