I such that the left and right parts of the result match a particular pattern. L.C. Guillou and J.-J. Quisquater. N ffi 403, pp. So, no valid signatures can be generated outside the camera. Furthermore , we also commit the person who handles the camera.
Hash functions are very sensitive to a modification of even one bit.
Hence , we had to take care that the transmission errors would not prevent pieces of editing or J. J . This scheme is ideal for smart card implementations because exchanges with the outside world are timeconsuming and the resources of the card are limited. Imagine that several entities want to sign the same message. We will illustrate the signature process for two entities, but it may easily be extended to any number of entities. 403 of Lecture Notes in Computer Science, Springer-Verlag, pp.
