Systems-on-chip (SoCs) based on many core architectures can be attacked. Malicious processes can infer secrets from on-chip sensible traffic by evaluating the degradation on their communication performance. Such a threat rises from the resource sharing. In order to avoid such time-driven attacks, the network-on-chip (NoC) can integrate mechanisms to isolate(More)
Three-dimension Multiprocessors System-on-Chip (3D-MPSoCs) hold promises to allow the development of compact and efficient devices. By means of such technology, multiple applications are supported on the same chip, which can be mapped dynamically during the execution time. This flexibility offered by the 3D technology, also represents vulnerability, turning(More)
MPSoCs have been proposed as a promising architecture choice to overcome the challenging embedded electronics requirements, characterized by tights development times and fast evolution of applications. The MPSoC flexibility, also represents a system vulnerability. As security requirements vary dramatically for different applications, the challenge is to(More)
3D-MPSoCs integrate cores of several vendors and support different applications on a single die, providing large performance and cost reduction. 3D-technology presents many security challenges and offers new opportunities to implement protection countermeasures. 3D-NoCs can be explored to assist the overall security of the system. In this work, we propose a(More)
The wide use of Multi-processing systems-on-chip (MPSoCs) in embedded systems and the trend to increase the integration between devices have turned these systems vulnerable to attacks. Malicious software executed on compromised IP may become a serious security problem. By snooping the traffic exchanged through the Network-on-chip (NoC), it is possible to(More)
Embedded systems are parts of our daily life and used in many fields. They can be found in smartphones or in modern cars including GPS, light/rain sensors and other electronic assistance mechanisms. These systems may handle sensitive data (such as credit card numbers, critical information about the host system and so on) which must be protected against(More)
Current SoC design trends are characterized by the integration of larger amount of IPs targeting a wide range of application fields. Such multi-application systems are constrained by a set of requirements. In such scenario network-on-chips (NoC) are becoming more important as the on-chip communication structure. Designing an optimal NoC for satisfying the(More)
