Improved Side Channel Attacks on Pairing Based Cryptography
Techniques from Pairing Based Cryptography (PBC) are used in an increasing number of cryptographic schemes. With progress regarding efficient implementations, pairings also become interesting for applications on smart cards. With these applications the question of the vulnerability to Side Channel Attacks (SCAs) arises. Several known invasive and noninvasive attacks against pairing algorithms only work if the second but not if the first argument of the pairing is the secret. In this paper, the authors extend some of these attacks also to the case where the first argument is the secret.
