technology neutrality on electronic signatures
... If a cryptosystem is made to work, then we enter into the boundaries of science and technology so, at this point, technology neutrality should be applied. The first statement that technology neutrality can make is to declare neutrality on asymmetric cryptosystems. So technology neutrality should pre ...
