Abstract

An encryption key transfer system, the system may be operative to generate encrypted files on a portable storage medium which may be used to transfer encrypted keys between ATMs using a single operator. Such secret encrypted keys may include a terminal master key. The system may include a source ATM and a target ATM with a common software program and/or hardware installed in each ATM. The source ATM may use secret information associated with the common software program and/or hardware and other randomly generated information to securely encrypt the secret encryption keys. The source ATM may further store the encrypted secret encryption keys and the randomly generated information on a portable storage medium. The target ATM may be operative to decrypt the secret encrypted keys using the secret information associated with the common software program and/or hardware and the randomly generated information retrieved from the portable storage medium.

Dependent claims

A method comprising:

a) providing with a source ATM at least one table of data;
b) generating with the source ATM a hard key responsive to the at least one table of data;
c) generating with the source ATM a data file that includes random information;
d) generating with the source ATM a factory key responsive to the at least one table of data and responsive to at least one first portion of the random information;
e) encrypting with the source ATM at least one secret encryption key responsive to the factory key;
f) including the encrypted at least one secret encryption key in the data file;
g) encrypting with the source ATM the data file using the hard key;
and
h) storing the encrypted data file on at least one portable storage medium in operative connection with the source ATM.

A method comprising:

a) providing with a target ATM at least one table of data;
b) generating with the target ATM a hard key responsive to the at least one table of data;
c) accessing with the target ATM a data file from at least one portable storage medium;
d) decrypting with the target ATM the data file using the hard key;
e) accessing with the target ATM at least one seed key data from the decrypted data file;
f) accessing with the target ATM at least one encrypted secret encryption key from the decrypted data file;
g) generating with the target ATM a factory key responsive to the at least one table of data and responsive to the at least one seed key data;
h) decrypting with the target ATM the at least one encrypted secret encryption key responsive to the factory key to produce the at least one secret encryption key.
