ABSTRACT:
This invention discloses an encryption method for generating an encrypted message which is controllably decryptable, the method including providing at least one agency public key to at least one decrypting agency entity respectively and to each of a first plurality of subscriber entities and to each of a second plurality of regulator entities, providing an ID, a public key and a private key for each of the first plurality of subscribers and each of the second plurality of regulators, for each subscriber entity and for each regulator entity, employing at least one agency public key to encrypt the entity's private key, and for each individual subscriber entity and for each individual regulator entity, generating a certificate attesting, for all other entities, to the individual entity's status, ID, public key and encrypted private key.
