摘要： A message is signed using a PUF without having to exactly regenerate a cryptographic key. Another party that shares information about the PUF is able to verify the signature to a high degree of accuracy (i.e., high probability of rejection of a forged signature and a low probably of false rejection of a true signature). In some examples, the information shared by a recipient of a message signature includes a parametric model of operational characteristics of the PUF used to form the signature.

摘要： A method for coordinating reader transmissions according to one embodiment includes, at a first reader, receiving from a second reader a request to transmit to a radio frequency identification tag; and if the first reader is transmitting, sending a denial of the request from the first reader to the second reader. A method for coordinating reader transmissions according to another embodiment includes from a first reader, sending to a plurality of readers a request to transmit to a radio frequency identification tag; waiting for responses from the plurality of readers; if a denial of the request is received by the first reader from any of the readers, not transmitting to the radio frequency identification tag; and if no denial of the request is received by the first reader from any of the readers, transmitting to the radio frequency identification tag. Additional systems, methods and computer program products are presented.
摘要翻译：根据一个实施例的用于协调读取器传输的方法包括在第一读取器处从第二读取器接收要发送到射频识别标签的请求; 并且如果第一读取器正在发送，则将拒绝该请求从第一读取器发送到第二读取器。根据另一实施例的用于协调读取器传输的方法包括从第一读取器向多个读取器发送发送到射频识别标签的请求; 等待多位读者的回应; 如果第一读取器从任何读取器接收到拒绝请求，则不发送到射频识别标签; 并且如果第一读取器不从任何读取器接收到请求的拒绝，则发送到射频识别标签。介绍了其他系统，方法和计算机程序产品。

摘要： Systems and methods for activating one or more devices are disclosed. The device listens for an activate code (300, 306), the activate code having a length field (322) and a mask field (326) , the mask field including a mask value, the length field specifying a length of the mask field to a final bit of the mask value. Upon receiving the activate code, the length field is compared to a stored length value for determining whether the length field meets a predefined criterion. If the length field meets the predefined criterion, an address of the activate value is loaded (if an address field is present) and the appropriate bits (mask value) of the mask field are compared to a stored activate value. An activate signal is generated if the mask value matches the stored activate value . The activate signal' can be used to activate additional circuitry including the entire device .

摘要： A system according to one embodiment of the present invention includes a first clock signal generator generating a first clock signal at a first frequency, and a second clock signal generator generating a second clock signal at a second frequency that is higher than the first frequency. The first clock signal is used to calibrate the second clock signal generator. An RFID device according to another embodiment of the present invention includes a crystal controlled first clock signal generator generating a first clock signal at a first frequency, a second clock signal generator generating a second clock signal at a second frequency that is higher than the first frequency, and an activate circuit. The second clock signal generator is inactive until activated by the activate circuit. The first clock signal is used to calibrate the second clock signal generator. Methods are also presented.
