Contents

• Overview of ITU-T work on GII and IP networking

• Survey of ITU-T security and encryption standards

• Pointers to new standards requirements


G8 Information Society Projects

• Global Inventory

• Global Interoperability of Broadband Networks

• Trans-cultural Education and Training

• Electronic libraries

• Multimedia Access to World Cultural Heritage


• Environment and Natural Resources

Management • Global Emergency Management • Global Healthcare Applications • Government On-Line

• Global Marketplace for SMEs

• Maritime Information Society


GII Objectives

The GII must be designed to:• enable information providers and users (e.g.

individuals, information users, information providers, and information service providers) to communicate securely with each other any time and anywhere at acceptable cost and with acceptable quality


• provide a set of communication services

• support a multitude of open applications

• embrace all forms of information and

information generation (audio, text, data,

image, video, etc.), and of its use and

transportation

• operate in a transparent, user-friendly and straightforward way


• provide seamless, interconnected and

interoperable communication networks,

information processing equipment, data-

bases and terminals (including TV-sets)

• enable competition between the players in

the information and telecommunications

(including broadcasting) sectors


GII Projects

• Frameworks

• Network issues

• Middleware

• Applications


IP Aspects

• Explosive growth of IP based networks

• Data traffic growing ten times faster

than voice traffic

• In near future will account for over 80%

of all traffic on telecomms networks

• Business directions are changing


• Shorter development cycles

• Shorter life cycles for services and

products

• Standards bodies must be able to

respond


• Interoperability of IP and telecomms networks and of their services is of major concern

• IP based services are required with the speed, capacity, ease of use, reliability and integrity that has been associated with the world wide public telephone network


The ITU-T IP Project In its capacity as ‘Lead Study Group for

IP related studies’ Study Group 13 has

developed an ‘ITU-T IP Project’ which:

– is separate from, but closely related to GII

studies

– is intended to encompass all related ITU-T

work


Project Areas

• Area 1 - Integrated architecture

• Area 2 - Impact to telecommunications

access infrastructures of access to IP

applications

• Area 3 - Interworking between IP based

network and switched-circuit networks,

including wireless based networks


• Area 4 - Multimedia applications over IP

signals• Area 5 - Numbering and addressing• Area 6 - Transport for IP-structured signals• Area 7 - Signalling support, IN and routing

for services on IP-based networks• Area 8 - Performance


• Area 9 - Integrated management of telecom

and IP-based networks

• Area 10 - Security aspects

• Area 11 - Network capabilities including

requirements for resource management

• Area 12 - Operations and Maintenance (OAM)

for IP

IP Project Area 10 – Security Aspects

Scenarios include:• A voice call from an IP terminal connected to an

IP-based network to a GSTN phone • A voice call from a GSTN phone to an IP terminal

connected to an IP-based network • A voice call from a GSTN phone to another GSTN

phone via an IP network• A voice call from an IP terminal connected to an

IP-based network to another IP terminal connected to an IP-based network via the GSTN


Rec X.509

Information technology – Open SystemsInterconnection – The Directory: Authentication

framework

• Issued jointly with the ISO• Version 6 currently being worked on, target 2001• Amendments provide extensions to the Directory to

support enhancements for public key certificate and attribute certificate framework extensions and certificate revocation.


Other current work in Study Group 7

• Rec x.sio Information Technology – Security Techniques – Security Information Objects

• Rec x.ttp1 Information Technology – Security Techniques – Guidelines on the use and management of Trusted Third Party services

• Rec x.ttp2 Information Technology – Security Techniques – Specification of TTP services to support the application of digital signatures


Security work in Study Group 16 related to multimedia

• Rec H.233 Confidentiality system for audio visual services

• Rec H.234 Encryption key management and authentication system for audio visual services

• Rec H.235 Security and encryption for H Series (packet based) multi media terminals


GII Project M3Technical Framework for Electronic

Commerce• the support of standardized transactions, i.e.

presentation of the offer, navigation and selection

• the exchange of commercial documents such as orders, invoices, contracts

• the support of delivery, especially with regard to electronic goods

• a high level of security• means for the support of payments


Pointers to new standards requirements

• Much of the current debate is not about standards but the security environment and administrative / regulatory issues

• Many of the necessary standards are in place or are being enhanced but further extensions could be considered to support and / or enable further harmonisation of authentication technologies


Possible areas for further standards work

• Additional information fields in Rec X.509?

• Addition of generic attributes plus various extensions for different contracts etc?

• Extensibility profiles?

• Others?
