The widespread of electronics systems developed as SoC (system-on-chip) in distributed environment, allows the critical information stored by SoCs to be target of attacks. In such scenario, security is becoming an important system design requirement of current SoCs. Communication structure is the heart of the SoC. Its main role in the information exchange and control turns the communication structure an attractive alternative to implement security services. Recently, HoCs (Hybrid-on-chip) communication structures have been proposed. It combines NoCs (Network-on-Chip) and buses in order to meet the communication requirements of current and future SoCs. The challenge is to guarantee the SoC security under tight area, latency and power constraints. The QoSS (Quality-of-Security-Service) adoption at HoC design allows the exploration between system performance and security. For the best of our knowledge this is the first attempt to implement security at HoCs. The French LabStiCC security group directed by Prof. Guy Gogniat is a reference in the area of embedded system protection. In the internship of 1 year at such laboratory we are going to: 1) test and integrate the SystemC-TLM bus model, SECA, that implements security service, to our SystemC-TLM NoC model; 2) Use the cryptoprocessor models to implement different HoC security services; 3) Use the attacks generators to develop and to refine the HoC security mechanism and to test its efficacy; 4) develop protection solutions for systems characterized by dynamic security policy; and 5) integrate our HoC to their MPSoC model. In the past, the partnership between LABSTICC and our laboratory produced 3 conference papers, 2 journal papers and 2 indications as best conference paper. (AU)
