摘要： System and method for tracking inventory of a multiplicity of products. First RFID tags are associated with respective products or groups of products. Second Active RFID tags are associated with respective first containers for the multiplicity products. A third Active RFID tag is associated with a second container for the first containers. First RFID tags broadcast their respective identifications. Second Active RFID tags hash the identities of the first RFID tags within their respective first containers and broad their hashed values. Third Active RFID tag hash the hashed values broadcast by the second Active RFID tags. An expected value is compared to a result of the third Active RFID tag hashing the hashed values broadcast by the second Active RFID tags.

摘要： A remote user, two-way authentication and password change protocol that also allows parties to optionally establish a session key which can be used to protect subsequent communication. In a preferred embodiment, a challenge token is generated and exchanged which is a one-time value that includes a random value that changes from session to session. The construction and use of the challenge token avoids transmission of the password or even the transmission of a digest of the password itself. Thus the challenge token does not reveal any information about a secret password or a digest of the password.

摘要： A method to exchange and authenticate public cryptographic keys between parties that share a common but secret password. The parties exchange public keys, where the public keys are accompanied by hashed values based on the keys, the password, and random numbers. Each party then encrypts its random number using the public key of the other party, and the encryptions are exchanged. Based on the received encryptions and the known password, each party then re-computes the hashed value received from the other party, and compares the re-computed hashed value with the received hashed value. If the two are the same, the public key that accompanied the hashed value is judged authentic.

摘要： Packets or frames of data may be compressed, encrypted/decrypted, filtered, classified, searched or subjected to other deep-packet processing operations before being distributed through the internet. The microprocessor system and method of the present invention provide for the orderly processing of such data packets without disrupting or changing the sequence in which the data is intended to be transmitted to its destination. This is achieved by receiving frames into an input buffer for processing. Associated with this input buffer is a unit for determining the operation to be performed on each frame. An arbitrator assigns each frame to a processing core engine. An output buffer collects the processed frames, and a sequencer forwards the processed frames from the output buffer to their destination in the same order as received by the input/output buffer. Maintaining the sequence of data transmission is particularly useful in voice transmission, such as videos and movies.
摘要翻译： 数据包或数据帧可以在通过因特网分发之前被压缩，加密/解密，过滤，分类，搜索或经受其他深度包处理操作。 本发明的微处理器系统和方法提供这种数据分组的有序处理，而不会中断或改变数据要发送到其目的地的序列。 这通过将帧接收到用于处理的输入缓冲器中来实现。 与该输入缓冲器相关联的是用于确定要在每个帧上执行的操作的单元。 仲裁员将每个帧分配给处理核心引擎。 输出缓冲器收集经处理的帧，并且定序器按照输入/输出缓冲器接收的顺序将处理后的帧从输出缓冲区转发到其目的地。 保持数据传输的顺序在诸如视频和电影的语音传输中特别有用。

摘要： A time stamping protocol has two stages referred to as the ticketing stage and the certification stage. During the ticketing stage, the document or other identifying data is sent to the TSA. The TSA generates a “ticket” based on the document or other identifying data and a time indication derived from a trusted clock. The ticket, which serves as an unsigned time stamp receipt, is transmitted back to the document originator. During the certification stage, the holder of the ticket requests a certified time stamp receipt by presenting the ticket to the TSA. The TSA verifies the ticket and generates a signed time stamp receipt, called the ticket stub, which is then transmitted back to the document originator. The ticket stub serves as a “universal time-stamp” that the holder of the ticket stub can use to prove the date of the document.

摘要： Embodiments of the present invention provide systems, articles of manufacture and methods for a telematic parametric speed metering system. In one embodiment, a system may determine a vehicle's location and speed. Once the location has been determined, corresponding geographical zone based speed limits and/or other information may be acquired via internal memory or data transmission. The speed of the vehicle may then be compared against the speed limits for the zone. If the vehicle's speed exceeds those speed limits, one or more of a plurality of actions may be performed including (but not limited to) warning the driver via a visual or audio signal, informing an authority agency via data transmission, logging the excessive speeding condition (e.g., time, date, speed, location, driver name, etc).

摘要： A time-stamping protocol for time-stamping digital documents uses a time-based signature key. A document or other identifying data is sent to a time stamping authority TSA. The TSA has a time-based signature key that the TSA uses to sign time stamp receipts. The signature key is associated with a fixed time reference that is stored in a public key certificate also containing the public verification key. Upon receiving the document, the TSA creates a time stamp receipt by computing a time difference between the time reference associated with the signature key and the time the document was received. The time difference is appended to the document to create a time stamp receipt and the receipt is then signed by the TSA and transmitted to the requestor.
