Electromagnetic analysis attack for a lightweight cipher PRINCE
Masaya Yoshikawa, Yusuke Nozaki · 2016
Ensuring the security of built-in apparatuses has become an important task because of advancements in Internet of Things (IoT) technology. Therefore, lightweight ciphers that are available in built-in apparatuses have attracted the attention of many researchers. However, the danger of electromagnetic analysis attacks against cryptographic circuits has been pointed out. Electromagnetic analysis attacks illegally analyze confidential information using the electromagnetic waves that are generated during the operation of a cryptographic circuit. Many studies have reported on power analysis attacks against the advanced encryption standard (AES). However, as far as we know, no study has reported on electromagnetic analysis attacks against PRINCE, which is one of the most popular lightweight ciphers. The present study proposes a method for electromagnetic analysis attacks against PRINCE in order to evaluate the tamper resistance of PRINCE. The present study also verifies the validity of the proposed method by performing an evaluation experiment using a field-programmable gate array (FPGA).
