    摘要: Techniques for adapting a wireless communication device or system to support a desired functionality of the wireless communication system at an optimized performance and economic benefit are discussed. The desired functionality can be determined by defined criteria such as a maximum range of communication with the wireless communication system, quality of a transmission link in the wireless communication system, capacity of the wireless communication system, power consumption of the wireless communication system, protocols supported in the wireless communication system, modulation techniques used in the wireless communication system and processing techniques for combining signals in the wireless communication system. The system can be adapted by varying one or more of modules (e.g., components or processing techniques) used in the wireless communication system.

    摘要: The present invention relates to a system and method for providing security in an RFID system and provides a secure active RFID architecture that uses a combination of passive and active RFID circuitry and employs authentication and encryption techniques in the processing of data, at rest and over the air. In the method of communicating securely in an RFID system of the present invention, a random number is generated with the passive RFID circuitry. The random number is forwarded to a reader. The reader is authenticated by comparing a first hash value determined from a hash function of the random number generated at the RFID tag and an Authenticated Facility Group ID stored on the RFID tag with a second hash value determined from the hash function of the forwarded random number and an Authenticated Facility Group ID stored in the reader such that if the first hash value matches the second hash value the reader is authenticated. After the reader is authenticated, the tag ID stored at the RFID tag can be revealed. After authentication of the reader, a second layer of security using encryption is provided with the active RFID circuitry.
