On Countermeasures Against Fault Attacks on Elliptic Curve Cryptography Using Fault Detection

Abstract

In this chapter, we study fault detection in finite field and elliptic curve arithmetic operations as a countermeasure against fault attacks in elliptic curve cryptography. In this regard, we review parity-based and time redundancy-based approaches described in the literature for finite field operations. For elliptic curve cryptography, we also present some approaches based on input randomization and point validation.
