Claims14
A system for securing information for distribution and distributing information to verification equipment, said system comprising:
- means for printing, encrypted information on a medium, wherein the means for printing is
- a computer that generates a key distribution certificate by creating a master distribution public key pair and a session distribution key pair
- an encryptor/decryptor coupled to said computer, said encryptor/decryptor encrypts the session distribution public key with the master distribution private key and encrypts the distribution with the session distribution private key;
- means coupled to said encryptor/decryptor for producing symbols that represent the information encrypted by said encryptor/decryptor;
- mailing the secured information to the owners of verification equipment;
- and
- means for scanning the secured information into the verification equipment to update an information key file.
A method for producing decryption keys and distributing decryption keys to encryption equipment, said method comprising the steps of:
- printing decryption keys in a secure manner on a medium by generating a key distribution certificate by creating a master distribution public key pair and a session distribution key pair;
- encrypting the session distribution public key with the master distribution private key and encrypting the distribution with the session distribution private key:
- producing symbols that represent the information encrypted;
- mailing the decryption keys to the owners of encryption equipment;
- and
- scanning the decryption key into the encryption equipment to update a decryption key file.
