Abstract IEEE 802 ECSG on White Space slide deck to capture 802 and TVWS USE CASE Security Issues

Purpose To provide input to the ECSG and others on possible use cases that will help clarify how the TVWS spectrum might be secured and how these uses might possibly be addressed by IEEE 802 work.

• Each platform abstraction layer supports its own communications security– Note: Media security is generally platform-to-network, not platform-to-platform

• Implementation of each platform abstraction should be secured– Certification of regulatory/standards compliance– Real-time attestation of implementation (“tamper-proof”)– Ability to secure sensitive data– This is not shown, but implied

Secure Datastore Commonalities

• Datastores/Schema all have similarities (FCC, SMA, LHIP, & TNC)– Location information and measurement

• Geolocation, sensor measurements

– Host information:• Identity, name, address, etc.

– Network IDs:• MAC, IP address, etc.

– Local policy databases• Spectrum policy information• Security policies database• Co-existence policies

– Remote database information• DNS, Spectrum Servers, Certificate Authorities, Sensitive SW Sources (e.g. McAfee), etc.

– Trust certificates– Identities of trusted third party connections

• IF should/could be standardized

Interfaces Need to be Defined

• 802.11k SME MIB “Zero Config”-like Access– Object IDs for the MIB Entries

• 802.11 SME MIB Clients• 802.16 MIB Clients• 802.21 MIB Clients• SMA Interface [SLDAP (Secure Lightweight Directory

Access Protocol)]• DNS• TCG’s TNC [IF-MAP (InterFace-Metadata Access Point)]• FCC WS – interface undefined, but required fields

similar

End-to-End Projects Identified

• Joint IEEE-IETF Task Force on end-to-end security protocols and definitions– Passing of SMA/cryptographic identity/security information from PHY

to upper layers (schema?)

• IEEE/802.21 project for security handoff between disparate systems (schema?)

• Joint IEEE-TCG Task Force on device security at lower layers– Attesting to lower layers– Compliance with regulatory/standards policies, e.g. FCC White Spaces

regulations

• Interface definitions for all interfaces in 802

March 2009


Resolutions?

• HIP• SMA Datastore [Secure LDAP (SLDAP)]• DNS Resource Records (Not Secure)• TCG’s TNC Datastore Access (SLDAP?)• All schema (should be common)
