Q and A
- Q:
- What is the origin of the name "CLEFIA"?
- A:
- It has been named after the French word "Clef" meaning "key."
- Q:
- What are the applications for this technology?
- A:
- It can be applied in any product or software that requires encryption and authentication. In particular, CLEFIA can be implemented efficiently in restricted environments such as smartcard and RFID applications.
- Q:
- What is the advantage over the existing block ciphers?
- A:
- CLEFIA achieves compact and fast implementation simultaneously without compromising security. Compared with the AES, the most-widely-used 128-bit block cipher, CLEFIA is advantageous in hardware implementation. Using a 0.09 micrometer CMOS ASIC library, CLEFIA can be implemented with less than 5 Kgates -- the smallest size ever. Furthermore, CLEFIA realizes a speed of 1.6 Gbps at less than 6 Kgates, with throughput per gate also the world's highest.
