Side-channel Attack Standard Evaluation Board (SASEBO)

Standard Cryptographic LSIs

This cryptographic LSI was fabricated with a 130-nm TSMC standard cell library. ISO/IEC 18033-3 standard block ciphers AES, Camellia, SEED, MISTY-1, CAST-128, a defact standard DES, and a public-key cipher RSA are supported. The key size for export version is limited as 56 bits for block ciphers and 512 bits for RSA.


Two cryptographic LSIs fabricated with 90-nm and 130-nm TSMC standard cell libraries support elliptic curve cryptography as well as the ISO/IEC 18033-3 standard block ciphers and RSA. Seven AES circuits with side channel attack countermeasures are also integrated on the LISs.


This report provids experimental results of various power analysis attacks on the AES and RSA circuits, in which the cryptographic LSI on SASEBO-R and the Xilinx FPGA on SASEBO-G were used.
