SEAL aims at providing an open and comprehensive approach to
global secure electronic commerce over the GTPNet, Internet, public
information networks and private IntraNets.
Moving from closed environments to
interoperability through the SEAL Global Secure Chain concept.

Why do Trade Points need a Secure Electronic
Authenticated Link SEAL to perform Secure Electronic Trading operations.
As we know, the world of Electronic Trading and
Information Technology is constantly under development. We are
constantly seeing new computerization processes, and new concepts of
communication are continually emerging. Placing all this in a business
environment, such tools are being seen as inevitable in today's world
of Electronic Trading. However, it must be noted that Electronic
Trading can only seriously help one's business and provide a proper
competitive edge if it is looked into as part of a proper business
re-engineering process. There is a global believe that network security
is simply a technological issue related to software and servers, but in
reality, it involves people and processes as well.
Businesses need to move securely now so as to ensure
that the potential provided by Electronic Trading is maintained with
regard to productivity, customer satisfaction and globalisation, and
all with a sense towards international trade. A way to solve one
business problem in todays fast running electronic world is by
allowing companies around the world in setting their network security
policy in order to assure that a security solution will meet their company's
objectives effectively. The security policy must correlate and
integrate with their current or planned information systems
architectures. This process will, in turn, drive enterprise-wide
policies, procedures, standards, and guidelines for security in the IT
environment, both developmentally and operationally.
In a global scale the GTPNet is consider the best and only global
architecture which could secure electronic commerce under the
certification process of the United Nations umbrella. Trade Points are
already certify centers on which UNCTAD provides the first level
certification before they are considered operational. This
certification is provided following pre-established and mutula agreed
trade efficiency guideliness. The next step is to inteconnect this
environment via a Secure Electronic Authenticated Link which provides
the authorization and authentication of each individual node. The SEAL
network security solution focus on five main areas and form a solid
framework to implement a Secure Electronic Commerce network security
policy.
-
Access Verification and Control. Information is verified,
controlled and access is granted by a predetermined security policy.
-
Privacy by Secure Links. Secure communication means that
other people on the network cannot see the contents of the message
being sent.
-
Authorization/Authentication. Granting rights for users to
perform actions that would otherwise be disallowed and making sure
that communication is conducted with the intended user.
-
Integrity. The property of data or information resources
have not been improperly altered or destroyed.
-
Management. Consistent framework for managing the security
products and procedures.
How to Secure the GTPNet
Most Trade Points and related Trade Facilitation bodies (Customs,
Transport, Banks, Insurance, etc) together with Trade Promotion
Organizations local and and state governments have complicated data
communications networks that have evolved over several generations of
computing systems. The networks routinely run many different protocols
through Wide Area Networks (WANs) and Local Area Networks (LANs). The
WANs are usually based on a variety of different services over costly
leased lines to maintain a high degree of availability, security and
data integrity. In addition, most companies have Internet connectivity
and routinely run World Wide Web (WWW) sites that are loosely coupled,
if at all, to their corporate networks. The reasons for the latter are
many and frequently include security and data integrity issues. This
adds to the complexity of managing the Web site and complicates remote
site management for most companies.
The first objective of the SEAL architecture is to provide solutions
for creating secure, virtual private networks over public lines such as
the Internet and via Secure Intranet Links and to evaluate the problems
Trade Points face when trying to build Virtual Private Networks (VPNs)
over public media and assist them on how these can be overcome.

Basic Principles
-
The secure level of the transaction chain depends on the weakest
component
-
Total security is only possible via dedicated secure links
-
To provide domestic and international data communication, processing
services and interface software to Trade Points and related
organizations around the world.
-
The security chain must gurantee global transaction security, from the
smart card insertion in the SEAL terminal to its processing at the SEAL
server level.
-
The system adaptability must preserve the integrity of the security
chain.
-
The security chain gurantees security and interoperability
Main Principles
-
To guarantee each transaction authenticity
-
To guarantee each transaction recovery
-
The security level of a system is that of its weakest link

System Description
SEAL aims at providing an open and comprehensive approach to secure
electronic commerce over the Internet, public information networks and
private IntraNets.
It combines development of software applications for secure electronic
commerce, integration into smart card and kiosk technology and
development of global infrastructures for secure links using private
Intranets.
The current phase of SEAL addresses a coherent security model and a
generic, open security architecture for the electronic marketplace.
This architecture is independent of specific hardware, software, or
network architectures. The most fundamental electronic commerce
services, such as secure offering, order, payment and information
delivery, are also integrated in this first phase.
Background
Networked information systems are experiencing a tremendous growth in
terms of users and traffic as well as publicity. The dominating
application, the Internet-based World Wide Web (WWW), is still
dominated by free-of-charge information systems, but this is expected
to change dramatically in the near future.
WWW will be used for all sorts of electronic commerce and trade. The
same development can be expected for the IBC networks and
"Information Highways." This is particularly visible with the
introduction of the Electronic Trading Opportunity ETO system developed
by the UNTPDC and opeartional on the Internet since 1993. ETO is the
first full EDIFACT trading mechanism operating on Internet and IntraNet
environments.
There are numerous projects and services that aim at electronic
commerce via Internet. Many are US-based. Most of them aim at closed
solutions and concentrate on electronic payments only.
None of them aims at the complete electronic marketplace. None of them
provides a coherent model or architecture. Moreover, not even the
non-technical and security requirements on such an electronic
marketplace are understood completely.
Main Objectives
-
a detailed description of commercial, legal, social, and technical
requirements and options for an electronic marketplace;
-
a coherent model and a generic, open architecture of an electronic
marketplace, independent of specific hardware, software, and network
architectures;
-
specifications, designs, prototype implementations and evaluations for
services enabling electronic commerce;
-
information to the technical, scientific and general public,
standardisation, and other ACTS projects.
Technical Approach
SEAL is developed by an interdisciplinary consortium, combining experts
from hardware and software companies, telecommunications groups,
financeial institutions, IT providers, universities and EDI.
The non-technical requirements part of SEAL is based on the existing
expertise within the consortium, as well as on expert surveys performed
in different countries with Trade Points.
The development and trial part is organised in three phases, each phase
corresponding to an enhanced set of services and trials.
The current phase concentrates on two topics:
-
The development of a framework and architecture for secure electronic
commerce.
-
Within this framework and architecture, the provision of the most
fundamental electronic commerce services, namely, offering, ordering,
payment, and delivery for information services.
The following phases will concentrate on extending the architecture
and developing more advanced services, e.g.:
-
Notary Services. For instance, "fair exchanges" will
facilitate digital analog of registered mail, contract signing,
purchases, etc., where no party can be dishonest with the others by not
fulfilling their part of the commitment.
-
Attribute certificates or credentials with specific privacy properties.
-
Multi-media specific security services like protection of intellectual
property rights.
SEAL uses and integrates existing architectures, tools, and services
where appropriate. Initially, security toolkits developed by
Cryptomathic and GMD will support the necessary authentication and
certification
functions. Payment toolkits will support cash-like (ecash) and
credit-card (iKP/SET) payments.
Development is driven by market requirements and the state of the art
in security and on-line information services. Requirements for
multi-party security and the protection of the users' privacy receive
prime attention.
Key Issues, Expected Results
SEAL develops and will publish a generic architecture for secure
electronic commerce over the Internet.
This will include a design and a Java-based prototype implementation of
a security toolkit for electronic commerce.
The toolkit offers all necessary security services, based on the
concept of "service managers" that provide a generic service
interface to "service modules" that actually provide the
required service. New "modules",
corresponding to specific service implementations and products, can
easily be integrated.
Although the initial version of the toolkit will be based on existing
modules only (like the payment modules "ecash" and
"iKP/SET"), new protocols and modules will be developed and
integrated where necessary for the subsequent phases.
This concept allows for specific configurations (e.g., some modules
might not be required by some users, or might not be allowed to be used
in some countries) and ensures interoperability of different modules to
the extend possible.
