The Centre for Hardware Security conducts research in all applied aspects of hardware security: the aim is to validate security techniques in real silicon. The Centre's research on integrated circuit (IC) design, electronic design automation (EDA), and cryptographic hardware enables trustworthy IC-based systems to be built. Threats such as hardware Trojans, reverse engineering, circuit (de)obfuscation, IP piracy, IC overbuilding, side-channel attacks, etc., are addressed through an array of technical countermeasures. The centre was established in late 2019. 

Head of the centre: prof. Samuel Nascimento Pagliarini

Core competences:

• Design of Application Specific Integrated Circuits
• Circuit obfuscation by design partitioning (Split-Chip and Split-Fab)
• Trustworthy electronic design automation tooling (from RTL to layout)
• Countermeasures to reverse engineering, side channel attacks, and piracy
• Crypto hardware
