Sony announced today that after final ISO/IEC approval, CLEFIA –the Sony developed block cipher algorithm was adopted as one of the ISO/IEC 29192 International Standards in lightweight cryptography. CLEFIA has the same interface as the US government’s Advanced Encryption Standard (AES). This block cipher has a block length of 128 bits, while key length can be selected from 128 bits, 192 bits or 256 bits. The most impressive feature of ‘CLEFIA’ is its realization of implementation efficiency while maintaining a high level of security.
This excellent implementation efficiency enables CLEFIA to demonstrate high performance in devices with limited resources or those with low-power consumption requirements. Accordingly, CLEFIA is suited for lightweight cryptographic applications as indicated in ISO/IEC 29192 in smartcards, RFID tags, sensor networks, medical devices and more, in addition to conventional applications. Through its efforts, Sony will continue to be involved in delivering information security technology that customers can use safely and with confidence.
