RC-SA21 4KB AES IC Chip
- EAL6+ Common Criteria
- Extended Overlap Service / Additional security options
The RC-SA21 FeliCa Standard SD2 contactless IC chip provides backward compatibility with existing FeliCa Standard IC chip products (RC-SA01 series), while adding several new features, such as Extended Overlap Service and additional security options.
The IC chip supports Advanced Encryption Standard (AES) and has acquired Common Criteria (ISO/IEC 15408) EAL6+ certification.
* FeliCa Standard SD2：The 2nd generation of the IC chips and their products of FeliCa Standard products which support AES encryption.
Highest level of security for contactless smartcard IC chips
The IC chip supports the AES encryption method and provides high security. With its state-of-the-art tamper-resistant technology, it has acquired the very high assurance level of EAL6+, in accordance with ISO/IEC 15408 Common Criteria certification, an international standard for security. The IC chip also complies with Public Transportation IC Card Protection Profile (PTPP).
Multi-application platform with higher performance and reliability
Higher transaction speed is achieved for every type of card application, such as transportation ticket and e-payment. In addition, the IC chip achieves lower power consumption than the current FeliCa IC chips.
The Error Checking and Correcting (ECC) functionality improves the reliability of non-volatile memory data.
Communication with NFC Forum-compatible readers
The chip complies with Type 3 Tag functionality defined by the NFC Forum. Therefore, a card with the chip can communicate with NFC-compatible smartphones and readers.
Additional security options to meet market needs
In addition to the encryption and integrity protection of communication data in the current secure communication function, a security option that supports only integrity protection of communication data has been added. This extends the choice of cost-balanced system solutions for use cases where higher priority is given to high-speed transactions, while meeting the required security needs.
Extended Overlap Service
This feature allows different service providers to share additional services, while making the most of existing systems.
Value-Limited Purse Service
Value-Limited Purse Service enables the purse data to be set as a negative numerical value, and enables "Upper Limit Value" and "Lower Limit Value" to be specified.
