Protecting Pairing algorithms against physical attacks
Pairing Based Cryptography (PBC) has recently been studied and developed to satisfy emerging industrial and societal needs such as user privacy, identity based encryption or efficient key establishment protocols. Research on PBC has mainly been focusing on the mathematical robustness of the proposed algorithms or on the latter's calculation times. Latest published results have shown that PBC is also vulnerable to physical attacks: research work carried by the Secure Architectures & Systems (SAS) lab of the CEA has shown that all the parts of a Pairing algorithm can be attacked using fault injections. The first objective of this thesis is to study, in the same way as the work done using fault attacks, the vulnerability of PBC to side channel analysis. Then efficient countermeasures shall be studied and tested in order to make PBC implementations immune against physical attacks (fault injections and side channel analysis).
