阅读说明：本技术 具有预定信息层的磁性puf (Magnetic PUF with a predetermined information layer ) 是由 凯斯·布莱恩·哈丁 于 2020-03-21 设计创作，主要内容包括：本发明将物理信息层(“PIL”)添加到在基质内的磁性颗粒,创建了不可克隆功能“对象”。PIL有助于利用包括搜索索引的附加信息搜索找到与预定的被登记组合匹配的组合,该搜索索引限制搜索以便在登记数据库中找到匹配所需的数据的范围。该索引可以是将随机磁剖面值关联到数据库中的被登记值的列表的预定值。附加信息可以包括需要容易被传递给PUF用户的产品信息或一般信息。(The present invention adds a physical information layer ("PIL") to the magnetic particles within the matrix, creating an unclonable function "object". PIL facilitates searching for combinations that match a predetermined registered combination using additional information including a search index that limits the scope of the data that is needed to search to find a match in the registration database. The index may be a predetermined value that relates the random magnetic profile value to a list of registered values in a database. The additional information may comprise product information or general information that needs to be easily communicated to the PUF user.)
