“…Para suportar esse serviço na interface de rede XIRU, devem ser implementados buffers separados para pacotes RT e nRT e um escalonador que priorize os pacotes do buffer RT. Já em [17] foram implementados wrappers de hardware que filtram pacotes de tráfegos maliciosos que tentam degradar a disponibilidade da rede SoCIN. Esses wrappers podem ser facilmente integrados à interface XIRU, posicionados logo após o buffer de saída da camada Rede.…”

Para a integração dos núcleos de um sistema integrado a uma NoC (Network-on-Chip), é necessário o uso de interfaces de comunicação que realizem a adaptação do protocolo dos núcleos ao da rede e que ofereçam os serviços de comunicação necessários aos núcleos. Este artigo descreve a arquitetura de uma interface de rede extensível para a integração de núcleos à NoC SoCIN (System-on-Chip Interconnection Network). A interface proposta utiliza uma arquitetura estruturada em três camadas que realizam a adaptação do protocolo, o empacotamento/desempacotamento de dados e o envio/recepção de pacotes, entre outros serviços. O artigo descreve a arquitetura da interface de rede e apresenta os resultados de sua validação e síntese em silício.

Next to performance, it becomes increasingly important that Networks-on-Chip (NoCs) also provide security features such as access control, authentication and availability. They are usually implemented by firewalls at the network interfaces (NIs) of the processing elements (PEs). This paper provides a more efficient way to integrate these security requirements into application-specific NoCs by inserting firewalls also between NoC routers. This approach helps to reduce the communication overhead required for the security information in the packet headers, which can consume 3% to 9% of the total communication bandwidth. It is challenging to manually find the optimal firewall configuration because an application-specific NoC has an irregular topology, which is customized for certain known application, e.g. a smartphone chip. Thus, we show how to automatically solve this problem by formulating it as an Integer Linear Programming (ILP) problem. The solution results in firewall positions such that the communication overhead is minimized and all given security requirements are satisfied. Experiments are performed on two industrial system specifications. Compared to the solution with the firewalls at the NIs, communication overhead is reduced by up to 63%. The optimization only takes a few seconds for a standard ILP solver.

Traffic hijacking is a common attack perpetrated on networked systems, where attackers eavesdrop on user transactions, manipulate packet data, and divert traffic to illegitimate locations. Similar attacks can also be unleashed in a NoC (Network on Chip) based system where the NoC comes from a third-party vendor and can be engrafted with hardware Trojans. Unlike the attackers on a traditional network, those Trojans are usually small and have limited capacity. This paper targets such a hardware Trojan; Specifically, the Trojan aims to divert traffic packets to unauthorized locations on the NoC. To detect this kind of traffic hijacking, we propose an authentication scheme in which the source and destination addresses are tagged. We develop a custom design for the packet tagging and authentication such that the implementation costs can be greatly reduced. Our experiments on a set of applications show that on average the detection circuitry incurs about 3.37% overhead in area, 2.61% in power, and 0.097% in performance when compared to the baseline design.
