As RFID chips and smart cards become pervasive, the need for strong security measures will increase. At the Sakamura Laboratory, we have developed an architecture that seeks to provide a type of lock-and-key protection to distributed systems. This architecture securely stores information used in a commercial transaction and exchanges information via the digital information infrastructure. A tamper-resistant chip is at the core of this architecture, called eTRON (Entity TRON). The authors outline the eTRON research project.
