1. A method and apparatus for generating public keys and a proof that the keys were generated by a specific algorithm comprising the steps of:

  • the user'"'"'s system generating a random string of bits based on system parameters;

    the user running a key generation algorithm to get a secret key and public key using the random string and public parameters;

    the user constructing a proof being a string of bits whose public availability does not compromise the secret key and wherein said constructing of said proof requires access to said secret key, but at the same time said proof provides confidence to at least one of a plurality of other entities that said public key was generated properly by the specified algorithm, and wherein said confidence is gained without having access to any portion of said secret key.
