摘要： In one embodiment of the present invention, a source point, or security management entity, within a supply chain labels a shipment to be shipped through the supply chain with numbers, text strings, or other type of label information. Different label information may be placed at each of multiple levels of packaging as well as on objects within the packaging. The source point devises an encryption-key chain via a one-way function, and encrypts combinations of the label information incorporated within the packaging and objects using encryption keys from the encryption-key chain to produce one or more encrypted label tags. The one or more encrypted label tags are affixed to the shipment by the source point, and the shipment is sent into the supply chain for eventual delivery to a destination point. At pre-selected intervals of time, the source point reveals encryption keys within the encryption-key chain. In one embodiment of the present invention, revealing of encryption keys allows intermediate points or the destination point in the supply chain at which the shipment resides to extract label information and apply the most recently revealed encryption key to compute a label-tag value, and to then compare the computed label-tag value to a label tag affixed to, or incorporated within, the shipment.
摘要翻译：在本发明的一个实施例中，供应链内的源点或安全管理实体通过数字，文本串或其他类型的标签信息来标记要通过供应链运送的货物。不同的标签信息可以放置在包装的多个级别的每一个以及包装内的物体上。源点通过单向函数设计加密密钥链，并使用加密密钥链中的加密密钥加密包装和对象内的标签信息的组合，以产生一个或多个加密标签标签。一个或多个加密的标签标签由源点附加到货物，并且货物被发送到供应链中以最终递送到目的地点。在预选的时间间隔内，源点显示加密密钥链中的加密密钥。在本发明的一个实施例中，加密密钥的揭示允许出货所在的供应链中的中间点或目的地点提取标签信息并应用最近公开的加密密钥来计算标签标签值，并且然后将计算的标签标签值与贴在或合并到货物中的标签标签进行比较。
