13.56 MHz passive electron tag for smart card application with high-security

Information security is the core issue need to be resolved in RF communication. In accordance with ISO/IEC 14443-A protocol, this paper accomplished the design and implementation of 13.56 MHz passive electron tag for smart card with high-security. Using the HHNEC 0.13 um process, the gate count of RF digital circuit is about 7833 and the smart card chip area is 8.08 mm2. Encrypting the communication and memory data through hardware with the feature of anti-side-channel attacks, the encryption modules DES/3DES, could ensure the card security of information transaction. On the basis of high-security, the results show the chip achieved a good balance among the speed, area and power consumption, which could be well applicable to public transport, e-commerce, financial field and so on.
