What is UHF RFID tags?

UHF RFID is an acronym mouthful. UHF stands for ultrahigh frequency, while RFID stands for radio frequency identification. In some instances, this technology is replacing barcodes as a method of managing warehouse inventory and the supply chain. RFID tags are placed on each object and UHF radio frequencies read the stored data. A UHF RFID tag allows stock to be managed and tracked without an employee manually scanning each item.

UHF is a large radio band that ranges from 300 MHz to 3 GHz. Cell phones, pagers and satellite communications use this band, because it can be broken up into numerous sub-bands. The distance the tag is able to transmit depends on the UHF sub-band used, with lower frequencies having shorter ranges. The UHF RFID tag may use sub-bands that provide a range as small as 6 feet (1.8 meters).

UHF RFID requires three components: a transponder, an antenna and a transceiver. The transponder, or tag, contains data and is attached to the item. The antenna transmits the UHF radio signal to the transponder, powering and activating it. The activated transponder then transmits the data stored on the tag back to the transceiver. Data such as who is in possession of an item, where the item is during shipment and the location of an item in a warehouse can all be read from the RFID tag.

The UHF RFID tag has numerous benefits over the more common barcode. The tag can hold much more data and, unlike a barcode, data can be added, updated or changed. While a barcoded item needs to be oriented so the barcode faces outward, the RFID tag does not have to be visible. Printed barcodes are also susceptible to wearing or weathering during shipment. A UHF RFID tag can be placed inside the packaging for protection.

There are two types of UHF RFID tags, active and passive. Active RFIDs have a battery, allowing them to be self-powered and store a large amount of data. Governments use these active tags to audit shipments because they cannot be erased. Passive RFIDs are the most widely used and the typical tag can store between 8 kilobytes (kB) and 32 kB of data. Passive tags can be erased, allowing data to be rewritten and the tag reused.

One drawback is that UHF RFID tags rely on radio waves, and some material can cause radio interference. Factories with steel frameworks, metallic products or liquids may be a challenge for RFID. Barcodes may be a more reliable option for managing these types of products in the supply chain.

Security and privacy may also be an issue with the UHF RFID tag. The information on the tags is generally not encrypted and the radio waves are easily received. It may be possible for a hacker to collect information from tags simply by standing near a loading dock. Private information such as a customer’s name or special pricing can be picked up and exploited.

Security in a UHF RFID tag

In the UHF tags available today there really is no security, in fact in many of the RFID tags that are used in applications today, there is no security. It is not needed, and so there has been no attempts to include it.

The one area that this not true is in the area of financial transactions where the predominant standard is ISO/IEC 14443. This standard (the basis of NFC, Near Field Communications) is a High Frequency (13.56 MHz) standard that includes the capability for encryption of the information on a tag. This capability does not exist for UHF tags – at the moment.

There have been many meetings of the UHF RFID experts to talk about how to add true security to a UHF RFID system.

This majority of RFID applications do not need security. The unique number stored in the tag means nothing to someone reading the tag unless they have access to the databases that explain the meaning of the number. However, some applications want to have more information stored in the tag and some of that information may be sensitive. Hence the need for security.

There are several areas that require the use of security. These include untraceability, loss-identification and/or protection, memory-locking, and privilege-management. To allow some of these to be implemented we also need to add file-management capability.

In order to achieve security, the tag and the reader have to prove to each other that they are allowed to talk. This is called authentication and it is a necessary process before the tag tells the reader any information. This is the first stage of the secure process.

There are several parts to the Authentication process. The tag must declare and prove that it is capable of secure communications. The interrogator must declare that not only is it capable but that it is allowed to access certain information on the tag. There may be information on the tag that not all interrogators are allowed to access, and so there must be a method of creating privilege based access and hence file areas on the tag.

Once the tag and interrogator have authenticated each other, then the secure communication can start. By secure communication we mean the “real-time” encryption of the data that passes between the tag and interrogator. This is not the storing of encrypted data, it is the process where the tag has the ability to encrypt anything it communicates to an interrogator.

The implications of having an encryption engine on board a passive tag are obviously very wide. The loss of power to the tag during the encryption process means that the data does not get secured and transmitted, so a lot of work has to go into the design of these new tags.

One of the areas that the experts have been looking at is what encryption routines should be available. The group has decided that there should be no restrictions as some applications may only require very simple security while others may need the power of an AES type encryption. the idea is to not include the encryption algorithm informatuon in the air interface standard but to create another document where all the algorithms are detailed. The manufacturer of the tags would then be able to decide which encryption suite his tags will support.

In ISO, the air interface for UHF type C (ISO/IEC 18000-63) will be the first standard to be created for a secure RFID system. The basis for the security is already included in ISO/IEC 29167-1 which is currently in ballot. The specific information for each type of tag is then included in the air interface standards (ISO/IEC 18000 series). The standard that will specify the security suites has not yet been decided, but there is a proposal that ISO/IEC 29167 be the home for these suites.

Not all tags will require security, and the extra cost for the tags will not be something that all applications can bear so these specifications will all be optional.

The work has begun to create the standards for this concept, but it will not be complete for a while. In fact we will probably not see the standards published until late in 2012. As the work progresses, I will update the blog with information.
