2004: UHF Gen2 Ratified
• Two readers using DRM
– Transmitting simultaneously
– Inventorying simultaneously
• Tags moving fast
• Readers rejecting interference
• No missed tags or ghost reads

2005: Walmart Pallet Tests Proved Gen2
• Speedway™ prototype on either
side of dock door
• AD-620 (Triflex™) tags on each
of 40 boxes of Caress® soap
• Multiple interfering readers
transmitting simultaneously

4. © 20104 | © 2013
2006: Impinj Introduces Near-Field UHF
• UHF Gen2 works both near & far, on all types of items
– Allows a single infrastructure for pallets, cases, and items
– The only frequency with this property
• Far field: 30cm to 15m range
• Near field: 0 to 60cm range
– Reads on liquids and metals
– The only difference is the antennas

2007: UHF Gen2 Beat HF for Pharma
• UHF outperformed HF at NACDS
• UHF reliably wrote & read bottles at
2× speed of fastest pharma line
• Impinj deploys UHF Gen2 on Purdue
Pharma production line

6. © 20106 | © 2013
2008: Gen2 Enhanced for Item Tagging
• New Gen2 V1.2.0 adds UM indicator, XPC, BPL, and
recommissioning specifically for item tagging
• Impinj develops item
solution for Metro
Galeria Kaufhof
– 30,000 tagged items
on the sales floor

7. © 20107 | © 2013
2009: Enabled Myriad Products
• Hand-Held Readers
• Fixed Readers
• Cards & Modules

The Situation Today
• Retail is adopting UHF RFID broadly
– American Apparel, Macy’s, Memove, Liverpool, Zara, JCP,
Walmart, Marks & Spencer, Kohl’s, more
• Other UHF RFID applications are growing
– Embedded RFID, asset tracking, laundry, border crossing,
customer experience, manufacturing, more
• Do we have the technology we need?

Gen2 Today Definition
Select Select a population of tags
Inventory Inventory selected tags; get their EPCs
Access Read/write/lock tag memory; kill the tag
New in UHF Gen2 V2 (aka G2) protocol
In today’s UHF Gen2 protocol
G2 Enhancements Definition
Anticounterfeiting Authenticate a tag as genuine
Security Modify tag information securely
File Management Create files and assign access privileges
Untraceability Hide tag data to protect consumer privacy
Loss Prevention Use a tag for EAS
Authenticating an Item: UHF Gen2 V2.0.0

18. © 201018 | © 2013
G2 for Cryptographic Authentication
• Reader reads static TID from
tag memory
• Counterfeiter can clone tag
by copying TID
Today’s Gen2 RFID Future G2 RFID
Read
TID
Challenge (RN)
Response
• Tag computes response from
reader’s random challenge
and tag’s secret key
• Counterfeiter cannot clone tag
without knowing secret key
TID Key

19. © 201019 | © 2013
G2 for Cryptographic Security
Command Function
Challenge Challenges multiple tags simultaneously
Authenticate Performs tag, reader, or mutual authentication
AuthComm Authenticates a tag message with a MAC
SecureComm Encrypts a tag message
KeyUpdate Updates a tag’s stored key
FilePrivilege Alters a reader’s privileges to a file
TagPrivilege Alters a reader’s privileges to the tag

20. © 201020 | © 2013
G2 for File Management
Tag Memory
Key Concept: Partition User Memory into Files
Readers have per-file read,
write, and lock privileges
G2 supports up to 1023 files,
each of which can be up to
~2 Mbytes in size

21. © 201021 | © 2013
G2 for Consumer Privacy (Untraceability)
Hide none or all
Hide none, unique serialization, or all
Hide none, part , or all
Hide none, part , or all
Tag Memory
Protected by range reduction,
access privileges, or both
Key Concept: Hide Portions of Tag Memory

G2 for Loss Prevention

23. © 201023 | © 2013
G2 Status
• GS1 EPCglobal has finished the protocol
– Has passed community review
– In final stages of IP review
– BoG ratification in 2013
• ISO is standardizing the crypto suites
– 9 crypto suites submitted to date
• Present, ECC, AES(×2), Grain, CryptoGPS, XOR, ECDSA-ECDH
– ISO will ratify the first crypto suites in 2014
