Abstract :
Lightweight block ciphers, which can be embedded using small area, have attracted much attention. This study proposes a new countermeasure for TWINE which is one of the most popular light weight block ciphers. The proposed method masks the correlation between power consumption and confidential information by adding random numbers to intermediate data of encryption. Experiments prove effective tamper-resistance of the proposed method.
