摘要： An electronic commerce system facilitates secure electronic commerce transactions among multiple participants. Each electronic commerce transaction involves at least one commerce document defining the transaction and at least one commerce instrument defining a payment for the transaction. The electronic commerce system has a credential binding server at a trusted credential authority, multiple computing units at associated participants, and a communication system interconnecting the credential binding server and the multiple computing units. The electronic commerce system operates in two phases: a registration phase and a transaction phase. During the registration phase, each of the computing units generate and send a registration packet over the communication system to the credential binding server. Unique credentials are produced by the credential binding server based upon the registration packets sent back to the computing units. During the transaction phase, an originating computing unit initially requests, receives, and verifies the credentials of expected recipient computing units to ensure communication between authenticate participants. Thereafter, the originating computing unit signs and encrypts the commerce document(s) and the commerce instrument(s) in a manner which ensures that only the intended recipients can decrypt them. The originating computing unit then sends both the commerce document(s) and instrument(s) over the communication system to a first recipient computing unit. The first recipient computing unit decrypts and verifies the commerce document (s) and/or instruments intended for it. The first recipient computing unit then passes the balance of the encrypted commerce document(s) and/or instrument(s) over the communication system to a second recipient computing unit, which decrypts and verifies the commerce document(s) and/or instrument(s) intended for it. This process is continued until all commerce documents and commerce instruments are distributed, decrypted, and verified by their intended recipients.

摘要： Small application programs called “applets” are defined by pseudo-code (p-code) instructions. Each applet is divided into software components that are executed by a processor, operating as a state machine. The applets are originally written in a high level programming language and then converted into the p-code, for downloading into a non-volatile read/write memory of a portable combination pager and personal information manager (PIM) device that includes the processor. In this device only 1-2 Kbytes of static random access memory (RAM) are available to load the p-code of applets for execution by the processor. The software components include variables and event handlers that respond to events such as key presses of buttons disposed on a control panel of the device. The variables include persistent variables that are stored in memory between invocations of an applet, invocation variables that are store in RAM during execution of an applet, and state variables that are only stored in RAM during a specific state of the applet. Event variables are available for processing of a specific event, but are replaced by different event variables when a different event must be processed. A kernel comprising a portion of the operating system for the device serves as a p-code interpreter, producing machine instructions from the p-code loaded into RAM, for execution by the processor. Accordingly, applets, which comprise only a few kilobytes of p-code, are executed by loading only a few of the software components into RAM at a time.

摘要： A user interface for a combination pager and personal information management (PIM) data device provides considerable versatility in accessing the data and in controlling how the data are displayed to the user. The user interface includes a display screen having only a few rows oil which lines of data are displayed, and four control buttons, including an Up button, a Down button, an Action button, and a Back button. Since the device maintains data in a hierarchical directory structure and starts at the highest (root) level, the Action button is used to move to a lower level in the directory hierarchy, while the Back button is used to move back up to a higher level. In addition, the Action button is employed to initiate a selected function. If a line (or entry) of a list is above the top line displayed on the screen, an upwardly pointing arrowhead is displayed to the user adjacent the top line. Similarly, a downwardly pointing arrowhead is displayed if a line in the list is below the last line on the screen currently displayed. The user can select an application to execute in the root node of the hierarchy when the device is initially turned on, reset, or after a predefined time interval has elapsed. In addition, the user can selectively actuate a faster scroll rate to move up or down through a list that is relatively long. The format applied to data presented to the user in the display screen is user selectable.
