    摘要： A Key Management System for generating, distributing and managing cryptographic keys used by an information transaction system that employs cryptographic means to produce evidence of information integrity. The system comprises a plurality of functionally distinct secure boxes operatively coupled to each other. Each of the secure boxes performs functions for key generation, key installation, key verification or validation of tokens. Computers, operatively coupled to the secure boxes, provide system control and facilitate communication among the secure boxes. A plurality of separate logical security domains provide domain processes for key generation, key installation, key verification and validation of tokens produced by the transaction evidencing device within the domain using the key management functions. A plurality of domain archives, corresponding respectively to each of the security domains, securely and reliably record key status records and master keys for each domain. The Key Management System installs the master keys in the transaction evidencing device and validates the tokens. The secure boxes include a key generation box for generating, encrypting and signing a master key; a key installation box for receiving, verifying and decrypting the signed master key and for installing the master key into the transaction evidencing device; a key verification box for verifying the installation of the master key in the transaction evidencing device, a token verification box for verifying the tokens, and at least one manufacturing box for generating domain keys and distributing the domain keys among the secure boxes for each of the domains.

    摘要： A transaction evidencing system includes a plurality of computer systems operatively configured to form a network with one of the computer systems functioning as a server and the remaining computer systems functioning as clients. Each of the computer systems includes a processor, memory and storage media. At least some of the storage means includes non-metering application programs that are selectively run on the client computer systems. An unsecured printer is operatively coupled to at least one of the computer systems for printing in accordance with the non-metering application programs. A portable vault card, which is removably coupled to the server computer system, includes digital token generation and transaction accounting processing. The client computer systems issue requests for digital tokens to the server computer system in response to requests for indicia from the non-metering application programs. The requests for digital tokens include predetermined information required by the token generation processing. The server computer system communicates with the vault card when the vault card is coupled to the server computer system, sending the requests for digital tokens to the vault card and receiving from the vault card the generated digital tokens. The server computer system sends each digital token to the client computer system that requested the digital token. The requesting client computer system generates an indicia bitmap from the digital token. The server computer system receives from the vault a transaction record that includes the digital token and the predetermined information and stores the transaction record in its storage media.

    摘要： A method for controlling keys used in the verification of encoded information generated by a transaction evidencing device and printed on a document comprises the steps of generating a plurality of random verifier master keys to obtain a set of verifier master keys consisting of a fixed number of keys; generating at least one pointer by applying a psuedorandom algorithm to data unique to the transaction evidencing device; calculating a plurality of verifier token keys to obtain a verifier token key set corresponding to the set of verifier master keys; encrypting the verifier token key set with a privacy key; and distributing the set verifier token keys and the privacy key to verifiers. The token keys are a function of the verifier master keys and a code valid for a limited time. The pointer algorithm is an appropriate symmetric key cryptographic algorithm and the code is function of a date dependent parameter. The master keys are distributed to postal and vendor data centers.
