Electromagnetic analysis attack for a lightweight block cipher TWINE

The threat of electromagnetic analysis attacks against cryptographic circuits has been highlighted. Electromagnetic analysis attacks maliciously analyze confidential information using electromagnetic waves generated during the operation of a cryptographic circuit. At present, many studies have reported on electromagnetic analysis attacks against AES. However, few studies have investigated electromagnetic analysis attacks against lightweight ciphers. To secure the safety of a device to which a lightweight cipher is applied, measures against electromagnetic analysis attacks must be developed. To examine the measures taken to prevent electromagnetic analysis attacks, it is important to first evaluate and verify the vulnerability of a lightweight cipher against those types of attacks. This study propose a new electromagnetic analysis attack for a lightweight block cipher TWINE which is one of the most popular lightweight block ciphers.
