Abstract
Abstract A method of manufacturing transaction evidencing devices, such as digital postage meters, includes the steps of generating a master key in a logical security domain of a Key Management System (10); installing the master key into a digital postage meter (36); verifying the installation of the master key; and registering the master key to a logical security sub-domain in the Key Management System. The step of generating the master key further includes the steps of generating a domain; generating at least one sub-domain; installing the domain in secure boxes of the Key Management System; generating a master key and test token within the domain; and recording the master key in the domain archive. The step of installing the master key further includes the steps of installing the master key into a digital meter (36);and associating the master key with a unique device identifier. The step of registering the master key to a logical security sub-domain in the Key Management System (10) further includes the steps of assigning a sub-domain to the digital meter; installing a postal identifier into the digital meter; associating the postal identifier to the unique device identifier; generating a registration token in the digital meter based on the postal identifier and the unique device identifier; generating registration tokens using the master key recorded in the archives (25); verifying that the registration tokens are identical; and recording the master key in the sub-domain. The steps are repeated for each domain assigned to the digital postage meter.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
60 words
A method of manufacturing transaction evidencing devices comprising the steps of: a) generating a master key in a logical security domain of a Key Management System; b) installing the master key into a transaction evidencing device; c) verifying the installation of the master key; and d) registering the master key to a logical security sub-domain in the Key Management System.
Claim 2
Dependent Claim
56 words
The method of claim 1 wherein said step of generating the master key further comprises the steps of: generating a domain; generating at least one sub-domain; installing the domain in secure boxes of the Key Management System; generating a master key and test token within the domain; and recording the master key in the domain archive.
Claim 3
Dependent Claim
29 words
The method of claim 1 or 2 wherein said step of installing the master key further comprises the step of: associating the master key with a physical device identifier.
Claim 4
Independent Claim
67 words
The method of any preceding claim wherein said step of verifying the master key further comprises the steps of: generating a token in the transaction evidencing device; verifying that the test token and the transaction evidencing device generated token are identical; generating a token from a master key in the archive; and verifying that the transaction evidencing device generated token and the archive generated token are identical.
Claim 5
Independent Claim
103 words
The method of any preceding claim wherein said step of registering the master key to a logical security sub-domain in the Key Management System further comprises the steps of: assigning a sub-domain to the transaction evidencing device; installing a logical device identifier into the transaction evidencing device; associating the logical device identifier to the physical device identifier; generating a registration token in the transaction evidencing device based on the logical device identifier and the physical device identifier; generating registration tokens using the master key recorded in the archives; verifying that the registration tokens are identical; and recording the master key in the sub-domain.
