What type of documents comprise the P25 Standard?

• Overview – high level interface requirements

• Messages & Procedures (M&P) – detailed technical description

• Measurements – what and how to measure

• Performance – what to expect in the measurements

• Conformance – did it do the job per the published M&P

• Interoperability – does it work with other manufacturers

• Compliance – tests deemed necessary for assessing manufacturer interoperability. Performed by P25 CAP labs

Depending on the interface and it’s maturity and/or complexity,

each of these documents may not be needed for all interfaces

ISSI Architecture

• The ISSI architecture is based on the concept of a “Home” and a “Serving” RFSS: – The “home” RFSS represents the home based location and radio coverage

area under which a particular talk group and/or individual operates.

– A “serving” RFSS represents a foreign location and radio coverage area to which a talk group (or certain members of a talk group) and/or individual has roamed, and is away from the home-based radio coverage area

• ISSI TIA 102.BACA-B Messages & Procedures (trunked) – ISSI Messages and Procedures defines the basic ISSI protocol for trunked

voice and mobility management operations

– Based on SIP for session/call setup, control, and teardown

– Uses RTP for transmission of P25 IMBE voice packets and PTT floor control

Project 25 Security Services Update

Bill Janky

Director, System Design

Harris Corporation

74 Project 25 Technology Interest Group March 11, 2013

3/15/2013

38

Agenda

• Overview of P25 Security Services

- Confidentiality

- Integrity

- Key Management

• Current status of P25 security standards

- Updates to existing services

- New services



3/15/2013

39

Why do we need security? • Information security is a vital component of LMR systems

– Security threats exist; getting more every day

• What’s a threat? Threats are actions that a hypothetical adversary might take to affect some aspect of an LMR system. Examples:

– Message interception

– Message replay

– Spoofing

– Misdirection

– Jamming / Denial of Service

– Traffic analysis

– Subscriber duplication

– Theft of service


What P25 has for you…

• The TIA-102 standard provides several standardized security services that have been adopted for implementation in P25 systems.

• These security services may be used to provide security of information transferred across FDMA or TDMA P25 radio systems.

Note: Most of the security services are optional and

users must consider that when making procurements


3/15/2013

40

The usual suspects…

• P25 provides

– Confidentiality

• Payload (i.e. voice and data) encryption

• Link layer encryption

– Integrity

• User authentication

• Message authentication

– Key Management

• Manual key loading and over-the-air rekeying

Message interception, traffic analysis

Message replay, spoofing, misdirection, denial of service, theft

of service, subscriber duplication

Facilitates Confidentiality and Integrity


Confidentiality • The confidentiality services are provided to ensure that the

signaling information, the voice traffic and the data traffic are understandable only to the intended recipient(s). – Encryption/decryption is the way to achieve confidentiality

• Confidentiality service for end-to-end encryption is typically done at the subscriber unit, console and data hosts.

• Confidentiality services are built into the P25 protocols.

If you don’t want somebody to hear you, or see

your data, you need to use encryption.

This is top secret Got it.

Thanks for sharing!

This is also secret

3^@(*@9 )#2R)7(#Q#85r%$92

Got it.

Confidentiality, or not…


I’m not 100% sure I trust you…

Integrity, or not

3/15/2013

42

Integrity • Messages

– A more sophisticated adversary may have the capability to not only record and replay messages, but to alter them as well. Message authentication guarantees that the received message was the one originally sent.

– The addition of air interface encryption makes message modification more difficult (e.g. sharing of secret keys), but doesn’t eliminate the possibility.

• Message Authentication Codes (MAC) are required to guarantee message and sender integrity.

• Users

– An adversary may “pose” as a real user or as a real system.

– Link Layer (i.e. User) Authentication, LLA, guarantees that everybody is who they say they are.

• Integrity services are built into the P25 protocols.

If you don’t want somebody to fake your data or

your identity, you need authentication services. March 11, 2013 Project 25 Technology Interest Group 83

Hi, I’m Bill Janky

User authentication

Boris

Grrrr…never mind.

Really? OK, do a calculation for

me.

Key Management • The Confidentiality, Integrity and Authentication

services rely on cryptographic keys.

• Cryptographic key management encompasses every stage in the life cycle of a cryptographic key, including:

• generation, distribution, entry, use, storage, destruction and archiving

• P25 provides two ways to help manage keys – manual and OTAR.

Managing keys requires you to have some internal

procedures to combine with P25 standard procedures.

What’s new, what’s coming (cont)

• Security Services Overview Addendum (TIA-102.AAAB-A-1) – Overview of the encryption and key management architectures for voice, data,

subscriber authentication, and air interface encryption. – Revision R5 completes sections 1 through section 7.1.4.2. Next section currently

being drafted.

• KMF to KFD interface – New – Requirements have been reviewed and agreed too. – First draft in comment review, 82 comments submitted, 61 Agreed Resolution, 8

Proposed Resolution, 12 Open, and 1 Closed. – Second draft due for final review after remaining comments resolved.

• Link Layer Encryption standard – New – High-level requirements reviewed and agreed to. – LLE Architecture document is in comment review and architecture concepts are

being merged into an agreed final architecture. – The Standards definition documents will be drafted after the architecture is

finalized.


Keep raising the bar and plugging new holes…

Summary

• If you don’t want unauthorized people to hear you, or see your data, you need to use encryption

– Be aware that sometimes encryption overlaps with user perceptions on audio quality

• If you don’t want bad guys to fake your data or your identity, you need to use authentication services.

• Managing encryption and authentication keys requires you to have some internal procedures to combine with P25 standard procedures.

• The users and manufacturers participating in TIA-102 (P25) standardization are continuing to work to improve security services and add new features.

• System security factors affect mutual aid and interoperability. A sub-set of specific features can be defined as minimum required for mutual aid.

• Finally: Remember that most of the security, encryption, and voice protection features in P25 are optional, not mandatory, and users must consider that when making procurements

– Encryption capabilities are not used by all, but are part of the features in the P25 Guide

CORE DEFINITION DOCUMENTS

TESTING DOCUMENTS

USED TO ENABLE DEVELOPMENT

USED TO VERIFY IMPLEMENTATION

TIA-102

STANDARDS

DOCUMENTS

Core Definition documents are those TIA-102 standards documents that enable manufacturers to independently develop and implement interoperable equipment. Test documents are those TIA-102 standards documents that enable manufacturers to verify that their product implementation adheres to the respective core definition documents The TIA-102 suite of standards are in various stages of completion for each of the P25 Interfaces and Services

Getting to Multi-Manufacturer Interoperability


Types of Tests TIA publishes ?

Interoperability Testing – Interoperability testing includes functional testing between manufacturer A’s

equipment and manufacturer B’s equipment per the Project 25 standard.

Performance Testing – Performance testing includes measurements that verify product specifications

as specified in the P25 standard.

Conformance Testing – Conformance testing includes verification of the messages as specified in the

P25 standard.

Recommended Compliance Assessment Tests (RCAT) – Subset of tests collected from above test documents related to a specific

interface or service. This is vetted out in the TIA forum to provide a reasonable level of testing to insure proper operation among multiple manufacturers

Project 25 Technology Interest Group 98 Project 25 Technology Interest Group 98

3/15/2013

Where does this testing occur?

Best practice has industry running Conformance and Performance tests during development in manufacturer specific labs.

Once a product is released multi-manufacturer interoperability testing can occur.

– This has been demonstrated in multi-manufacturer events both as part of the CAP program as well as independent of the CAP program.

– For P25 CAP testing must be conducted in recognized labs per grant guidance

– A rigorous on-site assessment of each laboratory is performed for technical competence and quality system management.

– This evaluation process ensures that tests are conducted correctly and the results are reliable.


TIA tests are currently published for P25 Common Air Interface

• P25 FDMA Common Air interface

– Conventional Performance

– Conventional Conformance

– Conventional Interoperability

– Trunking Performance

– Trunking Conformance “basic” services

Compliance Assessment Program

• P25 CAP testing ensures that there is a choice

– Multiple vendors subscriber equipment is tested on Multiple vendor Networking equipment

• Provides a mechanism for P25 equipment suppliers to formally demonstrate their products' compliance

– Against a key subset of the P25 Standards

– Performed in CAP recognized labs

• Published results

– After testing SDOCs and STRs are

published by the DHS on the

Responder Knowledge Base

– http://www.rkb.us


CAP Test Results Availability

• Project 25 Testing Results

– Posted by DHS on their RESPONDER KNOWLEDGE BASE: http://www.rkb.us


– Supplier’s Declaration of Compliance (SDoC)

3/15/2013

52

CAP Certified?

• Each piece of P25 equipment must be tested with at least 3 manufactures P25 equipment.

– Each Piece of Subscriber equipment will be listed in at least 3 Network equipment's SDOC and STRS.

• Manufactures with published SDOCS and STRs – Tait

– Kenwood

– Daniels

– EF Johnson

– Harris


– Motorola

– Icom

– Cassidian

– PowerTrunk

– Raytheon

– Simoco

– BK Relm

– Thales

– Datron

Requirements for your unique system

Networks and Subscriber equipment do not need to be purchased together, or even from the same manufacture.

Different user groups have different needs and requirements.

Understand what you need and what is available early in the purchasing process.

RFI – Request for Information

A great way to understand what each different manufacture can offer.

Determine what aspects are important to you and your users.

RPQ – Request for PreQualification

Determine what aspects are important to you and your users, and ensure the equipment meets those needs.


3/15/2013

53

Testing Requirements for your unique system

1. Decide what interoperable P25 interfaces are important for your system (e.g. FDMA CAI, TDMA CAI, ISSI, CSSI, FSI)

2. Determine what features / services are important to you (e.g. Conventional operation, Encryption, OTAR, etc…

3. Determine which features you would like to have interoperability between different manufacturers equipment.

4. Ask for testing results. – A subset of P25 interfaces and features tested in CAP

– For those not covered in CAP look to TIA test documents

– For those not detailed in TIA test docs use Functional Acceptance Tests


Take away

• Understand what functionality is needed for the system and the needs of the users.

• Understand what different manufactures have and be open with your

needs.

• Test results are good to have when selecting a manufacturer

• Use CAP test results when available

– not all P25 functionality covered by CAP

• When CAP results are not available

– request results of published TIA tests to ensure consistent test approaches

• When published TIA tests are not available

– work with the manufacturer to define tests that provide results of interest
