Balanced point operations for side-channel protection of elliptic curve cryptography

  title={Balanced point operations for side-channel protection of elliptic curve cryptography},
  author={Lejla Batina and Nele Mentens and Bart Preneel and Ingrid Verbauwhede},
The authors propose balanced algorithms for elliptic curve cryptography (ECC). The authors make the point addition and doubling balanced; that is, they are implemented as identical sequences of operations. As an example the authors implement an ECC point multiplication algorithm, using the approach of Montgomery, for which a single power trace does not expose the Hamming weight nor the bits of the secret key. Nevertheless, their fieldprogrammable gate array implementation is also compact and… CONTINUE READING
