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.

A symmetric group key agreement protocol enables the group members to derive a shared session key for secure communication among them, whereas an asymmetric one facilitates security to any communication from outside, without adding outsiders into the group. In order to combine both the functionalities, a hybrid key agreement protocol is needed, which can output a shared symmetric key for inside communication and an asymmetric key pair for any unrestricted sender. The application mentioned in this paper pushes the need of secure on-chip communication for intersecure and intrasecure zones simultaneously. In particular, we look forward for a solution to ensure communication security among multiple processing clusters actively running on an integrated circuit.The proposed protocol offers a lightweight symmetric encryption for intrazone communication and a public key encryption for interzone communication taking most advanced security issues into account.An extended abstract of this contribution has already been published 1 at Privacy, Security & Trust (PST) 2018.

Abstract-Mobile communications have grown exponentially these last few years leading to an increasing demand. SoftwareDefined Networking appears to be a promising technology in order to provide flexible Quality of Service and very low latency. By modifying the 4G LTE architecture and integrating OpenFlow (SDN protocol) towards the 5G architecture, this new architecture promises to fulfill the requirements and to achieve better performances while participating to the network functions virtualization.
