Security
Current Activities - Security
 TIA Committee TR-45 supports security standards
development for US TDMA (TIA-136) and CDMA
(TIA-2000 and TIA-856)
 Most of TR-45’s work involves transposition of
specifications developed by 3GPP2 TSG-S WG4
 Current efforts:
• New Revision of Security framework for Femto-cells
• Advanced Security Framework for HRPD, eHRPD and
xHRPD
• Security for cdma2000 1x
3
Current Activities - Security
 Equipment Numbering Identifier security continues
as discussion items during Global Numbering Joint
Expert Meetings moderated by TR-45 EUMAG
hosted by IMEI (GSMA) & MEID (TIA)
Administrators.
 Air-Interface Application Layer Security
Strategic Direction
 TIA expects its TR-45 security work to continue to
be driven by 3GPP2, with input from IETF and
3GPP
 Security for Machine-to-machine communications
will be addressed in 2010-2011
 TR-45 EUMAG Chair moderates IMEI -Global
Decimal Administration (GHA) and MEID -Global
Hexadecimal Administration (GHA) sessions for
co-ordination with Global Numbering
Administrators.
5
Challenges
 ESN resources are exhausted, therefore Global
implementation of MEID and EUIMID for
CDMA2000 is imperative.
 Inconsistent implementation of security in the
networks
• Security is perceived as preventing fraud adequately,
may lead to complacency in some systems
• Cost and complexity are usually cited as reasons for not
using authentication
6
Next Steps/Actions
 TIA plans to continue to monitor the security
environment faced by operators and users
 Any issues identified that are not addressed by
3GPP or 3GPP2 will be studied by TR-45
 TR-8, TR-34, and other TIA Engineering
Committees will continue to work on Security
requirements in their respective standards scope
Next Steps/Actions
 TR-45 EUMAG continues to support ESN/UIM
migration to MEID/EUIMID while maintaining
updates to Numbering Administration guidelines.
 TR-45 EUMAG active participation during 3GPP2
M2M numbering AdHoc studies.

Lawful Intercept
9
Current Activities – Lawful Intercept
• TR-45.8 developing a report based on a study conducted
by the TR-45.8 Lawful Intercept Group (LIG) to determine if
new LAES work is needed to support cdma2000 with
Femtocells.
• TR-45.8 2009 report for TR-45 on Potential Technical
Impacts of the Department of Justice (DOJ) petition to the
FCC regarding asserted deficiencies in the LAES
Capabilities for cdma2000® Packet Data Services (as
specified in ANSI/J-STD-025-B);
 No projects have been undertaken to address the impacts identified in
the report
• Awaiting a final ruling from the FCC
• Report shared with ATIS PTSC LAES and WTSC LI Groups
10
Strategic Direction
 For TR-45 - continue collaboration and
coordination with LI development in groups such
as ATIS WTSC and PTSC and 3GPP SA3 LI.
 TR-45 maintains the J-STD-025 LAES series of
joint standards as the lead SDO .
 TR-45 co-ordinates LAES Object IDentifier (OID)
administration under the “TIA” OID tree branch for
ASN.1 modules.
11
Challenges
 Keeping pace with support of LI capabilities with
the ongoing introduction of new features and
services while maintaining LI standards already
implemented
 Consideration of the unique issues presented with
access to the Internet
• e.g., Local Breakout
 Communications protocols involved in technology
areas such as “Smart Grid.”
12
Next Steps/Actions
 LAES for new CDMA features and services
• Potential new work in support of LI for Femtocells
following the completion of the study
