RFID AUTHENTICATION

ABSTRACT:

RADIO Frequency Identification (RFID) tags for the function of next-generation electronic product code (EPC) will become one of the most widely used devices in the near future an RFID. Once the tag is found valid, the back-end database will look up its product information for further processing. RFID tags are classified into three types: active, semi passive, and passive. Active tags contain batteries so that they can actively communicate with the reader. Semi passive tags also contain batteries but they wait for the readers query. As for passive tags, the power comes from the reader. The class of a tag represents the effective reading range. We analyzed the number of rounds required and the period of key update for practical deployment.

EXISTING SYSTEM:

Radio Frequency Identification (RFID) systems are a common and useful tool in manufacturing, supply chain management and retail inventory control. Optical barcodes, another common automatic identification system, have been a familiar packaging feature on consumer items for years. Due to advances in silicon manufacturing technology, RFID costs have dropped significantly. In the near future, low-cost RFID electronic product codes or smart-labels may be a practical replacement for optical barcodes on consumer items. Unfortunately, the universal deployment of RFID devices in consumer items may expose new security and privacy risks not present in closed manufacturing environments. This presents an introduction to RFID technology, identifies several potential threats to security and privacy, and offers several practical proposals for efficient security mechanisms. We offer several policy suggestions and discuss various open questions and areas of research.

PROPOSED SYSTEM:

In this project, we propose a novel authentication protocol based on Gen2, called Gen2+, for low-cost RFID tags. Our protocol follows every message flow in Gen2 to provide backward compatibility. Gen2+ is a multiple round protocol using shared pseudonyms and Cyclic Redundancy Check to achieve reader-to-tag authentication. Conversely, Gen2+ uses the memory read command defined in Gen2 to achieve tag-to-reader authentication. We show that Gen2+ is more secure under tracing and cloning attacks.

Module Description:1. Tag reader authentication module.An RFID reader is a device that is used to interrogate an RFID tag. The reader has an antenna that emits radio waves; the tag responds by sending back its data.

A number of factors can affect the distance at which a tag can be read (the read range). The frequency used for identification, the antenna gain, the orientation and polarization of the reader antenna and the transponder antenna, as well as the placement of the tag on the object to be identified will all have an impact on the RFID systems read range.

2. Crypt analysis module.Lightweight authentication protocol based on Gen2 to resist various attacks. The proposed tag uses no cryptographic function, and hence, is suitable for low-cost RFIDs. Without changing the protocol flow of Gen2, the existing reader can read both Gen2 tags and Gen2+| tags. Gen2+ provides sufficient security level for real-world settings. We analyzed the number of rounds required and the period of key update for practical deployment.

3. DB verification Module.Database used there first to reenroll the clients information and after its verified by admin after that is stored in server for future request for tag readers.

4. Private and Public mode module.Private mode and switched back whenever they want. Under such a scenario, our scheme provides flexibility between the private mode and the public mode. For those items, which need to be invisible from the outside world? users switch them into the private mode by setting the threshold value t to 0. Then, the tag can avoid tracing and skimming attacks. They can pass through attackers effective reading range in a public domain. In addition, these tags in their private mode react to the malicious reader one after another by sending nonsense just like passive-jamming tags. As for the public mode, we set t to a higher value. Then, the reading speed increases rapidly. However, this also exposes the tag to the environment. This is configurable according to users preference.
