Abstract
Currently used inexpensive IC cards (e.g. payphone cards) prove their authenticity and generate digital signatures by means of a simple circuit which implements a nonlinear one-way transformation. The paper considers possible approaches for the efficient design and fabrication of such a circuit, based on the observation that the circuit does not have to serve any predefined exact process as long as its functioning falls within a wide range of possible allowed behaviours. It is shown how this tolerance in defining the circuit's behaviour can potentially be traded for efficient design and fabrication of the circuit, without necessarily sacrificing security.
