Near consensus: paperless o Paperless transactions: Law has traditionally presumed the presence of paper records in writing. Near consensus that governments need to make amendments to laws in order to bring media-neutrality of statutes, evidence rules for electronic records (note: email evidence was used in Clinton and Microsoft legal battles), recognition of electronic signatures combined with a reliable certification authority.
No consensus proposals o Privacy only self-regulation ?? o Encryption o Jurisdiction (consensus ??) o Role of private sector, government and international organizations o Content o Internet governance and domain names o Liability of intermediaries
No consensus: Privacy Bad practices: o Keep track of user browsing and choices without his/her consent o Sell user data (e.g., e-mail addresses) o Use spending profile for advertisement o Pull user data from cookies stored in the users computer
No consensus: Encryption o Recommended key lengths public key systems: 1024 bits keys symmetric systems: 128 bits keys o Export Restrictions and Usage for encryption with long keys (e.g. more than 512 bits for RSA and 40-56 bits for symmetric)
Encryption: key length problem o US Data Encryption Standard (DES) 56-bit keys is becoming inadequate o Triple-DES is one improvement: encrypting the output of DES twice using three keys o Long term (20 years): 90-bits symmetric keys are adequate o 128-bit keys: impossible to break o Must distinguish authentication and integrity services from confidentiality services
Encryption: key length problem o RSA RC5 56-bit key crack challenge, early 1997 o Bovine RC5 Effort: tens of thousands computers linked over Internet, more than 4,000 teams o 72 quatrillion (72,057,594,037,927,936) possible keys to test o 268 million key blocks distributed to teams o Peak rate of processing: 7 billion keys/second o Oct 22, 1997: RSA announces successful crack o Conclusion: 56-bit key not sufficient o Remember Moores law: computing power doubles every 18 months (no longer valid)

No consensus: Encryption o Should citizens rights to privacy take precedence over law enforcement concerns? o … not possible to prevent criminals from using encryption … little point in preventing legal users from protecting themselves (Bangemann, European Commission)
No consensus: Encryption o Key escrow: copy of any secret key is deposited with Trusted Third Party (TTP) o National law might require that TTP hands over secret key on certain situations o Key recovery: encryption system allows authorized organizations to rebuild key on request (back door access to private key) o Both schemes allow access to encrypted data
No consensus: Encryption o Some European companies are concerned about using US-based Trusted Third Parties (TTPs), since they may contravene their own countrys data protection laws o A number of countries are becoming concerned about maintaining national root TTPs, to prevent dominance of their national economies by foreign brands
Certification Authority Issues o Issuing certificates is easy o Managing effectively and securely is difficult: CAs must maintain a Certification Revocation List (CRL), must not store private keys (risk of identity theft),... o Trust depends on integrity and security of CAs practices and procedures o Users will have many certificates (e.g., one for Intranet, one for Extranet, one at home) o Interoperability: need for standard

Role of Governments, International Organizations and Private sector o Some E-Commerce frameworks ignore the role of governments & international organizations: everything should be private- sector driven o Jeffrey Ritter, the chairman of the American Bar Association's committee on Internet law, seeks a middle ground between industry and public policy. "The private sector will be mistaken if they believe they can formulate the rules for e-commerce without the input and consultation of governments," he said.
International coordination frameworks Considering that time is ripe to: 1. seek a better international understanding on how to achieve a friction free and borderless marketplace while meeting general public interest objectives 2. define the key issues that require strengthened international coordination 3. many organizations are proposing frameworks for global E-commerce coordination
Need for a global framework The global electronic marketplace requires an appropriate framework covering technical, commercial, and legal aspects. This should foster interoperable technical solutions, competitive business practices and consistent rules. It does not need to consist of detailed and harmonised rules on all relevant aspects. What is required is a concerted examination of the problems and the priorities, in order to allow the international community to address them in a substantive and coordinated manner.
Need for global framework o Building trust in electronic commerce by ensuring the security and privacy of transactions and data, and the protection of consumers. o Establishing ground rules so that commercial laws, tax and customs tariffs, trade policy and market access, and intellectual property measures create a level playing field for electronic transactions.
Need for global framework o Enhancing the information infrastructure through common interoperable standards, and access to open networks. o Maximizing the benefits of electronic commerce by developing awareness and skills, encouraging widespread SME adoption, and ensuring participation and use by all countries.
Conclusion While waiting for all these issues to be addressed, it is important for Governments to work with the relevant stakeholders (international organizations, public and private sector and civil society) to promote policies that will enhance the development and use of electronic commerce.
