Itu t s role in facilitating e services

1. Staying competitive: ITU-T’s dramatic changes to respond to market needs

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Structure of itu int l telecommunication union

Structure of ITU = Int’l Telecommunication Union

  • UN Organization

  • 3 Sectors:

    • ITU-D: aid to developing countries

    • ITU-R: radio spectrum & satellite slot allocations

    • ITU-T: standardization

      • Product: Recommendations (= Standards)

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


How does itu t develop recommendations

How does ITU-T Develop Recommendations?

  • Consensus of

    • Sector Members (= private industry) &

    • Member States (= Governments)

  • Work typically driven by private industry

  • Open (for members), transparent, bottoms-up process

  • Sensitive to national sovereignty: will only cover matters not considered to be national

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Competition in ict tandardization

Competition in ICT $tandardization

  • Standardization has become a MARKET because of

    • Liberalization of telecom industry

    • Internet

  • Market laws rule: demand and supply

    • About 500 fora and standards organizations …

    • … compete & cooperate

    • A shakeout will reduce their number, but …

    • … new technologies will bring new fora

  • Market pressure forced, and continues to force, ITU-T to adapt in order to stay competitive

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Itu t s speedy gonzales approval procedure

ITU-T’s “Speedy Gonzales”Approval Procedure

  • Old days:

    • Before 1988 4 years

    • 1997-20009 months

  • Today:

    • NEW: Alternative Approval Process via email

      (except regulatory Recommendations)

    • 95% of all Recommendations use AAP

    • Average approval time: 9 weeks

      (arguably one of the fastest approval procedures in the market)

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Itu t s speedy publication procedure

ITU-T’s Speedy Publication Procedure

  • Old days:

    • 2-4 years

  • Today:

    • Recommendations available on web a couple of days after approval!

      (so-called pre-published version)

    • Published Recs: 3-9 months

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Itu t s easy online access for recommendations

ITU-T’s Easy Online Accessfor Recommendations

  • Old days:

    • Paper

  • Today:

    • Website, CD-ROM, Paper

    • Free online access since Jan. 2001

      • one free access/member;

      • 3 free downloads for public

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Itu t fosters cooperation

ITU-T Fosters Cooperation

  • MoUs, e.g.

    • IEC, ISO, ITU and UN/ECE on e-business, March 2000

    • See: www.itu.int/ITU-T/e-business/mou/index.html

  • 2nd Informal Forum Summit, 24&25 July 03, San Francisco

  • “IETF & ITU-T Collaboration Guidelines”: updated Aug 2002

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Strengths of itu t

Strengths of ITU-T

  • Unique partnership of industry & government

  • Truly global

  • Consensus decisions guarantee wide acceptance

  • Fast procedures

  • Brand name

  • IPR Policy

  • World-class meeting facilities

  • Excellent Secretariat staff

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Itu t s role in facilitating e services

2. ITU-T’s contribution to e-services:

  • Security: X.509 certificates

  • Transfer Syntax: ASN.1

  • Exploration of “e-services” through workshops

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Security a fundamental shift is happening

Security - A Fundamental Shift is Happening

  • Computers & networks are becoming a utility (like water, electricity, gas, telephone)

  • Business and personal life are more and more dependent on computers

  • Prerequisite: adequate security.

  • [9/11 terrorist attack confirmed the already existing trend of emphasizing security]

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Secret key encryption

Secret Key Encryption

Plain textPlain text



encrypt message with decrypt message with

secret key same secret key

 cipher text

  • Both parties share a single, secret key

  • Problem: exchanging keys in complete secrecy is difficult

  • Best-known example: DES (Data Encryption Standard)

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Public key encryption

Public Key Encryption

Plain textPlain text



encrypt message with decrypt message with

public (!) key of receiver (!) private key of receiver

 cipher text

  • Each participant has

    • A private key that is shared with no one else, plus

    • A public key known to everyone

  • Problem: slower than Secret Key Encryption

  • Best-known example: RSA

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Public key infrastructure

Public Key Infrastructure

  • How do we know that Alice’s public key really belongs to Alice?

  • Answer: PKI

    • Through PKI, we know that a public key belongs to a given user

    • Public key is given to the world encapsulated in an X.509 certificate

    • Trusted “Certificate Authorities (= CA)” sign certificates.

    • Main task of PKI is to issue and manage public key certificates

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03


Transfer syntax asn 1

Transfer Syntax (ASN.1)

  • How could e-commerce messages be encoded at the physical (bit) level?

    • ASN.1:

      • provides very efficient encoding methods

      • attracts increasing interest

UNCTAD-UNECE: ICT & E-Commerce Strategies for Development, 20-21 Oct 03
