  • Person A is given nonce “A”
  • Person B is given nonce “B”
  • Person B attempts to submit data to the server on behalf of person A
  • The server reads the submitted data from person B as “Person A with nonce ‘B’ is submitting data”. Knowing that Person A does not have nonce ‘B’, it ignores/denies the submitted data.
