  *          1 test vector is extracted to demonstrate PKA capability to
  *          verify a signature using ECDSA (Elliptic Curve Digital Signature Algorithm) 
  *          signature verification function principle.
  *          It is adapted from SigVer.rsp section [P-256,SHA-256] available under
  *          http://csrc.nist.gov/groups/STM/cavp/documents/dss/186-3ecdsatestvectors.zip
  *          and provided in the same directory for reference.
