While PKI legislation has acquired significant momentum it is not clear that lawmakers have carefully considered the public policy implications and long-term consequences of these laws. 1. Is legislation necessary at all Proponents of digital signature legislation start with the premise that the need for a PKI is clear public key cryptography and verifiable certificates offer the best hope for sending secure authentic electronic messages over open networks thereby facilitating electronic commerce. They argue that the reason that the commercial marketplace has not produced a viable certification authority CA industry is because of legal uncertainty CAs are unable to determine their potential liability exposure because of a confusing array of applicable background law or because existing law imposes too much liability on CAs. Thus proponents argue legislation is necessary in order to provide certainty in the marketplace and allow a much-needed industry to emerge as well as to address other issues such as the legal status of digitally signed documents. Opponents of this view assert that it is far too soon to conclude that the market will not produce commercial CAs and point to the increasing numbers of commercial CAs emerging even in the absence of legislation. Time is solving the uncertainty problem opponents argue and the too much liability problem is the product of flawed business models not a flawed legal system. Opponents of legislation argue that the real danger is that a group of lawyers will impose a set of flawed rules that will fundamentally skew a dynamic infant marketplace .
