摘要:
A method of issuing digital tokens in a open system meter comprising the steps of: sending a request for digital tokens and predetermined postal information, including addressee information, from a host processor to a vault that is operatively coupled to the host processor; calculating in the vault in response to the request for tokens at least one digital token using the predetermined postal information; debiting postal funds in the vault; issuing the digital token to the host processor; and storing the digital token and the predetermined postal information as a transaction record in the host processor for subsequent generation and printing of an indicia.

A system and method include means for processing a cryptographic certificate adapted to provide security functionality. A register means (244) is provided and means (224) for adjusting the register means to account for services when the cryptographic certificate is processed. The register means may be for storing funds. Means are provided for processing a digital token providing proof of postage payment and means are also provided for processing a cryptographic certificate adapted to provide security functionality. Funds stored in the register means are debited when the digital token is processed and when the cryptographic certificate is processed. Processing the cryptographic certificate may involve many functions such as providing security services and/or certificate management functions (including generating and verifying cryptographic certificates) and/or key management functions and/or access to any needed private keys to perform security services. Processing the digital token may include generating the digital token or issuing the digital token.

A super password is a one time use password that is issued to a user for the singular purpose of reinitializing the user password system for a meter. When the meter is manufactured, the meter and the Data Center share secret data such that they can execute a predefined and identical algorithm for secure communication. Through such secure communications, the Data Center can authenticate a metering system, and the metering system can accept a predefined command from the Data Center securely. Counters are used as data to encypt. One counter is used for the one way communication from the meter to the data center and counts the number of times that the meter issues a one time authentication code. Another counter is used for the one way communication from the Data Center to the meter and counts the number of times that the Data Center issues a one time super password. The counters are used for two purposes: as data to be encrypted and to confirm the delivery of secure codes between the Data Center and the meter. The use of counters in the process eliminates problems that undelivered messages would create.

摘要:
A cost-effective motion control system communication architecture is provided that supports a centralized control node, distributed control nodes, and smart I/O peripheral control nodes. Networks designed using this architecture, which employs a serial bus, may be readily modified or expanded. The architecture supports both real-time highly periodic communications and event-driven peer-to-peer communications.

A communication network is comprised of a first, second, third and fourth controller node in line communication. Each controller node includes a microprocessor. Each microprocessor is programmable to respond to and generate data message bytes, each data byte having one start bit, eight data bits, one programmably settable bit and one stop bit. Each microprocessor is further programmable to respond only to a unique address-command data message byte from a message source node. The address-command byte is recognized because the settable bit is set. Each microprocessor is programmed to generate a reply message byte with the ninth bit not set and to then receive from the source node a message count byte followed uninterrupted by the data message bytes. Upon receiving a complete data message conforming to the received count of the count byte, the microprocessor then generates an acknowledgement byte.
