Abstract
A system, method and elliptic curve cryptography scheme having a fault injection attack resistant protocol. The cryptographic scheme has a first arithmetic operation having at least one of a single input bit, a single output bit, or a single output bit-string that is vulnerable to a fault injection attack. The protocol includes: performing a first arithmetic operation to determine a first output; performing a second arithmetic operation to determine a second output, the second arithmetic operation being a variant of the first arithmetic operation; and comparing the first output and the second output, and if the comparison is incompatible, outputting an invalidity condition, otherwise, outputting the first output.
