Abstract:
A method for using cryptographic parameters in a postage meter for securing postage indicium data, the method comprising the steps of:generating in the postage meter 1) first cryptographic parameters which are useable in conjunction with second cryptographic parameters by the postage meter to cryptographically secure postage indicium data and 2) a cryptographic key; storing the first cryptographic parameters but not the second cryptographic parameters in the postage meter during the registering of the cryptographic key with a certificate authority; receiving at the postage meter notification that the cryptographic key has been registered with the certificate authority; subsequent to receiving the notification generating and storing the second cryptographic parameters in the postage meter such that the first and second cryptographic parameters are stored in the postage meter for use in cryptographically securing postage indicium data.
