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

itu t s speedy gonzales approval procedure
ITU-T’s “Speedy Gonzales”Approval Procedure
  • Old days:
    • Before 1988 4 years
    • 1997-2000 9 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

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 text Plain 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 text Plain 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
